Herse a few pics of my truck with 18's, the sidewall of the tires are 55.




You sure I thought it just measured the heght of the tire? Well thye are 255/55/R18's anyways.Herse a few pics of my truck with 18's, the sidewall of the tires are 55.
you saying that the sidewalls are 55 doesnt mean anything unless you give the width as well...55 of a 235 is alot less then 55 of 275!
yup, he's right. incase you didn't know, the middle number is a percent of tread width.
when they say a tire is 255/55/18, that means:
255 = tread width in millimeters
55 = sidewall height, as in, 55% of 255
18 = rim size.
so, a 255/55/18 is 29" tall, with a sidewall height of only 140.25mm and a 235/55/18 is only 28.1" tall, with a sidewall height of only 129.25mm.
Good to know, thanks for the info rainman.:jester:
