{"title":"ST175\/80R13 Trailer Tires","description":"\u003cp\u003eST175\/80R13 is the standard 13-inch trailer tire, found on small utility trailers, jet ski and personal watercraft trailers, pop-up campers and light boat trailers. It is also written as 175\/80R13, 175\/80D13 or 175\/80-13, and measures about 24 inches tall and 7 inches wide. The ST prefix means Special Trailer: a stiffer sidewall built for towing, not for a car.\u003c\/p\u003e\u003cp\u003eWe carry it in load range C (6-ply, about 1,360 lbs per tire) in both radial (R) and bias-ply (D) construction. Match the load range on your current sidewall or the capacity sticker on your trailer, and never go lower. Every order ships from the U.S. with tracking.\u003c\/p\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWill a 175\/80R13 fit my 13-inch trailer wheel?\u003c\/strong\u003e\u003cbr\u003eYes, as long as the wheel is 13 inches in diameter and 4 to 5 inches wide.
