the bolt pattern on the rims is 5x5 1/2. many different vehicles have used that same bolt pattern. f-150s, broncos, dodge halfton trucks, some jeeps. the f-150 and bronco rims need to be machined out a little to fit, i know jeeps and dodges work without any problems, my spare is one. if you are looking for some bigger tires and rims, contact jaybur on this site. has some chrome rims with four new tires that are 30x9.5 on it cheaper than anywhere you can get em new. he is great to do buisness with. if you want new rims jegs.com and summitracing.com have cragars for under $40 a rim and free shipping. i swapped from stock tires and rims to some chrome cragars and 225/75 all terrains. no rubbing, no power loss. did lose some pretty serious mpg though. went from 18-20 to a solid 13.5 <img src="/forums/images/graemlins/barf.gif" alt="" />
