Thank you Metcalf. That might be a little above my level. Well not a little a lot. Lol.37s if you wanted to get fancy. That would require pushing the front axle forward about 1/2" and moving the rear axle back 1/2". They will run the control arms at full lock unless you have offset arms. I would work best with wheels that had 6" backspacing to keep the tire from swinging into the rear of the front wheel opening. Front bumper will likely need trimmed slightly also.
If you want a very practical wheel upgrade, look for a set of PW aluminum wheels (8x17) or Hummer H2 wheels (8.5x17). Both have internal bead locks, and the H2 uses the Dodge bolt pattern, but has a smaller hub hole so you'd need to have the hubs bored out to work. The H2 wheel is a popular upgrade for PWs because because the wheels are cheap on CraigsList and they are very close to Dodge factory offset.
PW internal beadlock wheel. Designed by Alcoa to Dodge specs, were USA-forged from 2005 to about 2008, then made in China by Alcoa after 2008. Rumor is that they switched to another supplier around 2012. Look at that lip on the left side of wheel center. It is bigger than on other wheels and is designed to keep the bead in place when the tire is aired down for offroad use. Other Dodge alloy wheels may look similar on the outside, but there are subtle differences, aside from the beadlock. Seems to work pretty well. The H2 wheel has a similar lip, and there are a couple of aftermarket wheels that supposedly use a similar design.

The internal lip on the PW wheels is noticeably larger than the lip on most other wheels. I don't air down a lot, but some of the PW guys have reported good results down to about 12-15psi with these wheels on bigass trucks. The external beadlock rings are not DOT approved, with very few exceptions. But there are so many fake beadlock wheels on the road that I doubt anyone other than a tire shop would notice.The outer bead uses a mechanical clamp style retaining ring.

I did not say "legal," I said "approved." Big difference. OP seems to want to stay dead stock or very close to it. Therefor, the PW or H2 wheel is a smart move while he is buying tires, if he can find a set for low $. I bought two sets of H2 wheels, one set mint for $300 and the other lightly used for $200. That's for all four wheels, not for each. Hard to come up with a smarter upgrade on a budget.DOT 'illegal' beadlocks are not the issue that most people think they are. There are no states that make beadlocks illegal per say.....they just don't say they ARE legal. They may not be manufactured under SAE wheel guidelines, but they are not 'illegal'. Basically the wheel manufacturer is releasing liability if anything goes wrong. Shops don't like to work on them for the same reason.....just like they don't like to work on older 2pc wheels split-rims or dayton style wheels.
