Tire Size?

[HarlanC]

I realize there are a couple thread about this already but I guarantee you mine is different. I've got a 1991 GMC Sierra 1500 two wheel drive. I've got the stock 15" rims and Im wondering how much rubber I can fit. I've got 235/75/r15 on there now and I still feel I need more tread to make it look nice. Only suspension mod Im thinking of doing is lowering the back end 2" to level it out.

If you are sticking with 15 inch OEM wheels, most people went with a 255-70-15 back when those trucks were new to get a little more tire in the wheelwells. 30x9.50x15 all terrains fit as well. 31x10.50x15 will work but they will occasionally hit the top of the fenders when turning and hitting bumps.

Thank you kindly. Now I just need some damn good luck to find some used ones haha. I guess everyone and their brother has a truck around here!
