2018 XLT rim and tire size
 

I want black rims on my stock 3.5T, what size rim should i look for? average size, nothing big.. I like more rubber with the All Terrains. And what size tires would I be looking for?

I would say stock rim is average size. If you aren't going to lift it, probably nothing bigger than 20'' wheels. I would just replace what you have. Tire and wheel size are stamped on the tire. Just look there. You already have 18'' if not 20'' on it already. I really liked my BF Goodrich AT.

I have the cheap XL rims 17" I think 7.5. Tires are 265/17. Can I get 20" rims using those tires no lifts. It's the one thing I did not like about the truck was the rims. If not 20" would 18" be ok. Thanks.

No, you can't use 18" or 20" wheels on tires meant for 17" wheels if that's what you are asking. But you can get 18" or 20" wheels with tires that are the same diameter. For example if you have 265/70/17s now, then you go with 265/65/18s or 265/55/20s

ok, thanks. What about 17' rims 7.5 width to 8"? Some rims I like are only available in 17x8, not 17x7.5

Unless you go crazy with the backspacing, 17x8" wheels will be fine
