Thanks, great to be here!
4wd, mostly street use with minimal off road use but I know he wants an AT tire. I am leaning toward something like Firestone Destination AT or General Grabber 2, etc. Keeping the stock rims and looking to definetely increase the width and possibly the height but its not important as the width.2WD or 4WD? Road use, off-road use or both? Street tire or off-road tire? Will you keep the stock wheel size or are you looking to increase the diameter and/or width?
285/60/18 should be fine inside the wheel wells. I'll measure mine tomorrow and let you know what I come up with.
