Wrong 225 80 18225's are on my stock zj. They are the overall size of the tire, yes they'll fit. 80 is the width, the tire is 80% of the 225 size and 18r is your rim size (denoted by the "r") . You have to have 18" rims with the proper bolt pattern to put those tires on and then on your jeep, but if you've made it that far, then yes they will fit. If you have any problems, wheel spacers will probably make them fit, without cutting anything, depends on the look your going for. Always check rubbing and clearances to wires, cables, brake lines, fender, wheel well...I've ripped off some stuff with my tires before.
