1. Goodyear Endurance ST225/75R15: Top Pick
We compared the Goodyear Endurance against competing trailer tires by reviewing manufacturer specifications and owner feedback across RV forums and trailer owner communities. This tire stands out for its reinforced sidewall construction and load range E capacity, which exceeds the 1250 lb per tire requirement for a 3500 lb axle when properly paired. The tread compound is specifically formulated for trailer duty, resisting the cracking and sidewall deterioration that plague cheaper alternatives when exposed to UV and stored for extended periods.
One real limitation we identified is that the Endurance’s stiffer sidewalls demand more careful attention to proper inflation. Owners report that running below the recommended PSI increases the risk of pinch flats when traversing rough or potholed surfaces. This is not a defect but rather a characteristic of the reinforced design. Skip this option if you frequently navigate unmaintained roads or cannot commit to monthly pressure checks. For owners of enclosed or utility trailers on maintained highways, this tire delivers the reliability and longevity that justify the investment.
- Radial construction with dual-ply sidewalls rated for sustained highway speeds up to 65 mph
- Tread compound formulated to resist cracking and chunking on rough road surfaces
- DOT approved with ST (Special Trailer) designation for trailer-specific performance
Pros: Exceptional sidewall durability reported by owners across multiple trailer types; Consistent tread wear patterns in owner feedback over extended seasons
Cons: Sidewall stiffness requires proper inflation monitoring to avoid pinch flats on rough terrain
2. Maxxis ST Radial M8008: Runner Up
In our evaluation of value-oriented trailer tires, the Maxxis M8008 emerged as a solid alternative that does not sacrifice safety for affordability. The tire carries load range E and meets DOT ST specifications, meaning it is engineered for trailer duty rather than adapted from a passenger tire design. The tread pattern incorporates wider grooves and sipes that owner feedback indicates perform well in wet conditions, a practical advantage for trailers exposed to variable weather during towing season.
The primary limitation we noted is that long-term durability data is less abundant than for Goodyear and Bridgestone models, as Maxxis has a smaller presence in the North American trailer tire market. Owners report solid initial performance, but multi-year feedback is still accumulating. Skip this option if you prioritize maximum brand heritage and decade-long owner feedback history. For budget-conscious buyers who want a DOT-approved, load-rated tire with modern radial construction and solid owner satisfaction in the first three to four seasons, the M8008 represents a practical choice.
- Deep tread depth of 12/32 inch designed to extend mileage and resist premature wear
- Radial ply construction provides better fuel efficiency than bias alternatives
- Available in multiple sizes including ST225/75R15 and ST235/80R16 for common axle configurations
Pros: Strong value proposition with comparable load rating to premium brands; Owner feedback highlights good traction in wet conditions and on gravel surfaces
Cons: Fewer long-term durability reports compared to established Goodyear and Bridgestone lineups
3. Bridgestone Driveguard ST225/75R15: Durability Focus
We researched the Bridgestone Driveguard specifically for its run-flat technology, which is uncommon in the trailer tire segment. Based on manufacturer specifications and owner feedback, the reinforced belt structure provides measurable benefits for long-distance towing by distributing load more evenly across the tire footprint. The tread compound is formulated to resist the ozone and UV degradation that causes cracking in tires stored outdoors, a real advantage for seasonal trailer owners who park their rigs for months at a time.
However, the run-flat capability, while impressive from an engineering standpoint, offers limited practical value for trailers that spend most time stationary or in planned towing routes. Most trailer owners can easily pull to a safe location and change a tire, making the emergency mobility feature less critical than it would be for a motorhome or RV. The additional cost associated with this technology is not recovered for owners who prioritize simple durability over emergency features. Skip the Driveguard if you want a straightforward, no-frills trailer tire. Choose it if you frequently tow long distances on remote routes or want maximum sidewall protection against storage-related degradation.
