Lift/wheel question

[RyCan3]

I have a 4 door 2020 Wrangler Sport. I currently run 33s on the stock Jeep Rims. I’m looking to get a lift installed but have been told I need new rims.

So when I bought my 33s, we tried to put new rims on but it caused the wheels to stick out past the fenders which is illegal in PA (our state sucks, can’t go doorless). I need to find a rim that won’t push my wheels past fender and/or a lift that will work with stock rims and 33s. Any advice?

Suggestion: Fender flare extensions? ?‍

Ok, I am missing something here.

You have 33s on your stock rims and they do not stick past the fenders. Why do you think a lift would change that?

Now, depending on the size of lift you want to install, you will get an axle shift to the drivers side but an adjustable track bar will correct that. Otherwise, your axle width stays the same regardless of the lift you install.

Originally we were looking at the BDS 2 inch lift. Right on their site it says it doesn’t work with stock rims. So then I looked at the Mopar one and it says that it doesn’t work either.

I thought about that, not sure if they will 100% pass inspection in PA. Plus I’m not that big of a fan of them.

It should pass if they cover the tread. Jeep XR package comes with them stock. If they wouldn’t pass, Jeep couldn’t sell the XR package in PA. ?‍

And I live in one of those “anti-tire-poke states” too… feel your pain.

Not sure where you are located in the State but, around me there are very few jeeps (and trucks for that matter) that don't have tires out past the fenders these days. Back in the day when they used to get pissy about it everyone just had a set of junk wheels and tires they'd keep around for inspection day. Not really practical but fun to watch trucks lifted 8" that had 40's on them going down the road with 265/70/15's on inspection day.
I think the thing is to find the right shop to do the inspection. I haven't heard of anyone getting tossed for tires out past the fenders in over a decade but I am sure there are still shops out there that might.
However, if you absolutely want to keep the tires inside the fenders, you just need to get wheels with the proper backspacing and offset to do so. There are tons of threads here on that but off the cuff I am thinking something with 4.5" backspace and -44 offset should keep 12.5's inside the lines.

So, I have the Mopar 2" lift and have the stock Rubicon rims. I don't know the offset difference between the Sport and Rubicon rims but it fits mine no problem.

Please post where it says you cannot use the stock rims with your 33” (285-70?) tires and stock rims.

Ryan,

The lift raises the vehicle and other than a small side-to-side offset (without an adjustable track bar) it does nothing for poke.

Wheels and tire width are the primary factors for poke. The wider the tire and the more negative (-) the offset value (typically specified in millimeters) the greater the backspacing and hence more poke.

Also poke is not necessarily a bad thing (to a point). It provides for more fender-well clearance when turning and provides a wider stance which reduces center of gravity (cg), so therefore improves better overall stability. Granted not much, but certainly in the direction of goodness. Especially when lifting.

The reason for the nanny laws are to reduce the chance to throw projectiles like pebbles past the fender enclosure. These laws however work against an off-roader's best interest due to both reduced clearance and higher center of gravity.

Again to reduce poke, choose a wheel with a more positive offset which brings the centerline of the tire closer to the center of the vehicle and measure the clearance to the inside fender-well at max turn. This of course is easiest to measure with both stock rims and wheels. This gives you the baseline distance that the factory was certified with.

Next, do the math on what you desire. Unfortunately, backspacing and offsets are in mixed units. Backspacing is specified in inches and offset in mm just to make things easier (not). But, stick to the counter-intuitive rule of thumb. Positive offset reduces poke, negative increases it.

Have fun with the planning and living within the constraints of your nanny laws.

For the record, I had chosen the Mopar Lift (net 2.5" of additional clearance) with 35x12.5x17" tires on 17x9 (-12mm offset) wheels. But I don't live in a state with nanny laws (yet). Here are my results:

Completely stock:

With lift on stock wheels:

With lift on 35's:

Resultant poke (with -12mm offset):

Hope this gives you a good reference to aid in your planning.

Happy trails.

I live in Pa. , and I see this all the time (especially on 4WD trucks), the wheels sticking out past the fenders. I have no Idea how they're getting away with it. Are you sure this is still illegal?

I went with a Metalcloak True Dual 2.5" lift and added Synergy rear sway bar links. I'm on stock rims with 295/70R18 tires and sit just inside the fender.

I would send them an email and ask specifically with what you have and/or want to do. They may be referring to 12.5”/315mm wide tires. Plenty of people lift and stick with stock rims.

I always love seeing pics of your Jeep every time you post. Just looks so right proportionally. ?
