Just ask @cosine he knows!
In regards to #2, the stock rim is 7.5. I don't want to purchase new rims, but are you saying that in order to fit 35in (or the 315/70/17) tires, I need a wider rim? If I did get different rims, that would throw this whole thing off correct?

In regards to #3,
If you do go taller & wider w/ your tires and you do use the stock wheels you may need spacers to keep from inner contact when the suspension is under full flex, and the steering is at full lock. Downside is the narrowest spacers typically used are 1.25" thick so you will have some tire poking outside the fenders.

Yep your right I had it backwards. If you want to run a 35x11-5/12.5 you’ll need at least and 8-8.5 rim unless you find a tire shop willing to mount on the stock rim. The 315 is able to be mounted on the stock rim as it only calls for a 7.5 wide rim.

If put on too narrow of a rim you tend to get crowning and not even tread wear.

Most good tire shops will not mount a 35*12.5 on a 7.5" rim. They will mount 315/70's on a 7.5
315(metric) is a 12.5”(imperial) tire.
They are the same thing, one is metric, the other is imperial.

You can absolutely mount 12.5 tires onto a 7.5 rim, many on this forum have done so.

Many 35x12.5r17 tires are also written as 315/70r17

True, the only caveat is if you happen to have a tire warranty issue, if the manufacturer states the approved wheel width is wider than 7.5" they could deny a claim. There are some shops that won't mount them on wheels outside of approved wheel widths too.

This is what I was referring to. Most national chain shops won’t mount the 12.5 on a the stock rim. The 315 they will because most tire manufacturers only call for the 7.5 with the 315.
