Invovic FM303

A steer and all-position radial for on-highway trucks, in one size and one build: 295/75R22.5, 16-ply Load Range H. This is the front-axle tire in the Invovic line — the position that carries the steering load, has to track straight, and has to wear evenly doing it — and it is rated all-position, so it is also cleared to run back on a trailer axle.

The tread is five continuous ribs cut by four circumferential grooves. No blocks, no lugs. Fine lateral sipes run across each rib and the rib edges are serrated; the supplier gives even wear and stable tracking as the aims and publishes nothing to substantiate them, so that is where the claim stops. The casing is 16-ply Load Range H, rated 6,610 lb single and 6,005 lb dual at 120 psi, and it is the only build: there is no 14-ply Load Range G FM303. If the steer axle runs Load Range G tires today, change both sides together so the axle stays matched.

One number deserves a hard look before you buy: tread depth, which is 14/32 inch. Every major-brand steer tire we quote is deeper: Michelin X Line Energy Z and Firestone FS592 at 19/32, Firestone FS591 at 18/32, Goodyear Endurance LHS at 18/32, Bridgestone R213 Ecopia at 17/32, Yokohama 108R at 22/32. Tread depth is removal miles, so on a steer axle this tire starts with less of them than anything else on this page, and 14/32 is the depth the rest of this catalog carries on trailer tires. The axle position on this page comes from the client’s supplier sheet, not from a published Invovic document — there is no Invovic data book and no US spec site. If you are speccing a steer axle, ask us for the position rating in writing before you order, and read the sidewall when the tire lands. The steer axle is the one position where a wrong call is not survivable.

What else it is not. It is not a drive tire: an all-rib tread does not put torque down, and the FM750 or FM770 is the right answer on a drive axle. It is not a winter tire — no M+S branding and no three-peak mountain snowflake — so do not buy it against a chain law. It is not EPA SmartWay verified; neither Invovic nor Firemax appears on EPA’s verified low-rolling-resistance list, so it gives a fleet no compliance path under CARB’s tractor-trailer greenhouse-gas rule and no fuel-economy claim comes with it. Invovic publishes no treadwear warranty, no casing warranty and no named retread program for this pattern, so do not plan on a second life for the casing until your retreader tells you they will take it. And it is built in 295/75R22.5 only. If your steer axle is 11R22.5 — the most common steer size on a US tractor — this tire cannot fill it, and the front axle comes from another brand on the same quote.

The same steer and all-position slot here is covered by Michelin X Line Energy Z, Bridgestone R213 Ecopia, Firestone FS592 and FS591, Goodyear Endurance LHS, Yokohama 108R, Double Coin FR610, CEAT Winmile S and Amulet AT505. Choosing the FM303 instead is a trade you should make on documented terms. A major brand publishes a warranty and adjustment policy with the conditions attached, runs a named retread program its casings are accepted into, publishes dimensional data — overall diameter, section width, revs per mile, approved rims — and lists any third-party verification it has earned, such as an EPA SmartWay listing. Invovic publishes none of that for this pattern. What the FM303 has is a DOT-coded FMVSS 119 casing from the factory we import from directly, with no distributor between us and the plant. Put both on one quote and compare the two all-in numbers, delivered — those numbers come back from us, we do not guess at them here.
