Re: My Dusty 71 GMC a Mother & Son Project
Alright folks, time to do some tire size math
our new rims are 17x8" so first 8" is 203 millimeters (that gives us a reference)
second 215 is the minimum tire width recommended for an 8" rim
third our stock wheels are 235/75R15 which computes to a 28.9" diameter so essentially we are currently running 29" wheels
if we were to keep the same wheel height we would need to get a 215/70R17 set of tires which is an odd size and not very popular therefor expensive
so we step it down a notch to a 215/65R17 tire size which ends up being a 28" tall wheel and so be it, there is a huge selection of tires in this size
GOOD YEAR
