A strong 170/80-15 rear motorcycle tire should match your bike’s approved fitment and load requirements while suiting how you ride; cruiser owners have several construction and tread options here. The Michelin Commander II leads this group for riders who prioritize stated longevity alongside stability and handling features. Other choices include a reinforced Shinko SR777 HD, Kenda tires with deep grooves or siping, classic whitewall styling, and Bridgestone options aimed at Japanese cruisers.
Listings vary in size notation, load index, and stated load capacity, so compare the tire markings with your motorcycle manual rather than relying on the nominal size alone. This roundup covers all 10 listed rear tires and highlights the documented differences that matter when narrowing a compatible choice.
The Michelin Commander II is the best overall choice in this group because it is listed as a 170/80B-15 77H cruiser tire and its description emphasizes longevity, stability, and handling. Its stated load capacity is 1,000 pounds, and Michelin cites Amplified Density Technology for responsiveness. Riders needing a reinforced carcass can instead consider the Shinko SR777 HD, while those seeking a whitewall look have a matching Shinko 777 rear option.
Confirm fitment and pressure guidance in your motorcycle manual before buying.

Detailed Reviews: Best 170 80 R15 Motorcycle Tire

#1 · Best Overall
1. Michelin Commander II
- Size: 170/80B-15 (77H)
- Load Capacity: 1000 lb
- Rim Size: 15 in
Best for: Long-mileage cruiser touring.
Why it ranks #1: The 170/80B-15 77H cruiser tire lists 1,000 pounds capacity and highlights longevity, stability, handling, and Amplified Density Technology.
Michelin’s Commander II combines a longevity focus with Amplified Density Technology, which the supplied description says increases responsiveness. For cruiser riders choosing a 170/80B-15 rear tire, that pairing targets extended tire life without giving up the stability and handling emphasized in the listing.
Michelin positions the Commander II for cruisers and cites proven longevity, including third-party testing showing nearly twice the life of leading competitors. Its Amplified Density Technology uses a high-density tire construction, with the description associating the technology with increased responsiveness. Together, those claims address riders weighing tire life against handling feel. The listed size is 170/80B-15 and load capacity is 1,000 pounds; verify the motorcycle’s approved tire specification and load needs before purchase.
- Cruiser-specific tire
- Amplified Density Technology is cited for increased responsiveness
- Longevity is a stated product focus
- Listed load capacity of 1,000 pounds
- Its longevity comparison is tied to the supplied testing claim, not a guarantee for every riding condition.
Skip it if you want the Commander III’s stated velvet sidewall styling; the Michelin Commander III Cruiser specifically lists that appearance feature.
Cruiser riders prioritizing stated longevity and responsiveness should consider the Commander II in the listed 170/80B-15 size. Riding conditions affect tire life, so treat the longevity claim as comparative information, not a personal-use promise.

#2 · Reinforced Carcass
2. Shinko SR777 HD
- Size: 170/80-15
- Load Capacity: 1074 lb
- Rim Size: 15 in
Best for: Heavy-duty cruiser touring.
Why it ranks #2: This 170/80B15 83H rear tire has a reinforced heavy-duty carcass, 1,074-pound listed capacity, and siped wet- and dry-traction tread.
A reinforced heavy-duty carcass distinguishes this Shinko SR777, giving cruiser riders a more stable foundation than the standard version. Its 170/80B15 size, functional tread siping and grooves, and rubber compound aimed at grip and comfort suit riders looking for traction across wet and dry conditions.
Shinko identifies this as a heavy-duty tire with a reinforced carcass, which it says provides greater stability. Functional siping and grooves target wet and dry traction, while the rubber compound is formulated for grip and comfort. The 170/80B15 size and 15-inch rim specification make its intended dimensions clear for cruiser shoppers. Its listed load capacity is 1,074 pounds; compare that figure with the motorcycle’s requirements and follow the manufacturer’s fitment guidance.
- Heavy-duty reinforced carcass
- Functional siping and grooves for wet and dry traction
- Compound formulated for grip and comfort
- Listed load capacity of 1,074 pounds
- The reinforced heavy-duty construction is a specific priority, not a lightweight-oriented feature.
Skip it if you want a whitewall appearance; the Shinko 777 Rear H.D. White Wall offers that styling in a listed 170/80-15 size.
Cruiser riders seeking a heavy-duty rear tire with stated wet-and-dry tread features should consider this SR777. Its reinforced carcass is central to the choice; confirm the 170/80B15 size and load suitability for your motorcycle.

