You would be fine with the 8" or 10" rim. In my personal opinion, I would go with the 16x8 rim though. Reason being, tires for 16" rims are much easier to get at a lower price than 35's on 15's. I have 35's on 15's and tires are a bitch to buy cause they are expensive. Going with a 16" rim you can get something like a 285/65R16 or a 305/65R16. Just because the tire doesnt say 33x12.5 or 35x12.5 doesnt mean it isnt 35 inches tall. Talk to someone that knows the conversions real well. I used to but have lost my touch. Been out of the business for awhile and cant remember how it goes.

285/65r16

285 / 25.4=11.22 inches wide
11.22 x .65= 7.29
7.29 x 2 + 16=30.58 tall

theres an example of how to convert

We go through this when building race trucks all the time.

Negative. Backspacing is the distance from the inside mounting point to the inside edge of the wheel. The more the backspacing, the further "in" the wheel will be.

To the OP purchasing wheels, obviously a wider wheel will cause more wear and tear on wheel bearing, ball joints, tie rod ends etc., but an actual "number" of how much more is not really predictable.

The main difference between 15" and 16" wheels (aside from the size) is most 15" wheels have much less backspacing (typically around 3.5" or so), while the 16" usually have much more.

And I disagree with the fella above saying 15" tires are more expensive. I can buy 35x12.5 BFG mud terrains WITH a brand new set of Dick Cepek 15x10 wheels for LESS money than buying a set of tires only (same size and tread) for my 17" wheel. And 16" tires are more expensive than a 15" as well. You cant get any cheaper than a 15" tire.

It is way cheaper to buy tires for a 15 inch rim versus a 16 inch rim thats the advantage of downsizing to a 15 inch rim

The smaller the wheel=the cheaper the tire

The larger the wheel=the more expensive the tire

That is exactly what I said. Re-read it.
