{"title":"ST225\/75R15 Trailer Tires","description":"\u003cp\u003eST225\/75R15 is the standard 15-inch tire for tandem-axle travel trailers, car haulers, enclosed cargo trailers and larger boat trailers. It is also written as 225\/75R15, 225\/75D15 or 225\/75-15 and measures about 28.3 inches tall and 9 inches wide. The ST prefix means Special Trailer: a stiffer sidewall built for towing loads, not for a truck or SUV.\u003c\/p\u003e\u003cp\u003eWe carry it in load range D (8-ply, about 2,540 lbs per tire) and load range E (10-ply, about 2,830 lbs per tire), in radial (R) and bias-ply (D) construction, including the Goodyear Endurance. Match the load range on your current tire or the trailer's capacity sticker, and never go lower. Orders ship from the U.S. with tracking.\u003c\/p\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eD or E load range for my camper?\u003c\/strong\u003e\u003cbr\u003eMost tandem-axle campers under 7,000 lbs ship on load range D.
