I have a 2001 Jeep Grand Cherokee with 16” rims, got a set of 15s to put on but with the caliper they won’t fit. What size of wheel spacers and length of studs would I need to adapt them? Or does anyone have a recommendation for where to find the whole adapter kit at a good price? First Jeep and only my second car, still have a lot to learn so please be kind if I’m asking a dumb question. Tires I want to put on are 235/75R15, aluminum rims. Got them from a buddy who doesn’t need them and mine are going bald, don’t have money to afford a set of tires anywhere so looking for a way to get these to work if possible. Any advice is greatly appreciated. If there’s any more info I can add let me know. It is a two wheel drive, don’t know if that changes anything.
