A 285/70R17 works out to 32.71″ on paper, but the 36 tires we have in that size are listed at up to 33.15″ by the companies that make them. Look up a size to see each tire's listed height, weight and tread depth from BFGoodrich, General, Michelin, Mickey Thompson and Toyo—and whether it's really a 33 or a 35.
