Per the "build and price" at jeep.com

Limited has 18" wheels. But the tired are 225/60/r18. Which translates to a tire diameter of 28.6"

Trailhawk has 17" wheels. But the tires are "245/65/r17. Which is a tire diameter of 29.5".

So the trailhawk has .9" larger tire diameter. Unless I'm incorrect on how tire sizes are read.

You are correct. The TrailHawk's tires are 1" larger diameter which is where the 1/2" ground clearance difference comes from. Even though the Limited has larger Wheels.

Re: Limited Suspension Options

That,s the reason I ordered a Limited with off road suspension , active drive 2.
Similar ground clearance to the Hawk.
Kind of like a Trail Hawk dressed up for a formal dance, without the skid plates and tow hooks. It will interesting to see if tow hooks could be added to fit the limited.
Thanks for the lively discussion. We are all winners in the end.

I'm doing the same thing tomorrow, my question is where I can get the wheels and tires that are on the Cherokee that went to Sema, News: SEMA Cherokee preview or at the very least the ones that come on the Trail Hawk.
would anyone know if I could just get the larger tires that are similar to the Trail hawk that fit onto the 18" wheels that come with the limited?

Re: Limited Suspension Options

For the 18" rim a 245/60-18 would be the same approxiate size as the stock trailhawk tires.

Re: Limited Suspension Options

I wonder what affect the larger tires would have on the speedometer, and the newly tuned transmission shifting patterns?

If you change the tire diameter you need to get the computer flashed to the new tire spec.

Who knows if it would actually affect shifting patterns enough to be noticeable.

The back and forth above was lively but the tire size is all that determines the rolling diameter, not the size of the wheel. It is common to see JK Jeeps running "35s" on 16 or 17" wheels, usually the most popular sizes because of cost. But you have to realize that tires with the same size specs still might not roll with the same diameter (air pressure, side wall structure, treads, weight of the vehicle all factor in).

Those of us who will be flat towing our Limiteds behind our motorhomes have to have baseplates installed (which have yet to be designed). We are hoping that they easily fit where the TH tow hooks are connected. Fingers crossed. When we towed a 2007 Tahoe LTZ we had to install baseplates and it was very easy - remove the tow hooks and insert the baseplates, drill one hole and they were in.

TPMS is another consideration. This from the 2014 Jeep Cherokee user's guide:

The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures and warning have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. Aftermarket wheels can cause sensor damage. Do not use tire sealant from a can, or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.

Hey wait a minute. Doesn't Chrysler include a can of tire sealant in those Cherokees that don't include spare tires? That statement is kind of contradictory.

The caviat to that statement is "from a can". Basically it says use what we give you.

I junked the 08 JKs TPMS a long time ago. I went up in size and I am not paying all the extra money to keep them operational. I have checked my own tires since 1975.