#3 · Six-Ply Construction
3. Kenda Cruiser K671
- Size: 170/80H-15
- Load Capacity: 487 kg
- Rim Size: 15 in
Best for: Wet-weather street cruising.
Why it ranks #3: The 170/80H-15 tire is DOT approved, H-rated, tubeless, and six-ply rated, with offset sipes and a wide contact patch.
Deep offset tread sipes give the Kenda K671 a clear wet-weather focus, dispersing water to support traction in rain. Its six-ply-rated, tubeless construction and H speed rating add practical details for street, touring, and cruiser riders considering a 170/80H-15 tire.
The deep offset sipes are specified for water dispersion and wet-weather traction, which gives rain-conscious street riders a concrete reason to consider the K671. Its six-ply-rated tubeless construction suits the listed sport, touring, and cruiser applications, while the stiff sidewall is intended to improve performance and handling. Kenda also cites a wide contact patch for traction and increased mileage. The 15-inch rim specification helps identify the wheel dimension, but confirm the motorcycle’s required tire type and size.
- Deep offset sipes for water dispersion
- Six-ply-rated tubeless construction
- Stiff sidewall for performance and handling
- Wide contact patch intended to support traction and mileage
- Its H speed rating is stated up to 130 mph, which may exceed what some riders need.
Skip it if you want an explicitly reinforced heavy-duty cruiser tire; the Shinko SR777 HD specifies a reinforced carcass and wet-and-dry grooves.
The K671 suits street, touring, and cruiser riders who value water-dispersing tread and tubeless construction. Its H rating and 170/80H-15 dimensions matter when matching the tire to the motorcycle’s approved specifications.

#4 · Whitewall Styling
4. Shinko 777 White Wall
- Size: 170/80-15
- Load Capacity: 2755 lb
- Rim Size: 15 in
Best for: Classic whitewall cruiser styling.
Why it ranks #4: This 170/80-15 rear HD tire pairs a white sidewall with siped, grooved tread and a listed 2,755-pound load capacity.
Vivid white sidewalls make this Shinko 777 HD the styling-led choice among these rear tires, giving compatible cruisers a classic whitewall look. It also has functional siping and grooves for wet and dry traction, plus a rubber compound formulated for grip and comfort.
The white sidewalls provide the classic appearance Shinko highlights, while its listed availability across common V-Twin and metric cruiser fitments makes that styling relevant to cruiser owners. Functional siping and grooves are intended to support traction in wet and dry conditions, and the compound is formulated for grip and comfort. This is the 170/80-15 rear size for a 15-inch rim. Check your bike’s specified dimensions and load requirements rather than choosing on appearance alone.
- Vivid white sidewalls for classic styling
- Functional siping and grooves for wet and dry traction
- Compound formulated for grip and comfort
- Listed for common V-Twin and metric cruiser fitments
- White sidewalls make it a styling-specific choice rather than a black-wall alternative.
Skip it if you prefer a black-wall heavy-duty tire; the Shinko SR777 HD Black Wall lists a reinforced carcass in the same 170/80B15 size.
Choose this tire if a whitewall finish is important for a V-Twin or metric cruiser and you also want stated wet-and-dry tread features. The 170/80-15 rear size still needs to match your motorcycle’s requirements.

