70-72 Tire size chart

I found this while surfing, thought I’d pass it along. It has alternate tire sizes from 14-20” wheels, and tells you how close in size to oem, in order to keep your speedometer accurate.

Thanks for posting this! It should come in VERY handy!

 

The “very wide tire!!” Made me laugh. Seems like a great reference site though.

 

Yeah, made me laugh too. 275’s are not “very” wide in my opinion. My daily runs them at all 4 corners, haha!
