Please help with tire fitment.......

I have the stock 20" FX4 rims, and a 2" leveling kit installed. Can I use a 14" wide tire. 355/50 R20 (34 x 14 x 20).

If not how about a 325/60 R20 (35.3 x 12.8 x 20)

I DO like the look of the tires outside of the wheel well.

Also I found some rims that I like, they have a +35 offset, does that mean they will be out or in the wheel well further.

What is the offset and backspacing of the stock FX4 20s?

Thanks in advance, and sorry for more tire and wheel questions.

I doubt you will be able to fit the 14" wide tire in the wheel well or on the rim. You could fit the 325 but it will be close. The +35mm wheel will stick in the well possibly so much that your tires will rub on the upper control arms. The stockers have 5.5" bs.

If you want the sticking out look you need to go with a 33" or less and a low/negative offset wheel. If you want tall tires you need to keep them in the wells with a higher offset. Maybe 18-25mm.

Or buy a 6" lift and go wide and tall.

Oops. I was thinking of the 18s.
