Looking for a source on Whitewall Tires to fit on my stock rims, which I believe are 16.5" dia. I've looked at a lot of pictures showing restored trucks with "thin stripe" white wall tires. Are these available for the 16.5" rim, or have they switched to a different size rim. The truck I just bought '62 1/2 ton has 245/75r16 on it, which I've been told is a NO NO! Any help would be appreciated.
