Lol terry that wasn't really the question...

X2 on a 10.50. Anything wider than that and you're REALLY ballooning the tire out.

what do you mean im kinda confused, dont know much on tires really. what does the 10.50 mean the width? is that what the chart was for 10.50 width tires clearance?

what im aiming for is a tire where the tread is wider to make her corner better

10.50 is your tire width ie- 31x10.50x 15 tire height x tire width x rim size

Default Re: Tire width help

heres the best way i can explain using a 265 compared to a 31/10.50.15

265 millimeters is section width, the widest part of the tire halfway up the sidewall. 75 means that the sidewall is 75% as tall as the section width. So the sidewall is 75% of 265, or 199 millimeters tall. Two sidewall heights plus the rim height will give you the height of the tire, or 2*199 millimeters + 15 inches. 398 millimeters divided by 25.4 millimeters per inch = 15.65 inches, + 15 inches = 30.65 inches. And 265 / 25.4 = 10.43 inches of section width. So it's a 30.65 x 10.43R15, although due to the undersizing involved in tire sizes it usually ends up identically to a 31x10.50. The wierd part is, since rim size comes into account in the height of a metric sized tire, flotation sizes like 31x10.5R15 and a 31x10.5R16 would be the same height, but a 265/75R16 is an inch taller than a 265/75R15.


10.50 would be a metric width( metric goes tire height--tire width--rim size)
standard would go width--sidewall height--rim size

the standard measurements often confuse people because they think of a 31" tire where the height is the first number so they immediately think a 265 =height.

----------

and in all truth as i mentioned-metric sizes are often undersized. if you actually measure a 31,33,35 etc they are usually about .2" shorter

----------

and for cornering you may want to upgrade your shocks. often overlooked

ok thanks for the info ill have to think this all over

----------

ok so if i wanted to keep the same height and rim tire, and wanted it to be wider, i would get one that had close to the same middle number(75) and get one with a higher first number (235) ???

thanks for dealing with me

if you want wider and the same height you need to go with a different sidewall ratio(the middle number-75-)

For example a 245-70-15 is the same height as a 235-75-15

Then a 255-65-15....etc
