33x12.50 tires on 15x8 wheels

I plan on getting some 33x12.50 tires when I get my lift kit, a guy I know told me that I should upgrade to bigger wheels bc the tires will wear down faster with smaller wheels. Then a friend if mine said I should be fine and in ways it's kinda better to have the smaller wheel. I need some opinions because if I don't need to get new wheels that will save me about $600

What wheels are you looking to put the new tires on? If its stock you are going to want wheel spacers so you dont rub on full lock. Or get some 15x8 wheels with a back spacing of 4in or less. I have no idea what the wheel size has to do with tire wear, other than that they are unrelated.

The wheels I was going to put on were pro comp brand, I have 15x8 American racing outlaw 2 wheels but from what I'm hearing ill be sticking with those!

Yeah...there is no reason why they'd run down faster. 33x12.50x15 tires on 15x8 wheels is a very popular combo. I'm running them myself.

Yep for offroading, a 15x8 wheel is a better choice for that size tire. Going to a 10" wide wheel just makes it harder for the tire to stay seated when aired down for offroading. It takes more air pressure to stay seated between two edges that are 10" apart than when they are only 8" apart. I use a 15x8 wheel for my 35x12.50 tires as well. That width wheel works fine on the street too.

I like the look of the 10 inch wheel better but my tire man tells me that the 8 inch is the best choice as far as handling and wear on a 12.5 tire

This is the reason I am thinking about getting rid of my 15x10's for 15x8. Even though I love my powder coated Mickey Thompsons its about function over looks when it comes to offroad. About how low of air pressure do you think is safe to run on a 15x10 with 33" vs a 15x8 with a 33"?

The 15x8 is better off road. The 15x10 is better on the street. A properly inflated 33x12.50 on a 8" rim will wear the center of the tire faster.

A properly inflated tire will wear evenly across the tire. If it's wearing faster in the middle of the tire, then it's over inflated.

Agree with the others...stick with what you've got....You have more choices in tires for 15" rims and they are a lot less expensive than tires for 16" rims.
