I am getting the american racing wheels ar23 wheels 8" on back--7" on front and cooper cobra gt's 275 60/15 on back and 235/70/15 on front.does any one have a combination like this? should I go bigger on front?I have 14" wheels and tires now with drum brakes.I am putting disc on front. will the
7" be ok or can I go with 8 all the way around? Oh yeah Ive got a 67 chevelle--thanks Danny

The 7" front will give a more balanced look with the narrower tire (i.e. sidewall bulge will look similar to rear wheels given sizes you have chosen)...

I had the 275 60's on mine and thought they were a little tall but still looked good
I have 275 50's now and they look great but my 68 is lowered all the way around