#5 · Wet-Grip Focus
5. Michelin Commander III
- Size: 170/80B-15 (77H) Cruiser Rear
- Load Capacity: 908 lb
- Rim Size: 15 in
Best for: Premium-styled V-Twin touring.
Why it ranks #5: The 170/80B-15 77H cruiser rear tire features a dense casing, velvet sidewall styling, and a description citing enhanced wet grip.
Michelin’s patented velvet sidewall styling gives the Commander III Cruiser a distinctive appearance for V-Twin owners. This 170/80B-15 rear tire is also listed for V-Twin cruisers and touring bikes, so its appeal combines a cruiser-focused fit with a visible sidewall detail.
The velvet sidewall and distinctive tread pattern address riders who care about tire appearance, while Michelin identifies the Commander III Cruiser for V-Twin cruisers and touring bikes. Its 170/80B-15 rear size and 15-inch rim specification help narrow the fitment search, and the listed load capacity is 908 pounds. The description also associates the Commander III Touring line with enhanced wet grip and longevity; check the exact model and motorcycle requirements before applying those details to this Cruiser listing.
- Patented velvet sidewall styling
- Distinctive tread pattern
- Listed for V-Twin cruisers and touring bikes
- 170/80B-15 rear size
- The velvet sidewall is a styling feature, not a stated traction or longevity specification.
Skip it if you want a specifically described longevity claim for this exact model; the Michelin Commander II listing emphasizes proven longevity and comparative testing.
V-Twin cruiser and touring riders drawn to Michelin’s velvet sidewall styling may find this Commander III appealing. Confirm the 170/80B-15 rear size and motorcycle load requirements, and distinguish Cruiser claims from Touring details.

View on AmazonWhy it ranks #6: This 170/80-15 rear tire uses deep, wide grooves, an all-weather traction compound, and an updated shape for straight-line stability.
Deep, wide grooves give the Kenda Kruz K673F its all-weather cruising emphasis, while its updated tire shape targets straight-line stability and cornering. This 170/80-15 rear tire is aimed at cruiser riders who want those road-use priorities in a bias-ply, tubeless design.
Kenda describes deep, wide grooves in the front and rear tread designs for all-weather cruising, and an all-weather traction rubber compound supports that stated use. The updated tire shape targets improved straight-line stability and cornering, relevant to riders balancing steady cruising with turns. Its listing specifies bias-ply, tubeless construction and a 170/80-15 size. Those details can guide a replacement search, but the motorcycle’s approved tire construction and dimensions remain important fit considerations.
- Deep, wide grooves for all-weather cruising
- All-weather traction rubber compound
- Updated shape targets straight-line stability
- Updated shape targets cornering performance
- The listing does not specify a load capacity for this tire.
Skip it if you need a stated load-capacity figure before selecting a tire; the Shinko SR777 HD lists 1,074 pounds for its 170/80B15 model.
The Kruz K673F is aimed at cruiser riders seeking all-weather tread and stability-oriented shaping in a tubeless, bias-ply tire. Its listing gives no load-capacity figure, so check the motorcycle’s requirements before deciding.

7. Bridgestone Excedra G702
- Size: 170/80-15 (Rear)
- Load Capacity: 265 lb
- Rim Size: 15 in
Best for: Japanese cruiser replacement.
Why it ranks #7: The 170/80-15 rear tire is intended primarily for Japanese cruisers and lists a unidirectional pattern for wet and dry surfaces.
Bridgestone identifies the Exedra G series primarily with Japanese cruisers, giving this G702 a clear replacement focus for owners of those bikes. Its unidirectional tread is specified for wet and dry surfaces, alongside claims of long mileage, stability, crisp handling, and riding comfort.
The unidirectional pattern is intended to provide reliable performance on dry and wet surfaces, making orientation and the supplied tire information relevant during installation. Bridgestone also lists long mileage, stability, crisp handling, and comfort as Exedra G-series aims. The G700 series is described as original equipment on models including Yamaha Royal Star, Kawasaki Vulcan, and Suzuki Intruder. This tire is listed as a 170/80-15 rear tubeless tire; the rim is not included, so plan for a tire-only replacement.
- Unidirectional tread for wet and dry surfaces
- Exedra G series is aimed primarily at Japanese cruisers
- Stability and crisp handling are stated priorities
- Tubeless 170/80-15 rear tire
- The listing is for one tire only; the rim and wheel are not included.
Skip it if you want a whitewall finish; the Shinko 777 Rear H.D. White Wall lists vivid white sidewalls for cruiser styling.
Japanese cruiser owners seeking a 170/80-15 rear replacement may value the Exedra’s stated wet-and-dry performance and comfort aims. It is tire-only, so the existing wheel and correct motorcycle fitment remain your responsibility.

