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.
