Know what I wish there was? A website where you could input the Revolutions Per Mile you want to match, then it would find you a size closest to that that actually exists
I need to match 720 RPM(ile) as the current spec for the truck and the original tire size for the wheel I'm putting on the truck was 295/45R18. 275/50R18 is 721 RPM. As close to perfect as I can find. Doesn't exist as a tire.
295/45R18 isn't bad, 730 RPM, but the guy that had the wheels before me put on something like 275/55R18
Seems like awfully short sidewalls for a truck. Unless I guess it doesn't really get used like a truck?