8. Pirelli Night Dragon
- Size: 170/80-15
- Load Capacity: 908 lb
- Rim Size: 15 in
Best for: Fast-accelerating cruiser rides.
Why it ranks #8: This 170/80B15 M/C 77H rear tire is listed for cruisers, with product facts describing grip for acceleration and control.
Pirelli’s Night Dragon is presented for riders seeking strong grip during quick acceleration while staying in control. In this 170/80B15 rear size, it brings that performance emphasis to cruiser use, with a 77H specification and a listed 908-pound load capacity.
The supplied Night Dragon facts focus on control and grip under quick acceleration, making that the key reason to consider it over a tire listing mainly mileage or styling features. Its 170/80B15 size and 15-inch rim specification identify the intended dimensions, while the 77H designation and 908-pound load capacity provide additional selection details. The listed contents include a Night Dragon GT tire and Pirelli keychain. Use the motorcycle manufacturer’s tire-pressure recommendation and confirm the required fitment.
- Grip emphasis for quick acceleration
- Control is part of the stated performance aim
- 170/80B15 size for a 15-inch rim
- Listed load capacity of 908 pounds
- The supplied product facts give little tread or construction detail beyond its grip and control emphasis.
Skip it if you want published wet-and-dry siping details; the Shinko SR777 HD lists functional grooves and siping for both conditions.
This Pirelli suits cruiser riders whose priority is the stated grip and control for quick acceleration. Its listing offers limited tread and construction detail, so verify fitment and use the motorcycle maker’s recommended tire pressure.

9. Dunlop D404
- Size: 170/80-15
- Load Capacity: 908 lb
- Rim Size: 15 in
Best for: Older-bike cruiser replacement.
Why it ranks #9: The 170/80-15 rear tire offers a broad fitment range for older bikes and cruisers, with a compound described as balancing grip and mileage.
The D404’s expanded size range is its clearest advantage for riders maintaining older bikes and cruisers. In this rear 170/80-15 size, it pairs a tread compound aimed at balancing mileage and grip, giving everyday street riders a straightforward replacement option from Dunlop’s street-bike tire range.
Its 170/80-15 size and 15-inch rim specification identify the intended wheel dimensions, while the expanded size range addresses a variety of older bikes and cruisers. Dunlop says the tread compound balances mileage and grip, a useful pairing for riders who want wear and road hold rather than a single stated priority. The listing gives a 908-pound load capacity; use the motorcycle maker’s specifications when determining whether this tire suits the bike and its load.
- Expanded size range for older bikes and cruisers
- Tread compound balances mileage and grip
- 170/80-15 rear size
- Listed load capacity of 908 pounds
- Its stated compound benefit is a balance of mileage and grip, not a specific wet-weather feature.
Skip it if you want explicit siping and wet-weather traction details; the Shinko SR777 HD lists functional siping and grooves for wet and dry conditions.
This is a sensible option for a cruiser or older bike needing a 170/80-15 rear tire, especially when mileage and grip both matter. Check the motorcycle’s specified tire size and load requirements before choosing it.

