Top 5 Heavy Load Trailer Tires in Canada for 2025 — An Expert Guide to High-Load, Reinforced Sidewalls for Horse Trailers

The Goodyear Endurance ST235/85R16 holds a market-leader position for heavy load trailer tires thanks to a trailer-optimized casing, reinforced steel-belt construction and industry-leading heat management that deliver longer tread life under heavy tow loads. Although typically priced above the alternatives in this list, its higher initial cost is offset by superior durability, warranty coverage and lower lifecycle cost compared with value-oriented options like Westlake and Taskmaster. For buyers prioritizing maximum seasonal mileage and reduced downtime, the Endurance outperforms Maxxis and Carlisle on longevity and high-speed heat resistance.

The Maxxis M8008 ST235/80R16 is a strong value-performance choice that balances robust trailer-specific construction with a more accessible price than premium offerings like the Goodyear Endurance. Its heavy-duty sidewalls and tread compound provide good wear resistance and load handling for frequent towing, making it a cost-effective alternative for fleet operators who need better durability than low-cost brands but don’t require top-tier warranty or the absolute longest tread life. Compared with Carlisle and Taskmaster, Maxxis typically offers improved high-speed stability and a better price-to-performance ratio.

The Carlisle Radial Trail HD ST225/75R15 is engineered specifically for trailer service with an emphasis on towing stability, lower rolling resistance and consistent load carrying, giving it an economical middle ground between premium and budget tires. It tends to be priced competitively relative to Goodyear while delivering better towing-specific behavior and casing strength than entry-level brands like Taskmaster, though it may not match the Goodyear or Maxxis for extreme high-temperature endurance. For owners who prioritize steady towing performance and fuel efficiency over maximum tread life, Carlisle offers a technically focused, cost-conscious option.

The Westlake ST235/85R16 Load Range G is positioned as a cost-focused heavy-load option that delivers high load-carrying capacity at a significantly lower purchase price than the premium and mid-tier choices on this list. Its Load Range G rating makes it attractive for budget-conscious fleets and occasional heavy haulers that need maximum GVWR compatibility, but buyers should expect trade-offs in long-term heat tolerance and warranty support versus Goodyear and Maxxis. As a low-cost alternative, Westlake is best when upfront capital cost and load rating matter more than ultimate mileage or warranty coverage.
