My sons 57 GMC 100 NAPCO w side mount and optional 17.5“ wheels has the tire mounted in its original location using 8.00-17.5 tires. We stumbled on these slightly used tires for a great price, and luckily the spare barely fit (I used my hand to tap it into the fender as I tightened the lug nuts) but it rides there.