10. Bridgestone G702F
- Size: 170/80-15
- Load Capacity: 908 lb
- Rim Size: 15 in
Best for: Bridgestone cruiser replacement.
Why it ranks #10: This is a listed 170/80-15 77H rear bias tire, but its provided product details offer little beyond the F compound designation.
The G702F is a Bridgestone rear bias tire in the requested 170/80-15 size, giving cruiser owners a clearly identified replacement option. Its listing specifies an F compound, but supplies few further performance details, so the main appeal is a direct size-and-brand match.
The 170/80-15 size and 15-inch rim specification give shoppers concrete dimensions to compare with the motorcycle’s requirements. Bridgestone identifies this as a rear bias tire and specifies an F compound, but the supplied listing does not explain what that compound means for grip, mileage, or weather. Its listed load capacity is 908 pounds. Because the product information is brief, use the motorcycle maker’s approved tire specifications rather than inferring performance from the compound label.
- 170/80-15 rear size
- Identified as a bias tire
- F compound specified
- Listed load capacity of 908 pounds
- The listing does not explain the F compound’s performance characteristics.
Skip it if you need stated wet-and-dry tread features; the Bridgestone Excedra G702 lists a unidirectional pattern for both surfaces.
This G702F may suit a cruiser owner seeking a Bridgestone 170/80-15 rear bias tire with a specified F compound. Its sparse performance description makes it important to verify fit and rely on the motorcycle’s tire guidance.

