A strong 235/85R16 Load Range F trailer tire should match your trailer’s required capacity and fitment, with the right quantity and construction for your setup. Transeagle ST Radial II leads this selection with a listed 3,968-pound load capacity and the exact 235/85R16 size. The ten options here include individual tires, pairs, and sets of four, so the package matters as much as the tire specification when replacing a full set.
Several listings also note details such as nylon overlays or a scuff guard, while others provide fewer construction specifics. All listed products identify a 16-inch rim size, but shoppers should confirm the vehicle or trailer manufacturer’s requirements before ordering.
Use the comparison to narrow the options, then verify load, speed, fitment, and quantity for your application.
Transeagle ST Radial II is the best overall match in this group because it is an ST235/85R16 tire with a listed 3,968-pound load capacity and 12-ply Load Range F construction. It suits buyers seeking an individual trailer tire in the requested size and range. If you need a set rather than a single tire, Free Country Trailer Tires Set4 adds a full-tread nylon overlay and scuff guard, while Mastertrack UN203 Set4 lists a three-year road warranty.

Best for: Commercial trailer hauling.
Why it ranks #1: This exact-size ST tire is listed as 12 ply, Load Range F, and 3,968 pounds capacity, making its key fit and capacity facts explicit.
A listed 3,968-pound load capacity is the key differentiator for the Transeagle ST Radial II, supporting buyers seeking a 235/85R16 F-rated trailer tire for substantial loads.

Transeagle describes its commercial and trailer tires as offering handling, load durability, and traction, relevant qualities for road use with a loaded trailer. The 235/85R16 size and 16-inch rim specification help with size planning, but the supplied details identify only the tire, so mounting hardware is not included in the listed components.

Together, these features speak to buyers concerned about tread reinforcement and sidewall scuffs during trailer use. The set of four supports a multi-tire replacement workflow; rims are not included, and the product is specified for trailer use only, so it is not presented as a vehicle tire.

Why it ranks #4: This set of four lists ST235/85R16, 12 ply, and 3,960 pounds capacity; its nylon overlays cross the tread area.
A specialized decoupling groove is the Travelstar Ecopath’s clearest differentiator, with the supplied facts saying it helps prevent irregular wear by distributing tread forces. The set of four also uses nylon overlays for strength and puncture resistance, giving trailer owners concrete construction features to weigh alongside its 12-ply 235/85R16 specification.
Travelstar says the decoupling groove distributes forces across the tread to promote more even wear, a feature relevant to owners focused on tire life. Nylon overlays are described as enhancing strength and stability while resisting punctures, adding a second practical consideration for trailer operation. The four-tire set supports multi-position replacement, and the listed 3,960-pound capacity and three-year road warranty provide further comparison points. The listing notes that packages may arrive on different days.

Why it ranks #7: The pair is specified as ST235/85R16, 12PR, and Load Range F, with a full nylon cap ply and scuff guard.
A full-tread nylon cap ply and Scuff Guard ring distinguish this two-tire Free Country package for trailer owners replacing a pair. The 235/85R16 radial tires carry a 12PR Load Range F specification and a listed 3,960-pound capacity, combining protective features with practical load information for replacement planning.

Why it ranks #8: This pair lists ST235/85R16, 12-ply Load Range F construction, 3,960 pounds capacity, and a three-year road warranty.
A two-tire package gives the Mastertrack UN203 a clear role for trailer owners replacing a pair rather than ordering four tires. Each ST235/85R16 tire is listed as 12-ply, Load Range F, and 3,960-pound capacity, and the product specifies a three-year road warranty for buyers weighing ownership coverage.
The set of two supports a paired replacement plan, while the ST235/85R16 designation identifies the trailer tire size to compare against the existing setup. Its 12-ply Load Range F rating and listed 3,960-pound capacity give useful reference points for checking the trailer’s load requirements. Mastertrack lists a three-year road warranty, but the supplied specifications do not detail added tread reinforcement or sidewall protection features, so buyers focused on those features have less information here.

