Goodyear Endurance RST

Built for trailer axles that scrub. Spread-axle trailers, tight-radius regional routes, drop yards where the box gets swung around all day — duty where the tread gets dragged sideways instead of just rolled. Goodyear’s own positioning calls the Endurance RST its best regional and spread-axle trailer tire for long miles to removal, and it replaces the G619 RST. We quote it in four sizes: 11R22.5, 11R24.5, 285/75R24.5 and 295/75R22.5, all Load Range H.

The mechanism is four parts working together. Goodyear specs an advanced scrub-resistant compound — its own term — so the tread mix is the first line against lateral shear. Above it sits what Goodyear calls a robust shoulder rib design, which the company says helps resist lateral scrubbing and curb damage; that rib sits exactly where a spread axle and a curb do their damage. Then depth: 18/32" in every one of the four sizes, against the 12/32" Goodyear runs on its line-haul trailer patterns — more rubber to give up before the tire comes off the axle. Underneath, the improved casing design is what Goodyear credits for the higher load range: Load Range H at 120 psi in all four sizes, 146/143 L in 11R22.5 and 295/75R22.5, 149/146 L in 11R24.5, 147/144 L in 285/75R24.5. A full load range above the G619 RST, which topped out at Load Range G.

Trailer axles only. Goodyear prints "for trailer use only" three separate times in its own literature for this tire. Do not spec it on a steer or a drive position. It is also not a fuel-economy tire, and that is a determination rather than an oversight: Goodyear badges its Fuel Max LHT, G316 LHT and Marathon LHT trailer lines as EPA SmartWay verified and puts no badge on the Endurance RST. If you are building to a SmartWay-verified spec or running CARB-regulated lanes, this is the wrong tire and we will say so before you order. There is no 3PMSF severe-snow rating and no published M+S marking, and speed is capped at 75 mph. Flat, straight, long-haul van miles are not its best work either — that duty rewards a shallower, lighter, free-rolling rib. One more thing before you commit a fleet spec: the matching Endurance RST UniCircle retread cap is published in 11R22.5, 11R24.5 and 295/75R22.5, but not in 285/75R24.5, so that size cannot be re-capped in the same pattern.

If what you need is the trailer axle covered and nothing more, the Invovic FM591 is the alternative from our own import brand — 11R22.5, 11R24.5 and 295/75R22.5 in 16-ply Load Range H, the same load range as the RST, molded in Cambodia, and the only trailer tire on this store that goes deeper than the RST: 19/32" in the 11R sizes and 20/32" in 295/75R22.5 against the Goodyear’s 18/32". Here is the rest of the trade, on the record. The Endurance RST carries Goodyear’s premium casing warranty: unlimited retreads for seven years from new-tire manufacture or purchase when the casing is retreaded by a Goodyear Authorized Retreader, otherwise coverage through the first retread for seven years, written against exactly these four sizes. It has a named matching retread — the UniCircle Endurance RST cap — and a published engineering data table you can check line by line, per-size weight included: 115 lbs in 11R22.5, 109 lbs in 295/75R22.5. For the FM591 we publish no casing-warranty term, no matching retread cap and no tire weight. On third-party verification the two stand level: neither is EPA SmartWay verified and neither carries a 3PMSF marking. Size coverage is where they part — the two go head to head in 11R22.5, 11R24.5 and 295/75R22.5, and in 285/75R24.5 there is no FM591 to weigh against the Goodyear. Put both on one quote and compare the two delivered numbers — tires, delivery, tax and the state tire fee in one price. Mount-and-balance is your local truck tire shop’s, billed by them.
