Spare tires have evolved over the years from 2 to 1 to a donut and now to an air compressor. The photo above is what your state of the art spare tire looks like. Let's give it a test;

I wanted to see if this ContiMobilityKit could be used as a simple method of checking tire pressure and making changes as required. I am very happy with the results. No need for the "goo" bottle unless you have a flat. The compressor once plugged into your auxiliary jack will reach all four tires with ease. I found the air pressure meter gave me the same PSI reading as a digital gauge. Over the years I have found that using those air pumps at gas stations and even dealers puts water into your tires. When your tires get hot, your PSI will really increase due to water vapor. Using this on board compressor will not put any water into your tires plus if you have it, you might as well use it...It's kind of funny as tires on cars got larger and larger, your spares got smaller and smaller and now none at all.

For some reason, I can't see the picture, either with Chrome or Explorer browsers. My car came with the spare tire option, but it sucked up all the room on the trunk so I took it out. I ordered the compressor kit from the dealer's parts department and put that in the sub-trunk compartment. Good tips on its use for maintenance as I haven't even opened it yet to look it over.

No problem with the pictures here with IE10 (which is otherwise a piece of crap. ;) ) I've assumed that if you have to use the kit to fix a puncture, the tire then needs to be replaced rather than repaired. I would think having the whole bottle of goop hardened inside the tire would at least make it out of balance.

I think the reason they stopped the spare option was due to the fact if you had to replace one of your tires it could not be transported. To big for the trunk and too heavy for your lap...You might want to post on this site what the dealer is getting for the compressor kit. Pascha

I thought that too. If I get a flat, am I just going to leave the tire and a very expensive rim by the road-side? That's why I just pulled it out. If I get a flat and can't fix it, I'll just call AAA to flat-bed it away. I didn't order the tire, it was already in the car I bought off the showroom floor, otherwise I would have skipped that option.

compressor Kit price was ~$180 USD.

I am surprised that Jaguar did not use run flat tires on these cars since there is no spare tire or practical way to use one. I am not saying that I am a fan of run flats, just thought Jaguar would use them.

I also have a 2012 Corvette GS that came with run flats and the ride is not as smooth as it could be and the road noise from the tire gets louder as they get more miles on them. I was considering going to a non-run flat tire when the original tires wear out and buying a compressor kit something like the one in the F-Type.

The only flat that the compressor kit wouldn't fix is one from a blow out or running over something that would cut the tire. In those relatively rare cases, you resort to calling AAA from your cell phone.

For some reason i thought the car came with run-flat tires but now i can't find that info anywhere. Does anybody else recall?
