Tire Size Calculators

thnx dude i really need this calc

thanks, i quoted and posted on our car club forums.

helpful link thanks

Great post. Just what I was looking for.

In a bind and don't have web but have a calculator.

for a 265-70R16

265 is width in mm (convert to inches by dividing 25.4) = 10.43
70 is the percentage of the width that is the side wall height (10.43 * .70) = 7.3
Diameter of the wheel + 2 sidewalls (7.3 * 2 + 16) gives the overall height. = 30.6

Will use thanks.

Great web site will use it. Thanks.

thats reallly great info...could really use this in the future

Red Rock 4x4 is no longer in business and has no information at the listed address.

Great Find. But. Heres the question? Will the computer have to be recaled? I just bought a 09 Sierra. Wanna go from 18's to 22's.

Great Info!
