gotta ask......one more tire question

Going to subject myself to ridicule on this but I have to ask. I have a 2010 sport and want to replace my tires with the biggest tires and or rims that I can without a lift (lift will be forthcoming when money permits) so I've been reading the threads about tires but I know nothing about back spacing and when people refer to 33, 32, 40 ect. So I was looking for an explaination on those two topics and suggestions on sizes, brands, ect. I've seen a lot of good comments on the Goodyear with Kevlar so I was kinda leaning towards them. Right now i only go on some class4 roads that can incluse going over sone rather large rocks (not boulders) Thanks for taking the patience to reply!

well... the tire sizes are in japtalion...

I'll use my size as an example, and yours might be the same or different...

P225 75-16

The P is the tire type... "passenger" I think. (not important)...

225 is the tire width, in millimeters ("you know why they call it a royale wit cheese?")

75 is the "aspect ratio", it's the height from rim to tread, and If I understand it correctly, it's a percentage of the width. (so a 10 inch wide tire with a 60 AR should be 6 inches rim to tread)

The 31, 32, 35 you see posted, usually with a " by it, are overall height, in inches. There are 1.134 million converters you can google

If your tire size is the same as mine, P225 75-16, Then I'd recommend sizing the MT/R's at 235/85R16, a size they do make, which are 32" tires (supposedly! actual sizes vary..) and aren't too wide, so you have very little chance of having any issues with the fit, but do some homework before you make the call

Mine will wind up being a little bigger, but I have no problem taking a sawsall to my fenders

Dont know if it will help but here are some common conversions\sizes just to give you a idea.

245/75/16= 31's
265/75/16= 32's
285/75/16= 33's

You have the stock steel wheels? Don't want to replace them? I just upgraded my pizza cutter tires to the Goodyear Duratrac 245/75 16 - they look fantastic. ride is much improved too.

oh yeah... rims...

If you're planning on rims with new rubber, then I'd say go to a shop and explain exactly what you're trying to do... rims have backspacing that affects what will rub too

on stock rims, try to keep it a little skinny if you can... in addition to the height of the tire causing your fenders to hit, wider ones can cause you to hit the frame on the inside when turning...

Shouldn't rub... That's roughly a 10.5x32" tire, which is just about .5" wider and a hair shorter than the stockers on a Rubi....
