I have a 74 Road runner that currently has 205/70/r14 and 245/60r14 tires on crager wheels. The tires are getting old and they also look tiny in the wheel well so I want to upgrade to something bigger. When I bought the car it came with a set of 15" rallye wheels (perhaps original?) that I'm going to use. Fronts are 6.5", rears are 7". I want to find a tire that will fill out the wheel well the best. I'm thinking either 235/60r15s or 235/70r15s for the front and 255/60r15s or 255/70r15s for the back. Cooper cobra gts. Any know if I can fit the 70s. I see that drop top got them to fit on his 71 so I figured it would work on my 74.
