These great NCAA tire covers are made with a heavy gauge vinyl that has an elastic tie down for an easy fit. It is a universal fit tire cover that fits tires that are 27"-29" in diameter, and up to 10" in thread width. It's also water resistant, and wipes clean with a damp cloth. Please note: Unfortunately, this tire cover does not fit wide tires or some all-terrain tires due to tread size. Please measure your tire before installing to ensure proper fit.
