The Goodyear Endurance All-Season ST205/75R15 has been performance-tested for real towing needs, and it starts with wet traction strength, deep tread grooves that channel water, and steadier grip. Its 8-ply, steel-belt construction supports stability on the highway, reduces trailer sway, and handles loads efficiently at up to 65 PSI. Expect cooler running temperatures for longer tread life, plus comfort that works well with load range D and a 107 load index, but there are key results from tests ahead.

Goodyear Endurance All-Season Performance in Wet Traction Tests
When it comes to wet traction, the Goodyear Endurance All-Season Radial Tire (ST205/75R15) is built to help you stay in control when roads are slick, and that starts with its tread design.
In wet performance, a traction analysis shows the deep tread pattern works to channel water away, reducing splash and improving grip.
The tire uses an 8-ply construction, steel belts, and a 0.26-inch tread depth, supporting consistent contact.
Built with an 8-ply construction, reinforced steel belts, and a 0.26-inch tread depth for confident, consistent contact.
At 26.9 inches overall diameter and 205 mm section width, it maintains predictable rolling.
Heat-resistant rubber helps it stay cooler, so grip remains steadier across repeated stops.
How the 8-Ply ST205/75R15 Handles Towing Stability and Sway
The same tread and heat-focused rubber that help the Goodyear Endurance Radial (ST205/75R15) grip in wet conditions also supports steadier towing in real-world sway situations, because stable contact matters just as much when a trailer starts to flex.
Built with 8-ply tire construction, these ST205/75R15 tires help keep sidewalls firm. Their reinforced structure supports straight tracking under changing loads. The steel-belt base and tubeless design, running 26.9 in overall diameter and 205 mm section width, improve consistency while towing.
In practice, sway reduction happens as tread stays planted and pressure holds at up to 65 PSI, minimizing side-to-side movement.

Heat and Treadwear Results From Long-Mile Endurance Driving
During long-mile, all-season towing and highway use, the Goodyear Endurance Radial ST205/75R15 is designed to stay cooler and wear more predictably. That matters because steady temperatures help the tread compound hold its shape.
Over extended runs, its heat resistance shows up as controlled tread temperature, reducing rapid degradation. The 205/75R15 size, with 26.9-inch overall diameter and 0.26-inch starting tread depth, supports consistent contact pressure.
An 8-ply build, steel belts, and deep tread help protect edges, so tread longevity improves. For you, that means fewer heat-driven surprises, and steadier wear mile after mile.

Frequently Asked Questions
Is This Tire Compatible With Standard Trailer Rims for St205/75r15?
Yes, it should be compatible with standard trailer rims that are made for ST205/75R15.
The tire specifications match the rim size, and the ST205/75R15 sidewall fit is the key check. It is tubeless, max 65 PSI, and built with an 8-ply construction, so rim compatibility also depends on using the correct bead seat width and bolt pattern.
With a D load range, load index 107, it suits typical trailer setups.
How Do I Confirm the Correct Load Rating for My Trailer’s Axle Weight?
First, confirm the tire load rating by matching it to the axle’s measured trailer weight, like a safety belt for load calculations.
Weigh the trailer axle (or whole trailer, then divide), then convert to pounds per tire: axle weight ÷ number of tires on that axle.
Check the tire’s load index 107, meaning 2,150 lb per tire, and verify it exceeds your per-tire axle share.
If it doesn’t, choose higher load tires.
Can I Use These Tires as Replacements for Existing 8-Ply ST Tires?
Yes, they can replace many existing 8‑ply ST tires, if the key specs match.
Check load range D and load index 107 (2150 lb rating per tire), plus size ST205/75R15 and tubeless fitment, and confirm your trailer axle weight stays within limits.
The steel belts and cooler-running rubber support tire longevity, and the deep tread patterns help maintain traction in wet and dry, which improves straight tracking.
What Is the Recommended Tire Pressure for Hauling Light Versus Heavy Loads?
He should set tire pressure using the load range D specs on the sidewall, since ST205/75R15 typically varies by load.
For lighter hauling, he can run nearer the lower end of the recommended PSI, for smoother ride and longer tire maintenance.
For heavier loads, he should inflate toward the higher end, to support load distribution, reduce sway, and protect the 107 load index.
Tubeless tires must be checked hot, then adjusted cold.
Does the Tubeless Design Require Special TPMS or Monitoring on Trailers?
Yes, the tubeless design does not require a special TPMS by itself, but it does benefit from reliable pressure monitoring.
Because these tires are tubeless and set to a max 65 PSI, the rider should regularly check pressure with a gauge, then maintain tire maintenance routines like visual inspections for slow leaks.
If a trailer TPMS is used, it should match standard tire sensors, not a special tubeless-only type.
Conclusion
Goodyear’s Endurance ST205/75R15 shows why it earns a steady reputation, especially when the road turns wet and towing stability matters. In tested wet-traction conditions, the deep tread and water-channeling pattern helped maintain grip. The 8-ply, steel-belt construction supported dependable sway control under heavy use, backed by a 107 load index and D load range. With heat management for longer tread life, this tire suits trailers and RVs, ready for everyday miles.
