{"product_id":"double-coin-ft115","title":"Double Coin FT115","description":"\u003cp\u003eA free-rolling trailer tire for line-haul work — the axles that carry the load, take the scrub in the yard, and are never asked to pull or steer. Double Coin builds the FT115 for long-distance hauling and lists it as EPA SmartWay verified, crediting an advanced fuel-efficient compound with the improved rolling resistance. It has the widest size coverage of any trailer tire we quote: 11R22.5 and 11R24.5 in Load Range G and H, 285\/75R24.5 in G and H, and 295\/75R22.5 in G — seven builds across all four sizes.\u003c\/p\u003e\u003cp\u003eThe tread is shallow by design at 13\/32 inch. That is not a shortcoming on a trailer axle, it is the point: less rubber under the belts means less heat and less rolling resistance, which is where a fuel-focused trailer tire earns its keep. For reference, the Michelin X Line Energy T2, Bridgestone R123 Ecopia and Firestone FT492 all run 11\/32 and the Yokohama BluEarth 109L runs 12\/32, so the FT115 sits at the deep end of the fuel-trailer class. If what you want is maximum removal miles instead, the deep-tread trailer tires on this store are the Goodyear Endurance RST at 18\/32 and our own Invovic FM591 at 19\/32 to 20\/32.\u003c\/p\u003e\u003cp\u003eStone ejectors sit in the grooves to push trapped rock back out before it works toward the belts, and there is extensive siping across the ribs to spread edge stress and hold off the uneven wear that trailer scrub causes. Double Coin publishes a full spec table, so the dimensions and fitment table below is filled in with overall diameter, section width, revs per mile, static loaded radius, measuring rim and the product code for every build. Note that two of the Load Range G builds carry speed symbol M, 81 mph, and the rest carry L, 75 mph.\u003c\/p\u003e\u003cp\u003eWhat it is not. Trailer axles only. Do not let a shop put it on a steer, and it will not pull on a drive axle — Double Coin’s answers there are the FR610 and the FD405. It carries no three-peak mountain snowflake marking. There is no mileage warranty; the coverage is a limited warranty against defects plus the seven-year, three-retread casing program.\u003c\/p\u003e\u003cp\u003eThe comparison worth making is against the majors' verified trailer tires, because that is the same job with the same badge on the fuel question: Michelin X Line Energy T2, Bridgestone R123 Ecopia, Firestone FT492 and Yokohama BluEarth 109L are all SmartWay verified too. Where they pull ahead is the retread channel — MRT for the Michelin with named matching patterns, Bandag B123 FuelTech for the Bridgestone and Firestone — and the depth of published substantiation behind the fuel claims. The FT115 answers with 2\/32 more tread than most of them and coverage in 285\/75R24.5 Load Range H, which several of them do not build. Put both on one quote and compare the two all-in delivered numbers.\u003c\/p\u003e","brand":"Double Coin","offers":[{"title":"11R22.5 \/ 14 Ply (G)","offer_id":53707595219220,"sku":"DOUBLE-COIN-FT115-11R22-5-14","price":0.0,"currency_code":"USD","in_stock":true},{"title":"11R22.5 \/ 16 Ply (H)","offer_id":53707595251988,"sku":"DOUBLE-COIN-FT115-11R22-5-16","price":0.0,"currency_code":"USD","in_stock":true},{"title":"11R24.5 \/ 14 Ply (G)","offer_id":53707595284756,"sku":"DOUBLE-COIN-FT115-11R24-5-14","price":0.0,"currency_code":"USD","in_stock":true},{"title":"11R24.5 \/ 16 Ply (H)","offer_id":53707595317524,"sku":"DOUBLE-COIN-FT115-11R24-5-16","price":0.0,"currency_code":"USD","in_stock":true},{"title":"285\/75R24.5 \/ 14 Ply (G)","offer_id":53707595350292,"sku":"DOUBLE-COIN-FT115-285-75R24-5-14","price":0.0,"currency_code":"USD","in_stock":true},{"title":"285\/75R24.5 \/ 16 Ply (H)","offer_id":53707595383060,"sku":"DOUBLE-COIN-FT115-285-75R24-5-16","price":0.0,"currency_code":"USD","in_stock":true},{"title":"295\/75R22.5 \/ 14 Ply (G)","offer_id":53707595415828,"sku":"DOUBLE-COIN-FT115-295-75R22-5-14","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1025\/9107\/0484\/files\/double-coin-ft115.png?v=1787425312","url":"https:\/\/aurextire.com\/products\/double-coin-ft115","provider":"Aurex Tire Co.","version":"1.0","type":"link"}
