{"product_id":"bridgestone-r123-ecopia","title":"Bridgestone R123 Ecopia","description":"\u003cp\u003eA trailer tire and nothing else. Bridgestone builds the R123 Ecopia for single- and tandem-axle trailers and dollies in long-haul and regional-haul highway service, and the design brief is fuel first. If your trailers roll interstate miles behind a linehaul tractor — van, reefer or dry freight — this is the axle it was drawn for. All four sizes we quote are Load Range G, 14 ply, speed symbol L for 75 mph, on an 11\/32 inch tread: 11R22.5 and 11R24.5 at 105 psi max cold inflation, 285\/75R24.5 and 295\/75R22.5 at 110 psi.\u003c\/p\u003e\u003cp\u003eMost of the fuel work happens in the compound and the sidewall. Bridgestone’s NanoPro-Tech polymers cut the energy the rubber loses as heat every time it flexes. The IntelliShape sidewall runs less bead filler, so there is less mass to heat up to begin with, and a Fuel Saver Sidewall compound carries the gain forward — Bridgestone says it keeps saving fuel both when new and retreaded. The tread belongs to the same package: 11\/32 inch is shallow for rolling resistance first, and what that buys on a free-rolling axle is less block movement, which means less squirm, heat and irregular wear. Cross-Rib Sipes slice through water for grip when the road is wet. Thick ribs on both sidewalls fight curbing damage to protect the casing, and the belt package is built to survive the retread cycle: Bridgestone pattern-matches this casing to the Bandag B123 FuelTech.\u003c\/p\u003e\u003cp\u003eIt is not an all-position tire. Bridgestone’s data book calls it a trailer use only tire, so it does not belong on a steer or drive axle, ever. Yard and spotter work and dock shunting sit outside Bridgestone’s recommended application for this tire. Severe service, on\/off-highway and off-highway work, waste and refuse, mining and logging go further — they void the Enhanced Casing Credit Limited Warranty outright, which costs you the retread value that makes a fuel tire pay. That credit only survives a casing run in long-haul, regional or P\u0026amp;D highway service its whole life. The shallow tread was chosen for rolling resistance, not for cut or scrub resistance. There is no 3PMSF severe-snow rating and no published M+S marking, so do not spec it as a winter tire. And it is Load Range G only: Bridgestone does not build a Load Range H R123 in any of our four sizes, so a fleet that needs 16-ply trailer capacity has to move to another line. Before you order 295\/75R22.5, check the trailer — that size wants 13.2 inches of minimum dual spacing.\u003c\/p\u003e\u003cp\u003eOur own Invovic FM591 does the same free-rolling trailer job from the other direction: a deep 19\/32 to 20\/32 rib design from our factory-direct import line, molded in Cambodia, quoted in 11R22.5, 11R24.5 and 295\/75R22.5 in 16-ply Load Range H only — a ply rating the R123 is not built in, so the two never share a load range. What the R123 brings that the FM591 does not is documentation. It is EPA SmartWay verified and CARB compliant. It carries Bridgestone’s limited warranty for 6 years from the date of manufacture, down to 2\/32 inch, plus an Enhanced Casing Credit on the casing that runs to the end of the retread period on Bridgestone’s table or 7 years from the date of manufacture, whichever comes first, with retreads inspected and retreaded by an authorized Bandag dealer only. It has a named matched retread, the Bandag B123 FuelTech. Bridgestone publishes per-size dimensional data down to the 13.2 inch minimum dual spacing on 295\/75R22.5, and builds the R123 in all four of the sizes we quote against the FM591's three. Its 295\/75R22.5 is documented as built at Bridgestone’s LaVergne, Tennessee plant. For the FM591 there is no SmartWay verification, no matched retread pattern and no casing-credit program published. Bridgestone publishes no mileage warranty on the R123 either — the data book says none is expressed or implied — so judge both on the axle they have to run. Put both on one quote and compare the two all-in delivered numbers side by side; those numbers come back from us.
