It fits on the stock 265/70r17 size tires. The tires that came with the FJ were the Bridgestone Dueler H/T D840 series (I believe the exact dimensions were 31.7 inches tall and 10.5 inches wide and 17 inch Rims). It should fit most tires in that size. Most of the OEM spare tire covers I have seen are made the same. This one has a hard outer shell with soft leathery sides that stretch around the spare tire with elastic.
