I haven't had the budget to do a lot of upgrades to my new 17 JKUS yet.. but I'm slowly building it up. I decided to go try the lower level trails to see how it does as it is now. 33" tires AT/MT hybrid Falken Wildpeaks, 2.5" TF lift. I scraped my skid plates once or twice, my tires hit my fenders twice. But it did pretty good. I have gone through much more challenging terrain just running around the neighborhood and going to Galveston. I think I expected more variety from the park.
