Tire Size Question
I have a 2005 Z71 4X4 with 265/75R15 tires. I have had great wear and tear on the tires, 178,000 miles and only 1 tire change. My issue is at this tire size there is a very small section of tires and tread types available. I used an online tire calculator and it seems tires sized at 31/10.50X15 are just slightly larger and wider then the original. No more then a 1/4" either way.
Has anyone put this size tire on the stock rims and had any issues or is it a good fit?
Thanks for the help.

I haven't seen 15 inch rims in a long time, 16 was the standard for a while. I checked TireRack.com for the size you have and only 8 results came up, which is low.
On the other size I think you are missing a number at the beginning. It looks like there were 2 options from GM for your truck from the factory:
245/75R16 or 265/70R17. There are allot more options at those sizes. Could you take a picture of the tire/rim so we can see the numbers on the tire?

The 31s are smaller height wise than the 265/75s. The 265/75s measure up at about 1/4 inch under 32 inches at 35PSI....at least thats what my Coursers come in at.
If at first you don't succeed, chances are, you are using too small of a cheater bar

Hello. I just put 31 x 10.50's on my 05 Z71 yesterday. I assure you they will fit on the stock rims with no issues what-so-ever. They look a lil larger/taller than the stock 265/75's. Hope this helps!

15 inch rim on a 2005 Z71 Colorado/Canyon doesn't seem right, did you buy this new? Or used and somebody put a different rim on it?99 K1500 Suburban LT "THE BEAST"