- Weight: 36 lb
Best for: Single tire with Scuff Guard.
Why it ranks #9: This individual ST235/85R16 radial is listed as 12PR Load Range F and includes the Free Country series scuff guard.
A Scuff Guard feature distinguishes this Free Country Prem trailer tire for buyers replacing one tire and seeking added sidewall protection. The listing identifies a 235/85R16 radial tire with a 12PR Load Range F rating and a stated 3,960-pound capacity, offering practical specifications to compare with a trailer’s existing setup.
The title names the Scuff Guard, a feature associated with sidewall protection in this tire line, giving buyers a specific point of interest when considering trailer-tire wear. Its radial construction, 12PR Load Range F rating, and 235/85R16 size help establish the tire’s type and fit category for replacement planning. The listing describes a single tire, rather than a set, so owners changing several positions will need to plan quantities accordingly.

10. WINDA Semi Steel Trailer Tire
- Load Capacity: 3960 lb
- Size: 235/85R16
- Rim Size: 16 in
- Weight: 36 lb
Best for: Semi-steel trailer tire shoppers.
Why it ranks #10: This semi-steel trailer radial is listed as 235/85R16, 12PR, Load Range F, and 3,960 pounds capacity, though fewer construction details are supplied.
The WINDA listing specifies a semi-steel radial construction in 235/85R16 with a 12PR Load Range F rating, giving trailer owners a clearly identified construction and load-range combination to assess. Its listed 3,960-pound capacity and 16-inch rim size add practical reference points when comparing replacement tires against a trailer’s requirements.
A 12PR Load Range F rating and the stated 3,960-pound load capacity help frame whether the WINDA tire suits the intended trailer load. Its semi-steel radial description identifies the construction, while the 235/85R16 size and 16-inch rim specification support size checks before arranging mounting. The supplied information does not list a multi-tire set or added protective features, so this option is best evaluated as a specification-focused tire rather than a package with extra accessories.
- Semi-steel radial construction
- 12PR Load Range F rating
- Listed 3,960-pound load capacity
- 235/85R16 size and 16-inch rim specification
- The supplied listing does not specify a set quantity.
Skip it if you need a clearly stated four-tire package; the supplied WINDA details do not specify a set quantity.
Consider the WINDA for a trailer owner prioritizing a semi-steel radial, 12PR specification in 235/85R16. Its supplied details leave package quantity unspecified, so verify the listing quantity before planning a complete replacement.

