Best tire size
Hi everyone:
I put on a new 15" steel wheels on my 66 F100 ( came off 93 Ford F100), I wonder what is the best tire size to use that will not effect on speedometer reading?. Thanks

Aspect ratio is the height of the sidewall compared to the section width. This is all pretty nominal, as I doubt you'd find any tire that's exact.
So a 70 series tire has a sidewall that is 70% of the section width measurement. A 75 is 75%, so it will be taller. A 60 is 60%, so it will be shorter.
More info--in fact, total information overload--available here:
