Anyone know if the inflatable spare would work on the AWD (2021)? I think I read somewhere that it won’t take 17” wheels due to larger brake rotors.
AWD and spare

Correct the awd model uses a minimum 18” rim so the spare is not compatible with it. The larger brake rotors and calipers won’t clear the smaller rim.

I did notice the the Buyers Guide shows a "replace the vacuum with a spare tire" option for the Limited and Pinnacle. That suggests they do have an 18" spare available.
The only spare option I was told when we bought our vehicle was an inflation kit, could be totally wrong in how we were advised. Just sharing the experience, the vacuum is a super handy add on btw!
FYI, On the 2021 Touring L (non-hybrid FWD gas version) that I just received, I have the spare tire kit and 18-inch x 7.5 tires. (When I ordered, the online build configurator says it's a 17-inch spare and deletes the vacuum, and it allowed me to also order 18-inch x 7.5 tires.)
I have not pulled out the actual tire to confirm that it's a 17-inch, but I understand it needs to be inflated for use. (My car also came with the black sealant/inflation pump.)

Brakes on awd are different and also going from 17 to 18 factory tire isn’t a problem
Ah, got it. Yeah, mine is FWD.
I would like to show how I resolved my AWD spare tire issue. I bought a steel 18 x 4 mini spare wheel from a 2012 through 2015 Jeep Grand Cherokee. This wheel clears the rear brakes. Later model Grand Cherokees offered an aluminum rim, that according to CAD does not clear the brakes. Tire store put a t165/90d18 tire on it.

I fabricated a small steel structure, that bolts into the quarter panel, similar to the inflatable spare structure.

I fabricated a bolt to hold the spare tire.

I created a small box that bolted to the floor of the compartment. It holds the jack and tire tools.

I purchased the inflatable spare cover and put a small hole in it.

I fabricated a wood brace that slides into the gap next to the stowed seat. The wood brace stabilizes the spare and prevents the spare from sqeeking against the interior panel.

Tire is clamped in place with through bolt.

I have added a $20 vinyl cover.

1. You Sir, are a most excellent fabricator!
2. This is a well written article.
3. The photos are also good.
4. Thank you!
Thank you for the kind words.
Hello again Kenbenezer,
Is there a part number for the wheel?
Most of the part sites list the part number as 52124856aa but omit the wheel diameter and width. One vendor lists it at 18 X4. Others list a different size? Thanks again. Cheers!
Mopar 52124856AA is the correct PN . It is a 18 x 4.5 steel rim.
Kenbenezer,
Much appreciated.
Do you have part number for the rear quarter panel you bought for your great spare tire setup Thanks
D
Does spare kit work on awds in front brake clearance issue thanks
Mopar interior cover 5RK06PD2AC Bought it on Amazon. https://www.amazon.com/gp/product/B073WGKWMZ/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
Front brakes are larger than rear. My mini spare only fits over the rear brakes.

There are 3 reasons for the spare tire delete. All of these occupy the area the spare tire would normally sit.
1. Storage shelfs ( I have this option in mine)
2. Stow-N-Vac
3. The Plugin Hybrid uses this area for the main 12v. battery
Some people buy the inflatable tire kit and toss it the 2nd row stow-n-go storage area.
Thanks, makes sense now that I know. It seems the comment in the OP about larger calipers and rotors could still be an issue with an inflatable kit however.