View on AmazonAvoiding trailer tire fitment and loading mistakes
The main fitment trap is treating the size and load range alone as proof that a tire is suitable for a particular trailer. These listings identify 235/85R16 tires and 16-inch rims, but that does not confirm clearance, wheel compatibility, or the trailer’s required load and speed ratings. Check the trailer’s placard and manufacturer guidance, then compare the tire’s full sidewall markings and capacity with the required specification.
Also distinguish a single tire’s stated capacity from the load supported by a complete axle or trailer; the listings do not establish allowable axle loading. Product titles include different speed-index markings, such as 128/124L for Transeagle ST Radial II and 128N for some Free Country listings, so do not assume every tire has an identical rating.
Confirm the exact listing and tire markings before fitting, especially if replacing only part of a set.
Why package quantity and construction details matter
Package quantity and construction details can change what a listing is useful for, even when the size matches. This selection includes individual tires, pairs, and sets of four; buying a set does not by itself establish that its tires should be fitted together with existing tires. Check the seller’s package contents and your trailer maker’s replacement guidance.
The Free Country listings describe a nylon overlay across the tread and a scuff guard, while Travelstar Ecopath ST also specifies nylon overlays and a decoupling groove. These are listed design features, not proof of comparative performance or a guarantee against failure.
Other products, including Transeagle ST Radial II and Suntek HD Trail 2, provide load and size details but fewer construction claims in the supplied information. If a feature matters to your use, verify that it appears on the exact product variation you order.
How to Choose a 235/85R16 Load Range F Tire
Listed load capacity
Look for a stated capacity that meets your trailer maker’s requirements, rather than choosing by size alone. The products with explicit figures list either 3,960 pounds or 3,968 pounds per tire: Transeagle ST Radial II, Suntek HD Trail 2, and Roundrule ST Set4 list 3,968 pounds, while Free Country Trailer Tires Set4, Mastertrack UN203, and Travelstar Ecopath ST list 3,960 pounds. The difference between these listed values is small, but a capacity figure is not a substitute for checking the required tire rating and axle limits.
Buyers whose specifications allow either listed figure can compare other features and package quantity. If your trailer documentation calls for a particular minimum, favor only products whose verified markings and capacity meet it.
Single tire, pair, or set of four
Choose a package quantity that fits your replacement plan and confirm exactly what the listing includes. Transeagle ST Radial II, Suntek HD Trail 2, Grand Ride Prem Trailer Tire, and WINDA Semi Steel Trailer Tire are listed as individual tires; Free Country Trailer Tires Set2 and Mastertrack UN203 Set2 are pairs. Free Country Trailer Tires Set4, Mastertrack UN203 Set4, Travelstar Ecopath ST, and Roundrule ST Set4 are sets of four.
A single tire may suit a one-tire replacement when permitted by the trailer manufacturer, while a pair or four-tire set may better match a broader replacement need. Do not infer compatibility with tires already on the trailer from package size.
Follow the trailer maker’s guidance on replacing tires together and check package contents before ordering.
Construction and protection features
Compare explicitly listed construction details when you want a particular design feature, but treat them as specifications rather than performance guarantees. Free Country Trailer Tires Set4 and Set2 describe a nylon overlay across the full tread and a scuff guard. Travelstar Ecopath ST lists nylon overlays and a decoupling groove.
Transeagle ST Radial II is identified as a 12-ply tire, while Suntek HD Trail 2 is described as a semi-steel radial and 12 ply. These descriptions vary in specificity, so the absence of a feature in a listing does not prove that a tire lacks it; it means the supplied data does not confirm it.
Buyers prioritizing listed tread reinforcement or sidewall protection may prefer Free Country or Travelstar, while shoppers focused on clearly stated size and capacity can compare Transeagle or Suntek.
Which 235/85R16 Load Range F tire should I choose?
Choose Transeagle ST Radial II if you want an individual tire with a clearly listed 3,968-pound capacity and 12-ply Load Range F construction. For a four-tire package with stated tread protection details, choose Free Country Trailer Tires Set4; its listing specifies a full-tread nylon overlay and scuff guard. Mastertrack UN203 Set4 is another set-of-four option and lists a three-year road warranty.
If you need a pair rather than four tires, compare Free Country Trailer Tires Set2 with Mastertrack UN203 Set2; the former lists nylon reinforcement and a scuff guard, while the latter lists a three-year road warranty. Roundrule ST Set4 also lists 3,968 pounds capacity.
Before selecting any option, confirm your trailer’s required load and speed ratings, wheel fitment, and replacement quantity.
Frequently Asked Questions
How do I confirm that a 235/85R16 ST tire is approved for my trailer?
Confirm approval by checking your trailer manufacturer’s documentation and the tire’s sidewall markings. Verify the ST designation, 235/85R16 size, load range or load index, speed rating, and wheel compatibility against the trailer’s requirements. If the documentation does not clearly establish a match, ask the trailer or tire manufacturer before buying.
How many tires should I replace at once, and can I mix tire models?
Replace the quantity required for your trailer’s condition and setup, and avoid mixing models unless the trailer manufacturer or a qualified tire professional confirms it is suitable. Keep tire size, load and speed ratings, and fitment appropriate across the axle. These listings include individual tires, pairs, and four-tire sets.
What load and speed ratings should I verify before towing?
Verify that each tire’s load rating meets or exceeds the requirement for its position on your trailer, and that its speed rating is suitable for your intended towing. Compare the trailer documentation with the tire sidewall and product listing; do not rely on size alone. Ask a qualified tire professional if the requirements are unclear.
How should I choose between a single tire, a pair, and a four-tire set?
Choose the package that matches the number of tires you need to replace while maintaining an appropriate setup for your trailer. The group includes individual tires, sets of two, and sets of four. Before ordering, confirm the required replacement quantity and whether the selected tires are compatible with the remaining tires.
What protection or warranty details are listed for the set options?
The Free Country four-tire set lists a full-tread nylon overlay and scuff guard; its two-tire set lists nylon reinforcement and a scuff guard. The Mastertrack UN203 sets list a three-year road warranty. Compare those stated details with your priorities, and check the listing for the exact package and coverage terms.
Final Words
For an individual tire, Transeagle ST Radial II is the clearest match here: its listing specifies ST235/85R16, 3,968-pound capacity, and 12-ply Load Range F construction. For four tires, compare Free Country’s stated tread protection with Mastertrack UN203’s listed three-year road warranty; for a pair, compare the corresponding Free Country and Mastertrack options. Before ordering, verify load and speed ratings, wheel fitment, and replacement quantity for your trailer.
