SilverBullet75--- I would highly recommend that you stick with your stock OEM 18x7 wheels, as they have the proper factory "offset" that you will want to maintain, especially in the extremely cramped front wheel wells!!! In addition, the stock wheels are really a nice looking wheel, and you would be hard pressed to find a more attractive wheel than the OEM stock rim. Further; you already own your current OEM wheels, so save your money.

With regard to tires, the largest width you can install on the stock OEM 18x7 wheel is a "285" series width tire. A tire manufacturer that has one of the most diverse tire size selections is: TOYO "Open Country", available in both A/T and M/T tread patterns. Of special note, TOYO makes a LT285/75R18 (35" O.D.) in the "Open Country" that fits the stock OEM 18x7 wheel. Truly amazing tire!!!

Further, there are only three(3) tires manufactured in the world in this specific size LT285/75R18 (35" O.D.), they are: TOYO Open Country A/T; TOYO Open Country M/T; and the MAXXIS "Big Horn" (with TOYO making the only A/T version in the world, as the other two are M/T tires).

Using this specific size tire on the stock OEM 18x7 rims will give you the maximum possible ground clearance, with the minimum amount of trimming (if necessary) in the very cramped area of the front wheel well. I highly encourage you to check out both of the TOYO and MAXXIS websites on the internet before making a final tire decision.