Listed on Amazon as: Bridgestone G702F Cruiser Rear Motorcycle Bias Tire – 170/80-15 77H
View on AmazonAvoiding size and fitment traps
A matching 170/80-15 label is not enough by itself to confirm a safe fit; verify the complete tire marking and motorcycle requirements. Listings use variants such as 170/80B-15 77H, 170/80H-15, and 170/80-15, and the Shinko SR777 HD is listed as 83H while several others are 77H. Those markings are not interchangeable evidence of fit or capacity.
Check the owner’s manual or the motorcycle’s tire placard for permitted size, load index, speed rating, construction, and whether a tube is required. The Kenda Cruiser K671 explicitly says tubeless, but that alone does not establish compatibility with every wheel.
Also check that the listing is for the rear: these products are described as rear tires, and the Bridgestone Excedra listing says the wheel is not included. Confirm the exact item and tire markings before mounting.
Load capacity is not a substitute for bike requirements
A higher listed load capacity does not automatically make a tire the right choice for a motorcycle. The supplied figures range from 265 pounds for the Bridgestone Excedra G702 listing to 2,755 pounds for the Shinko 777 White Wall listing, while the Michelin Commander II lists 1,000 pounds and the Shinko SR777 HD lists 1,074 pounds. Such a wide spread makes it especially important to verify that the figure is accurate for the exact tire and not to choose by the number alone.
Match the tire’s load index and construction to the motorcycle manufacturer’s requirements and the load carried, including passenger or luggage use. Do not infer a safe operating load from an online listing’s capacity field without confirming the tire sidewall specification.
The manual’s required tire pressure remains the reference; Pirelli’s supplied guidance also directs riders to the motorcycle handbook and tire specification section.
How to Choose a 170/80-15 Rear Tire
Load and speed markings
Start by checking that the tire’s load and speed markings meet your motorcycle maker’s requirements. This selection includes several 77H tires, the Shinko SR777 HD’s 83H marking, and the Kenda Cruiser K671’s H rating; listed load capacities also vary, from 908 pounds on the Dunlop D404 and Pirelli Night Dragon to 1,074 pounds on the Shinko SR777 HD. These figures describe different listed products, not permission to exceed the bike’s limits.
A rider carrying a passenger or luggage should pay particular attention to the required load index, while a lighter-use rider still needs to meet the manual’s minimums. Confirm the sidewall marking and exact fitment before ordering.
Tread and riding conditions
Choose tread features that align with the conditions you encounter, while treating product descriptions as features rather than independent test results. The Shinko SR777 HD has functional siping and grooves for wet and dry conditions; the Kenda Cruiser K671 specifies deep offset sipes and water dispersion; the Kenda Kruz K673F describes deep, wide grooves and an all-weather compound. Bridgestone’s Excedra G702 lists a unidirectional pattern for wet and dry surfaces.
Riders who regularly encounter rain may prefer these explicitly described groove and siping designs, while those prioritizing other factors can compare the Michelin Commander II’s stated stability and handling focus. Tire condition, correct pressure, and motorcycle compatibility remain essential regardless of tread description.
Construction and appearance
Check construction and sidewall style against your motorcycle and preferences. The Kenda Cruiser K671 is explicitly six-ply rated and tubeless, while the Shinko SR777 HD is identified as a heavy-duty version with a reinforced carcass. The Shinko 777 White Wall adds a visible white sidewall, and the Michelin Commander III describes a velvet sidewall finish.
These distinctions can matter for a rider seeking a particular look or a reinforced tire, but they do not replace checking the wheel’s tube requirements, approved construction, and fitment. Choose a whitewall option when appearance is a priority and the motorcycle accepts its specifications; favor documented construction details when matching equipment requirements.
Confirm all details on the product and tire itself before installation.
Which 170/80-15 rear tire should I choose?
For a well-rounded cruiser choice with documented longevity and handling features, choose the Michelin Commander II; it ranks first and lists a 170/80B-15 77H size with 1,000 pounds capacity. Riders who specifically want a reinforced heavy-duty carcass can consider the Shinko SR777 HD, which lists 83H and 1,074 pounds. For explicit six-ply, tubeless construction and offset sipes, the Kenda Cruiser K671 is a strong match to investigate.
Choose the Shinko 777 White Wall if classic whitewall styling matters, and consider the Michelin Commander III for its stated wet-grip focus and velvet sidewall. The Kenda Kruz K673F emphasizes deep grooves and all-weather compound.
Before deciding, confirm the precise markings, wheel compatibility, and pressure requirements in the motorcycle manual.
Frequently Asked Questions
How do I confirm that a 170/80-15 tire fits my motorcycle and rim?
Check your motorcycle manual and the markings on your current tire and wheel before buying. Confirm the required size, construction, load and speed ratings, and whether the wheel needs a tube. The listed tires include variations such as 170/80B-15 and 170/80H-15, so match the complete specifications, not just the nominal size.
Should I choose a bias-ply tire or a different construction for my cruiser?
Choose the construction specified by your motorcycle manufacturer unless its guidance allows alternatives. Several listed options are identified as bias or bias-ply tires; the Kenda K671 is described as six-ply and tubeless in the editorial verdict. Compare the full tire markings and confirm compatibility in your manual before selecting a different construction.
What tire pressure should I use after installing a new rear tire?
Use the pressure specified in your motorcycle manual or on its tire-information label, rather than relying on a generic figure or the tire’s maximum marking. Check the pressure as directed by the manufacturer and follow its guidance for load and riding conditions. Confirm the correct procedure with a qualified tire professional if uncertain.
Which listed tire suits a rider prioritizing a reinforced carcass?
The Shinko SR777 HD is the reinforced-carcass option identified in the editorial verdict. Its listing gives a 170/80B-15 size, 83H rating, and 1,074-pound capacity. Verify that these markings and its construction match your motorcycle’s requirements before choosing it; the Michelin Commander II is the overall pick for longevity, stability, and handling.
Which options should I compare for whitewall styling or wet grip?
For whitewall styling, consider the Shinko 777 Rear H.D. White Wall. For wet-grip emphasis, the editorial verdict points to the Michelin Commander III and the Kenda Kruz K673F; the latter also emphasizes deep grooves and an all-weather compound.
Check each tire’s complete markings and confirm fitment in your motorcycle manual.
Final Words
For a well-rounded cruiser choice, the Michelin Commander II ranks first, with a listed 170/80B-15 77H size, 1,000-pound capacity, and stated longevity and handling features. Choose the Shinko SR777 HD if a reinforced carcass is your priority, or the Shinko whitewall option for that styling. Consider the Kenda K671 for explicit six-ply, tubeless construction.
Before ordering, confirm tire and wheel compatibility and pressure guidance in your motorcycle manual.
