Wheel and Tire Help

15x7 front wheels will work but you need at least 4.25 B.S. FYI, all factory Chrysler 15x7 wheels were produced with 4.25 B.S. Look for a wheel with a minimum of 4.25 B.S. 4.5 even better.(positive offset) As already mentioned, consider a 215/60x15 front tire. Your main point of interference is the lower corner of the fender opening right in front of the tire. You generally need to stay under 26" outer diameter and your dad's suggestion of a 70 series could be too tall.

Cragar wheels have always been biased towards GM cars (lowest common denominator) which is why you have to be careful as they usually do not fit Mopars.

Your rear bolt pattern is probably the factory 5 on 4". Good luck with that. Far less selection unless you convert to 5x4.5.
