Is there a website that would help me figure out which size tire will fit on my 72 Riv when I change over to 15 x 8 wheels? The original size was H78 15, now using 222/75 15. I want to keep the same diameter tire, just find a size that fits the wider wheels.
the 225 75 R 15 will fit the wider wheels too. If you want wider tires, you can use 245 70 R 15 or maybe 255 65 R 15. Thy are both very simular. Here you can calculate your tire diameter, so you can try to find that tire you wanna have http://1bad69.com/calc.htm Juergen
the 225/75 is a 28 in tire OK for the 8 in rim. you can also use a 235/70 at 28 in dia or a 275/60 at 28 in dia. The 275 will fit with no clearance problems
