When it comes to Jeeps one of the most common questions asked is, “What size tires can I fit on my Jeep?" If you have asked that question or if you intend on putting larger tires on your Jeep you should give this article a read. It will help you make your decision on what tire to buy for your stock Jeep.
There are three models of Jeep Wranglers, the YJ, TJ and JK. The YJ which were made between 1987 and 1995 are best identified by the square headlights and leaf spring suspension. If you have a YJ your best bet without a lift is a 30 x 9.5 inch tire. Next there is the TJ which was made from 1997 to 2006. TJs are identified by the return to round headlights and is the first model to use a coil spring suspension. They have a little more clearance so you can therefore go with a 31 x 10.5 inch tire with no problems. You might have to adjust the steering stops if you keep the stock wheels biut that is an easy procedure. (Do a search for “jeep steering stop adjustment"). Finally you have the newest JK version which were built between 2007 and the present. JKs have an even larger wheel opening as well as an increased wheel base and slightly wider stance. JK's can easily run a 32" tire and even a 33" tire with the right wheels.
So there it is. Those are the basic tire sizes you can fit on stock Wranglers. Of course you should use this as a general guideline only. Consult a tire professional before investing the money in wheels and tires if you are unsure about what tire will fit.
