Know this question is all over the forum and everyone says 12.5" is the widest tire you can go on stock rims with a 35" tire without rubbing, so my question is will a 34.6" tall tire that is 12.8" wide rub? With an autospring 2.5" leveling kit.

 

Probably - and it's too wide to run safely on a stock width wheel in any case.

 

What would be the tire width to run on the stock 17" or 18" rims? Would like to get as close to a 35" without having to trim.

I wouldn't go any wider than a 35x12.50 tire on the OEM 17x7.5 or 18x7.5 inch wide wheels. Even a 12.50 inch (305 or 315mm) wide tire is pushing the envelope on a 7.5 inch wide wheel.
