Thank you for that info!! I was unsure of the tire size until now. I think I have to get the compact rim from my Jeep dealer, I haven't been able to find it anywhere else.Older original post but here is the stock rim information needed to find a donut type spare that might fit.
Rim = 6.5 J x 16, ET40, Lugs = 5x110 mm
Offset of 40mm
Center hub bore is 65.1mm
We have the same stock tires on our truck (215/65R 16). Our truck came with a factory Jeep compact spare tire which was a Maxxis brand 165/80 D17 115M size. Although it is thinner than the stock tires it appears to be the same diameter, even though it is on a 17 inch rim. The trucks with a spare tire from the factory had a different molded insert under the platform so this may be desired also.
The rim may be 1 inch smaller but if you size the tire with the right profile ratio, the overall diameter will be the same as the 18's.I went to my local Discount Tire and they put one together for me. I have the OEM 18"s and they put together a 17" alloy and tire for $140, bought a good scissor jack off of Amazon for $22.
It's a full size wheel and tire that fits in the factory hole where the inflation kit used to live. I know the combo is 1" smaller, but I only need it to get me to the tire shop. The goo kit is useless when you have a catastrophic failure and I'm don't want to count on roadside assistance.
I just did that. I ordered the “full size” rim from Dodge (the 17” rim) and I have 18s on my Compass. So, to compensate for the inch of difference in rim size, I went up in side wall height (yes, as we know, the tire size is a ratio of sorts) to match my 18s (pretty darn close). Plus it fits nicely in the spare tire well area. I chose to obviously skip the TPMS on that rim. I anticipate I can get a low profile jack in that general area under the floor coverings as well, if I configure it right.The rim may be 1 inch smaller but if you size the tire with the right profile ratio, the overall diameter will be the same as the 18's.
