I purchased a 1969 Mach 1 with oem wheels that I believe are 14x6 with 215x70x14 cooper tires. I have since purchased Coker Magnum 500's with 235x60x14 on 14x7 rims. Back space on the oem is approx 4.25. The magnums are supposed to be also 4.25. I measures them and appear to be 4 3/8 " ? My purchase was based on what I had read others had done. My front tires rub (not rims) the upper ball joint a-arm? It is a disc brake car and everything is original. What I did not realize before was even the oem wheels and tires are a little close to this also. What I am learning a bit late is overall tire width, backspacing, and height are an issue with the front. My question is would anyone know if I changed the front tires only to a 215x60x14 or 225x60x14 using the same 14x7 magnums would I gain 1/2 inch or more clearance. Any suggestions wpuld be appreciated. I would like to stay with 14 inch rims,but if the only way is to move up to 15" I have 4 brand new set of never used w & t that I'm not sure what to do with.
