18" wheels on a Dakota?

Some salesperson was trying to shy me away from getting 18" wheels. He didn't think that it would look good. I'm pretty sure there would still be a good amount of tire on there.

Can I see some 18" wheels?

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!
You sure I thought it just measured the heght of the tire? Well thye are 255/55/R18's anyways.
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:
