Ok so I'm due for a new set of rubber. How big can I go. I have a '97 Dak Sport 4x4 with a stock ride height and stock rims. My current tire size is 31x10.5x15. Could I feasably fit a 33x10.5x15 on my truck or maybe even some 35x12.5x15's on there?

Thanks

 

There's no way you're going to clear a 35, and I doubt a 33 will fit. Have you looked at the clearance of your 31's when you turn the wheel? There's less than an inch (with new rubber anyway) so a hard hit and you're taking a fender flare/liner out.

 

The biggest you're going to be able to go are 265/75's without rubbing. But it is going to be close. Its the equivalent of a 32. If you wheel or anything and it tucks up inside the fender it may rub a little. The safest bet is the 31.
