[QUOTE="machoheadgames, post: 441660, member: 18789"] Great looking jeep. On stock wheels, stepping up from 215/75R15 to 235/75R15, 30x9.5R15, or 31x10.5R15 are all solid options. 235 shouldn’t rub at all. 30x9.5 might rub the sway bar, and 31x10.5 might rub sway bar and or spring at full lock. 30x9.5 will not hit the leaf at full lock, that’s for sure as I just put 30x9.5 on my stock TJ wheels which are dimensionally the same as your styled steel wheels (15x7 5.25” BS). Whether or not it hits the sway bar depends on if the suspension sags or if you’re flexing it. I had mind up in the air the other day and at full lock the right tire would hit the sway bar. So maybe it’s when drooped. Regardless, any of the rubbing with stock wheels can easily be fixed with a washer under each of the steering stops. It limits turning just enough to stop the rub. No big deal. If you’re buying tires, I really like the Toyo Open Country ATIII. Check them out for a mild street friendly AT. 30x9.5 fits well and still looks good with lift. For lift options, the only lift I have experience with that I would recommend is Old Man Emu. I had Rough Country 2.5” and BDS 3.5” and I can’t recommend either of those. With practically any suspension lift, be aware that you may or may not need to either drop the transfer case a bit to help the angles on the short driveshaft, or if it’s severe enough change the rear output of the transfer case to a “slip yoke eliminator” setup which also requires an accompanying double cardan driveshaft. The YJ also has inverted T steering which means the drag link is connected from the gear box to the tie rod. The drag link is pretty flat in stock form, any lift starts to put an angle on it which means the tie rod rolls before it gives steering response. The higher lift you go, the worse that is. It may or may not be tolerable for you and you may not care. Drop pitman arms are sold to help with that, and they do, though they are not dropped as far as most lifts raise the vehicle, so it’s still not back to stock. You will probably want to ditch the track bars if you lift, or get relocation brackets at minimum if you want to keep them. Reusing the bars with lift requires binding the axles significantly to get the bar to reach after the lift. As for maintenance, it’s pretty basic. I’d change all the fluids. There are a few minor grease zeros to hit every once in a while, namely the tie rod ends, upper ball joints and front driveshaft slip joint. You might throw in a new set of stock spark plugs and wires if you don’t know when that stuff was done. I lined my floor long ago and I’ve always regretted it.
