{"product_id":"invovic-fm591","title":"Invovic FM591","description":"\u003cp\u003eA trailer-axle radial for van, reefer and flatbed work, in three sizes — 11R22.5, 11R24.5 and 295\/75R22.5 — every one a 16-ply Load Range H casing. It runs behind the tractor on regional freight, drop-yard shuttles and tight-dock loads — the axles that carry weight and take scrub, and are never asked to pull or steer.\u003c\/p\u003e\u003cp\u003eDepth is the argument for this tire. It carries 19\/32 inch of tread in 11R22.5 and 11R24.5 and 20\/32 in 295\/75R22.5. The line-haul fuel trailer tires we quote — Michelin X Line Energy T2, Bridgestone R123 Ecopia, Firestone FT492 — run 11\/32; the Yokohama BluEarth 109L runs 12\/32; Double Coin FT115 runs 13\/32; the deep-tread specialist in the class, the Goodyear Endurance RST, runs 18\/32. That extra rubber is removal miles and scrub tolerance: more to give up in the yard and at the dock before the tire comes off the trailer. What you pay for it is rolling resistance — a deep tread is not a fuel tread, and Invovic publishes no rolling-resistance figure either way, so we make no fuel claim in either direction.\u003c\/p\u003e\u003cp\u003eThe tread is five ribs split by four wide circumferential grooves that push water out from under the footprint. S-shaped sipes cut across the ribs to add biting edges on a wet road and to let the rubber shed heat. Decoupling grooves at the shoulder let the outside rib flex a little on its own. Stone ejectors sit in the four main grooves to kick rocks out before they drill toward the belts. Every size is 16-ply Load Range H at 120 psi — there is no 14-ply Load Range G build — rated 6,005 lb dual in 11R22.5 and 295\/75R22.5 and 6,610 lb dual in 11R24.5.\u003c\/p\u003e\u003cp\u003eWhat it is not. It is not a steer tire. Invovic publishes no steer or all-position rating for this pattern, and the steer axle is the one place a tire failure is not survivable, so we quote it for trailer axles only — do not let a shop mount it up front. It is not a drive tire either; ribs do not dig. It is not EPA SmartWay verified: Invovic does not appear on EPA’s verified low-rolling-resistance list, so it cannot go under a 53-foot box trailer operating in California under the state’s tractor-trailer greenhouse-gas rule. It is not made in 285\/75R24.5, so a trailer running that size takes a different brand — say the word and we will quote one. And if you run a casing program, look elsewhere: there is no published Invovic casing warranty and no Invovic retread program, so plan on this casing having one life until your retreader tells you otherwise.\u003c\/p\u003e\u003cp\u003eThe benchmark for the same duty cycle is the Goodyear Endurance RST — an 18\/32 inch regional and spread-axle trailer tire, marked by Goodyear for trailer use only, listed by Goodyear in all four sizes we quote. What the RST documents, the FM591 has nothing to answer with: a published casing warranty that covers the casing, not the tread, good for unlimited retreads for seven years from the casing DOT date when the retreading is done by a Goodyear Authorized Retreader, and for the first retread only across those same seven years when it is not; a named retread pattern to send that casing back as, Goodyear UniCircle Endurance RST; and a published dimensional table you can hand a fleet auditor. Against the RST you give up all three, and gain 1\/32 to 2\/32 of tread. Load capacity does not separate them: in the three sizes both are built in, each is 16-ply Load Range H with the same service description. Neither tire is EPA SmartWay verified, so if fuel economy is the target, the verified trailer tires we quote are the Michelin X Line Energy T2, Bridgestone R123 Ecopia, Firestone FT492, Yokohama BluEarth 109L and Double Coin FT115. What the FM591 gives back is the same trailer-axle job, factory direct, from a plant we import from with no distributor in between. Put both on one quote and compare the two all-in delivered numbers.\u003c\/p\u003e","brand":"Invovic","offers":[{"title":"11R22.5 \/ 16 Ply (H)","offer_id":53673329623316,"sku":"INVOVIC-FM591-11R22-5-16","price":0.0,"currency_code":"USD","in_stock":true},{"title":"11R24.5 \/ 16 Ply (H)","offer_id":53673329688852,"sku":"INVOVIC-FM591-11R24-5-16","price":0.0,"currency_code":"USD","in_stock":true},{"title":"295\/75R22.5 \/ 16 Ply (H)","offer_id":53673329787156,"sku":"INVOVIC-FM591-295-75R22-5-16","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1025\/9107\/0484\/files\/invovic-fm591.png?v=1789405842","url":"https:\/\/aurextire.com\/products\/invovic-fm591","provider":"Aurex Tire Co.","version":"1.0","type":"link"}
