Check your spare tire before you need it!
Ordered the Overland with "full-size" spare tire. After dealer messed up alignment and tire wore down to threads showing, found out the spare was 17" - other wheels are 18"!
FCA response was, "Overall diameter is the only concern". And the 220/66r17 are the almost the same as the 220/65r18. However; our definition of "spare" and "full-size" differ considerably:
To FCA, the purpose of a spare is to get you to the nearest service station.
To me, the purpose of a spare is to allow me to continue on my way with the least concession to convenience and safety.

To wit: If, on a road trip, the spare is needed, it should replace the flat and allow you to proceed, making the repair at your own discretion and time.
The alternative is to change the spare at 2AM on a Saturday, drive to find the nearest (closed) garage, stay at some fleabag motel until the shops open on Monday - or drive on with clenched teeth, wondering what influence the difference in tire sizes is doing to the drivechain.

Also - FCA does not make 18" steel spare wheels. The only ones available are from China (Wuhan, probably).

The solution proved to be simple and a bit less expensive over a few days - and the dealership in Milton, FL was of no help whatsoever:
A new tire was purchased to replace the one rubbed out by the mis-alignment.
The rest of the work involved three salvage yards:
The unused tire & 17" spare were sold for $50. A used 18" alloy wheel from a 2017 Cherokee was $90. A lightly used matching tire was bought, mounted & balanced for $40.
The total expenditure - new road tire and matching spare - was HALF the cost of the dealer price FOR THE SAME ROAD TIRE ALONE.

I'm sure there are good FCA dealerships who stand behind their work. Unfortunately, the Florida panhandle appears to have the commodity in short supply.
We're on the road with confidence, again, but if you have 18" FCA products with full-size spares, remember: FCA does not make 18" spare wheels.
Ciao!

 

One of the very first things I do with a new vehicle is to check the spare. First to make certain there actually is one, and then to check the air pressure. This isn’t 1975, many current vehicles don’t even offer a spare. If they do it’s usually the tiny doughnut meant for at most a 50-mile driving range. Full-size means it can be run as a long term replacement until the flat is fixed. It pays to pay attention.

So fortunate to have a perfect person like you to give advice after the fact, am l.

 

Sigh, my comment was meant for the unfortunate others who may accidentally read you whiney post, not for you. But there is an upside, I was fortunate to have found another one for the ignore list. Enjoy your KL.

Sorry, Diane - Should have recognized that was from my ex.
