Hey guys. Winter is here and I need new tires. Looking at Wrangler Duratracs but had a quick question.
Currently have p265/65r17's on my 2002 SE.
Was thinking of going to p265/70r17's so plus 5 aspect ratio.

What are the advantages/disadvantages if any? Would I have to do any fender trimming going from 65-70 aspect ratio? Is it worth it? I have no lift kit everything is stock.

Thanks:)

The way you figure this out is as follows:

1) The 265 means the SIDEWALL SECTION WIDTH (Not the tread, the fattest part of the sidewalls) is 265 mm. 265 mm is ~ 10.4" (~ 25.4 mm per inch)

2) The Aspect Ratio is the Sidewall HEIGHT as a percentage of the section width...so an aspect ratio of 65 means 65% of 265 mm, or ~ 6.76 "

3) The rim size (17") is of course merely the size of the hole in the middle of the rim.

4) So, the overall diameter of the tire is, starting at the ground for example, a sidewall height, plus the rim diameter, plus another sidewall height. (2X the sidewall height plus the rim diameter)

So, 17" plus 13.5" = 30.5" tire diameter, so, a nominal 31x10.5/15 equivalent tire...for a 265/65/17 tire.

------

The 265/70/17 would work out to the 265 x .7 or ~ 185.5 mm, or ~ 7.3" of sidewall height.

17" + 14.6" = 31.6" of total tire diameter.

That's closer to a nominal 32x10.5/15 tire.

As that is a 32" or smaller tire, it will fit a stock X of your year with just some snipping off of wheel well plastic...most of which is the wee ledge the front lower mudflaps used to screw into.

As the flaps break off if off road anyway, you don't need the little ledge they screw into.

Its all in the well and doesn't show, so its a popular way to fit 32's.