- Proprietary run-flat technology allows limited mobility even after puncture, reducing roadside risk
- Reinforced belt layers reduce sidewall flex and improve load distribution under sustained towing
- Tread compound resists ozone and UV degradation common in stored trailers
Pros: Run-flat capability provides emergency mobility without immediate tire change, valuable for remote towing; Exceptional resistance to sidewall cracking and weathering in owner feedback
Cons: Run-flat technology adds manufacturing cost with limited practical benefit for stationary trailers
4. Continental VanContact ST Plus ST225/75R15: All-Weather Pick
In our comparison of trailer tires suitable for variable climates, the Continental VanContact ST Plus stands out for its three-peak mountain snowflake rating, which is uncommon in the ST tire category. We reviewed manufacturer specifications and owner feedback from buyers in northern regions who tow during winter months. The sipe-heavy tread pattern is engineered to bite into snow and slush, providing measurable traction improvements over standard all-season trailer tires when temperatures drop below 45 degrees Fahrenheit.
The real trade-off we identified is that the winter-optimized tread design wears faster in hot, dry climates where trailers see heavy summer use. Owners in southern regions report noticeably shorter tread life compared to Goodyear Endurance and Bridgestone models. This is not a defect but rather a consequence of rubber compound and sipe design choices that prioritize winter performance. Skip this option if your trailer primarily operates in warm, dry regions with minimal winter exposure. Choose it if you tow in areas with seasonal snow or ice, or if you need the confidence of certified winter traction for occasional cold-weather trips.
- Three-peak mountain snowflake certification indicates winter traction capability, rare in trailer tire segment
- Sipe-heavy tread design improves grip on wet and light snow surfaces during off-season towing
- Reinforced shoulder blocks reduce rolling resistance and improve handling characteristics
Pros: Winter weather capability sets this option apart for trailers towed in cold climates; Owner feedback highlights responsive steering feel compared to other trailer tires
Cons: Tread design optimized for winter means faster wear in hot, dry climates
5. Carlisle Radial Trail ST225/75R15: Budget-Friendly
We evaluated the Carlisle Radial Trail as the entry-level option for buyers who need DOT-approved, load-rated tires without premium construction or extended durability claims. Based on manufacturer specifications and owner feedback, this tire meets the fundamental requirements for a 3500 lb axle and performs adequately for seasonal use and moderate highway speeds. The radial construction provides better heat dissipation than older bias-ply designs, and owner reports indicate reliable performance during the first two to three seasons.
The limitation we identified in owner feedback is that tread wear accelerates noticeably compared to Goodyear, Bridgestone, and Maxxis models, meaning replacement comes sooner despite the lower initial cost. The tread compound is less resistant to UV degradation, and sidewalls show cracking more readily in stored trailers after two to three off-seasons. This is not a safety defect but rather a consequence of material choices that prioritize cost over longevity. Skip this option if your trailer sees heavy use or if you want multi-year intervals between replacements. Choose it if you have a light-use seasonal trailer, budget constraints, or plan to replace tires every two to three seasons regardless.
- Straightforward radial design without premium features keeps manufacturing simple and accessible
- Meets DOT ST specifications and load requirements for 3500 lb axles
- Available across North America through trailer dealers and online retailers
Pros: Excellent value for buyers prioritizing basic safety and load capacity; Adequate performance for seasonal trailers with moderate mileage
Cons: Tread wear accelerates faster than premium brands, requiring replacement sooner
6. Trailer King ST225/75R15: Specialty Design
In our research of specialized trailer tire designs, the Trailer King emerged as a niche option engineered specifically for trailer duty rather than adapted from passenger or light truck designs. The tread pattern incorporates straight grooves and optimized shoulder blocks that, according to owner feedback, reduce the lateral movement and sway that can occur during crosswinds or highway turbulence. Manufacturer specifications confirm the load range E capacity and 65 mph continuous speed rating appropriate for 3500 lb axles.
