As 530 mentioned, the bs on stock wheels is a major problem when you decide to upsize tires..... And the cost of media blasting and powder coating stock wheels hardly seems to be worth it in my opinion. But, it's your $ and your Jeep
Lots of nice wheels to choose from out there... Spend a few weeks looking. If you really want to keep stockers then you'd probably be better off $ wise to just buy some used ones that someone took off. Most folks practically give them away. I'd guess you have Ravines or Canyons on your Sahara.
