2012 with Tow package and Compact spare tire?

Picked up a screw in the rear tire over the weekend, ordered some tires, changed the flat tonight and found that I have the compact spare tire. Checked out wk2jeeps.com and it indicated a full size spare was included with the tow package. Anyone else check out their spare, what was the tire size? Should I have received a larger tire/wheel combo for the spare?

Re: 2012 with Tow package and Compact spare tire?

Me too! The rim is actually a full size rim (8x18) albeit steel so technically they can claim they have provided a full size spare wheel. However, that is far from what most people expect of a full size spare. Misleading advertising perhaps? The tyre is a 245/65R18 XL rather than the road wheel 265/60R18. The problem is that with the road wheel tyres, the cargo bay lid won't properly close. Ironically, if one puts LT 265/60R18 tyres on the steel rim, the lid closes perfectly. That is because LT tyres don't bulge as much as passenger tyres despite generally needing higher pressures. But wait, there's more. If one then does what I did and put an LT tyre on an OEM alloy rim, again the lid won't fully close. This, I think is because despite the steel rim and the alloy rim being nominally the same size, the alloy rim is deeper in its body.

Good thing it was the rear tire, the spare won't fit over the front brembos, thats why they have runflats!

Yep, I guess I was lucky it was the rear tire, would not look forward to the additional tire swapping to move a rear tire to the front.

The spare is on an 18 inch steel wheel but the tire width is only a 175. The jeep definitely looks strange from behind with that thin tire sitting across from stock tire.

My spare is only a 175/60/R18....
Would have been much less surprised if the tire was as wide as a 245 or 265....

OK, sorry, I'm in Australia. I wrongly assumed we all had the same spare.

Re: 2012 with Tow package and Compact spare tire?

You should never put a temp spare on the frount. Not safe.

Agreed, the compact spare on the rear was a bit scary. Can one of you who has a 2012 SRT8 or newer with the tow package look and see what size the spare is. I can't help but think I had the wrong tire included with my vehicle.

Re: 2012 with Tow package and Compact spare tire?

I just looked at my spare. I don't feel like removing it from the bay, but there are no markings for the size on there. All kinds of warnings about temporary use, etc, and inflation maximums. But no size. It's a Goodyear, by the way.

Thanks for responding....I also noticed the tire size on the sticker inside the driver side door with the other tire info. Basically what I can't seem to get the answer to is "what size spare should be included on a 2012 SRT8 with the tow package option?". Maybe I have the right one already....

Re: 2012 with Tow package and Compact spare tire?

As long as the tire is 30.5 in tall thats all you really care about. I measured my spare gy donut tire and it is 30.5 in tall and mine was built in dec 2011. Heres the tire size (Good yr T 175/90D 18) Max speed 50 mph Max air pressure 60 lbs. The wt of the spare tire is 50 lbs.
