Tires sizes for a 1970

We just got a set of American Racing Thrust II rims for the Grand Ol' Lady (1970 Convert) We got 16 X 8's for the front and 17 X 8's for the rear. Any suggestions on tire sizes? We want something a little lower profile but not radical. Kind of keep it similar to the original height. We are thinking of 245/45 17 for the rears. Any prpblem with this size??? What about the front?

Thanks, Jim

F70-15s stock on a '70? If so, stock diameter is 27". 245/45/17 is about 25.7". 17" wheels and a low aspect ratio (0.45) will stiffen up the ride. 255/50/17 is 27" and has a little more rubber on the ground and a little more sidewall. That's what I'd do on the rear.
