{"product_id":"firestone-fs591","title":"Firestone FS591","description":"\u003cp\u003eThis is the steer tire a lot of highway fleets are already running. Firestone builds the FS591 for on-highway steer work — long haul, superregional and less-than-truckload running — and files it as an all-position radial, so it is cleared to run back on a drive or trailer axle as well. Firestone’s own line on it is an innovative sidewall design that reduces overall weight for increased mileage and better fuel efficiency, and that is what earns it EPA SmartWay verification and CARB compliance. We quote it in all four of our sizes: 11R22.5 and 11R24.5 in Load Range G and H, 285\/75R24.5 in G, and 295\/75R22.5 in G and H.\u003c\/p\u003e\u003cp\u003eThe tread is a five-rib highway pattern, and the detail work is aimed at the two things that kill a steer tire — irregular wear and heat. A continuous shoulder helps reduce rolling resistance. Cross-rib sipes slice through water for grip on a wet road. Stress relief sipes fight irregular wear along the main ribs by absorbing edge stresses in the footprint, which is the feathering and cupping you feel through the wheel long before you see it. Every size runs 18\/32 inch of tread and speed symbol L, 75 mph. Weights run 116 lb in 11R22.5, 123 to 124 lb in 11R24.5, 122 lb in 285\/75R24.5 and 114 lb in 295\/75R22.5.\u003c\/p\u003e\u003cp\u003eWhere it sits against the FS592 is worth being straight about, because we sell both. Firestone launched the FS592 in October 2025 as this tire’s successor, with 19\/32 of tread against this one’s 18\/32 and a claim of 17% longer life. The FS591 is not discontinued — Firestone’s own product feed still lists all seven of the articles we quote in production status — and it is the tire a fleet with an existing spec, an existing casing pile and an existing retread contract usually wants to keep buying. If you are starting fresh and want the deeper tread, ask for the FS592 on the same quote.\u003c\/p\u003e\u003cp\u003eWhat it is not. It is not a drive tire in practice: an all-rib steer pattern will not put torque down the way a lugged drive does, so the tandem takes the FD692 or another drive pattern. No three-peak mountain snowflake severe-snow rating is published for it, so a chain-law lane deserves a tire that carries the symbol. And the warranty has edges. Firestone’s base limited warranty runs six years from the date of manufacture down to 2\/32 inch, with no mileage warranty expressed or implied, and the Enhanced Casing Credit tier that pays on the casing requires the tire to have run highway service — long haul, regional or pickup-and-delivery — for the whole life of the casing, with inspection and retreading by an authorized Bandag dealer. Quarry, log-road and mining work sits outside that tier. Check the load range against your axle too: 285\/75R24.5 comes in Load Range G, 14 ply, only.\u003c\/p\u003e\u003cp\u003eIf what you need is the axle covered and not the program behind it, the Invovic FM303 is the factory-direct alternative on this store — our own import line, steer and all-position, in 295\/75R22.5, 16-ply Load Range H only. The comparison is short. The FM303 runs 14\/32 of tread against this tire’s 18\/32, it is built in one size where the FS591 covers all four, it carries no EPA SmartWay verification and no CARB compliance statement, and Invovic publishes no casing warranty and names no retread program. What it has is the same DOT-coded FMVSS 119 job on the axle, imported by us with nobody in between. Put both on one quote and compare the two all-in delivered numbers when they come back — tires, delivery, tax and the state tire fee in one figure. Mounting and balancing is your local truck tire shop’s charge, on their invoice.\u003c\/p\u003e","brand":"Firestone","offers":[{"title":"11R22.5 \/ 14 Ply (G)","offer_id":53707594268948,"sku":"FIRESTONE-FS591-11R22-5-14","price":0.0,"currency_code":"USD","in_stock":true},{"title":"11R22.5 \/ 16 Ply (H)","offer_id":53707594301716,"sku":"FIRESTONE-FS591-11R22-5-16","price":0.0,"currency_code":"USD","in_stock":true},{"title":"11R24.5 \/ 14 Ply (G)","offer_id":53707594334484,"sku":"FIRESTONE-FS591-11R24-5-14","price":0.0,"currency_code":"USD","in_stock":true},{"title":"11R24.5 \/ 16 Ply (H)","offer_id":53707594367252,"sku":"FIRESTONE-FS591-11R24-5-16","price":0.0,"currency_code":"USD","in_stock":true},{"title":"285\/75R24.5 \/ 14 Ply (G)","offer_id":53707594400020,"sku":"FIRESTONE-FS591-285-75R24-5-14","price":0.0,"currency_code":"USD","in_stock":true},{"title":"295\/75R22.5 \/ 14 Ply (G)","offer_id":53707594432788,"sku":"FIRESTONE-FS591-295-75R22-5-14","price":0.0,"currency_code":"USD","in_stock":true},{"title":"295\/75R22.5 \/ 16 Ply (H)","offer_id":53707594465556,"sku":"FIRESTONE-FS591-295-75R22-5-16","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1025\/9107\/0484\/files\/firestone-fs591_89d4f352-006e-4a57-861d-d935bf57748d.png?v=1787425294","url":"https:\/\/aurextire.com\/products\/firestone-fs591","provider":"Aurex Tire Co.","version":"1.0","type":"link"}
