When I bought my used Challenger years back it came with an adapter and mini spare, wonder if they have that for the Jeep!

 

spare can only go on back so if you get a front flat your are moving a good rear to front and spare on rear

 

20" rim is the smallest you can go if you want the least amount of work when you get a flat front tire.

 

I bought the same size rim 20 x 10 and 295/R45 non directional tire.

 

Where did you put your spare? Does a 20x10 fit under the car?

 

Back when I had a WK1 SRT8 Jeep, I went to a staggered tire set-up without runflats, and simply signed up for AAA and went without a spare.

 

I've heard of some new cars being sold with no spare - they come with a can of Fix-A Flat (or similar) and a compressor. Might be an option for you to consider.

 

This is how my wife's last 3 cars came (VW CC, Cadillac ATS, and the new Cadillac CTS). Many more will be following suit I'm sure.

 

It does, but I had to modify the white plastic plate cover.