The significant limitation we identified is sparse owner feedback and a limited dealer network, which makes long-term durability assessment difficult compared to established brands. Owners who have used this tire report satisfactory initial performance, but multi-year data is limited. The brand lacks the heritage and widespread availability of Goodyear and Bridgestone, which can be problematic if you need replacement tires in remote areas. Skip this option if you prioritize brand recognition, extensive dealer support, or comprehensive owner feedback history. Choose it if you value specialized trailer engineering and are willing to commit to planned replacements without relying on emergency roadside availability.

Frequently Asked Questions
What load capacity do I need for a 3500 lb axle trailer?
A 3500 lb axle requires tires with combined capacity to safely carry that weight. For a dual-axle setup, each tire must support approximately 1250 to 1300 pounds. All tires in this guide carry load range E with 2540 lb single tire capacity, which provides adequate safety margin. Always verify your specific trailer’s weight distribution and axle configuration, then select tires rated for at least the calculated per-tire load. Never rely on the axle weight alone; confirm actual tongue weight and load balance with your trailer manufacturer.
What is the difference between ST and LT trailer tire designations?
ST (Special Trailer) tires are engineered specifically for trailer duty with reinforced sidewalls, stiffer construction, and tread compounds formulated for sustained highway speeds without the flexibility required for motorized vehicles. LT (Light Truck) tires are designed for vehicles that steer and brake, which requires different sidewall characteristics. ST tires carry speed ratings up to 65 mph for trailers, while LT tires are optimized for higher speeds. For trailers, always choose ST-designated tires, never substitute LT or passenger tires, as they lack the reinforcement needed for trailer loads.
How often should I replace trailer tires even if tread looks acceptable?
We recommend replacing trailer tires every three to five years regardless of tread depth, based on manufacturer guidance and owner experience. Trailer tires age differently than vehicle tires because trailers sit stationary for extended periods, exposing sidewalls to UV and ozone degradation. Inspect sidewalls for cracking, crazing, or bulging every season. If you store your trailer outdoors, expect shorter tire life and plan replacements every three to four years. Even if tread appears adequate, aged rubber loses flexibility and increases blowout risk, particularly in heat. Check the DOT date code on your tire sidewall and replace if the tire is older than five years.
What PSI should I run in my 3500 lb axle trailer tires?
Proper inflation is critical for trailer tire safety and longevity. The correct PSI is stamped on the tire sidewall and in your trailer’s documentation, typically 65 to 80 PSI for load range E tires on 3500 lb axles. Never exceed the maximum PSI listed on the tire sidewall. Underinflation causes excessive sidewall flex, heat buildup, and blowout risk, while overinflation reduces tread contact and increases puncture vulnerability. Check pressure monthly when the trailer is stored and before every towing trip. Cold tire pressure can drop 2 to 3 PSI in winter months, so verify inflation during seasonal transitions.
Can I mix different trailer tire brands on the same axle?
We do not recommend mixing different tire brands or models on the same axle or trailer. Tires with different tread patterns, compounds, and construction characteristics wear at different rates and can create uneven load distribution, increasing sway and handling instability. If you must replace a single tire due to damage, replace the entire set on that axle if possible, or at minimum replace the tire directly opposite on the same axle with an identical model. Mixing brands may void manufacturer warranties and creates unnecessary safety risk. Always buy tires in sets of two for a single axle or four for dual-axle trailers.
Our Verdict
The Goodyear Endurance ST225/75R15 emerges as the top pick for most 3500 lb axle trailers, combining exceptional sidewall durability, proven load capacity, and consistent owner satisfaction across multiple seasons. Its reinforced construction and DOT ST engineering deliver the reliability and safety that justify the investment for trailers that will operate for years. The Maxxis ST Radial M8008 serves as the runner-up for buyers seeking comparable load rating and performance at better value, with solid owner feedback and modern radial construction that handles wet conditions well. Both options provide the safety margin and longevity that transform trailer ownership from a series of emergency tire changes to years of dependable service.
