Just what the title says. I was wondering if some one could give me height in inches. I'm getting goodyear wrangler authoritys this week.

 

31.6"

 

32" tire

 

~31.5" diameter tire

 

I got those, haven't been let down yet, they do good on road and in some loose stuff, but haven't had a chance for any mud yet. They hum a bit at 60. And they look badass!

My .02

 

Ok I may try to go 285 70 17 then ill just have to check around around on prices.

 

285=33"

 

Remember, the 285 is the width, not height. The aspect ratio, or the 70 in 285/70R17 tells you heigh

 

W (265mm or 10.433in) X Aspect ratio (70% or.70) X 2 + rim size (17")= diameter (31.6")

At least that's the way I was always told.

 

Partially. 70 is the percentage, of the width, which in this case is 285 mms, that 1 sidewall is to the rim.

The overall height therefore is:

285mm * 0.7 x 2 + 17 inches = 32.71 inches when the tire is fully inflated. Yes, you have to convert mm's to inches, or vice versa, and add 2 sidewall measurements.

Here's a good site to use to calculate any othe future tire sizes;
