I bought some new rallye II wheels for my 69 gto convert. The ones that were on it when I bought it were the dog dish style and were completely roached. The tires were also dry rotted. The sizes I picked are for the fronts I bought 15x7's and for the backs I bought 15x8's. My gto originally had red lines on it from the factory but I do not have the funds to buy such expensive tires at this moment. So what I am wondering is what size tires would fit nicely for the fronts and backs? Is there a standard size people use for 15 inch rims on gto's. Thanks in advance guys.
