Yokohama 108R

This is a regional-haul steer. Yokohama classifies the 108R as Regional-Haul, All-Position/Steer, and it is built for the truck that runs highway miles in the morning and curb-heavy city routes in the afternoon: pick-up and delivery, bulk and straight-truck work, day cabs and sleepers on regional lanes. Yokohama also approves it for dump truck and spread-axle trailer positions, and its own application chart lists it as a premium regional-haul trailer fitment. We quote it in four sizes, 11R22.5, 11R24.5, 285/75R24.5 and 295/75R22.5, all speed symbol L at 75 mph.

What makes it last on that route is depth and sidewall. Every size carries 22/32" of tread, the deepest on-highway all-position tread Yokohama builds, against 18/32" on its RY617 and 20/32" on its 116R. That is simply more rubber to give back before the tire comes off the axle. A sidewall abrasion guard is there to absorb the curbing and scrubbing of urban work: curbs, dock aprons, tight turns through yards. The casing carries Yokohama’s 6-year unlimited-retread casing warranty, and it is worth reading exactly: after the first retread, applied in a manner consistent with standard industry practice, a qualified casing that goes unserviceable from a warrantable condition earns a casing credit. Yokohama runs no named retread program of its own, so the coverage is on the casing when somebody else retreads it. The underlying standard limited warranty runs to the 2/32" wear indicators and not past 5 years from purchase. One size gets a spec-sheet bonus: in 295/75R22.5 load range H, Yokohama publishes an elevated capacity of 7,160 lb single and 6,610 lb dual at 120 psi, where an ordinary 295/75R22.5 H is rated 6,610/6,005.

It is not a long-haul steer. Yokohama puts the 101ZL Spec-2 and RY617 in that slot, and 22/32" of tread is the opposite of a low-rolling-resistance long-haul profile. If your truck lives on the interstate all day, spec the shallower tire. It is not severe-snow rated. There is no 3PMSF symbol on this model, so do not put it on the steer as your winter traction answer. It is not an on/off-highway tire either; Yokohama routes gravel, quarry and site work to the 504C, 505C and 506U. Two size traps worth knowing before you order. 285/75R24.5 is built only in 14-ply load range G at 110 psi, rated 144/141 L, which is 6,175 lb single, materially lighter than the H sizes, and there is no 16-ply H in that size. And 11R22.5 is 146/143 L at 6,610 lb single, so it does not carry the 7,160 lb rating that the 11R24.5 and 295/75R22.5 do. The warranty also excludes road hazard, regrooving or shaving, improper inflation, and tires operated outside the United States.

The Invovic FM303 does the same steer and all-position work, in 295/75R22.5 in 16-ply Load Range H only — one size against the 108R’s four, and 14/32 of tread against the 108R’s 22/32. The FM303 is our own import brand, molded in Cambodia and shipped to us factory direct; the 108R is a US-made Yokohama. The trade is on paper, both ways. The 108R brings a published 6-year unlimited-retread casing warranty with the conditions above, EPA SmartWay verification, and load, inflation, weight and tread-depth figures you can check line by line against Yokohama’s line book. The FM303 carries no published casing warranty and no SmartWay verification, and our Invovic listings are thinner on dimensional detail — we publish no overall diameter, section width, revs per mile or approved rim widths for that line, and its weights are shipping estimates rather than a manufacturer figure. If you run a retread program, or you are bidding work that requires SmartWay-verified equipment, the 108R is the one to spec. Tell us the size, the position and the count and we will put both on one quote, each as a delivered price — tires, delivery, tax and the state tire fee. Mounting and balancing is your local truck tire shop’s or mobile service’s, billed by them at their rate per position.
