The rims and tires on my 1966 LeMans are too big. I don't want to modify anything and I'm wondering about the largest rims and tires I can install. The car has been updated with disc brakes. I am thinking that I can put on 16x7 rims with zero offset and 4-in backspace. I am looking at 16-in 235/50 tires. I would certainly appreciate comments about how this might fit on a standard height suspension system and no modifications to wheel wells. Thanks in advance!
