Spare tire maintenance
Hopefully you'll never have to use the spare. If you do, it's important that it's in usable condition. Specifically, when was the last time you checked the air pressure?
I checked mine sometime last summer. As part of prep for an upcoming trip, I checked it this weekend. Stamping on the tire says 60 PSI. Tire was at 42 PSI. Not good if I should need to change it while in the middle of nowhere.

60 psi is the storage pressure to account for the air leaks over time. Once you're on the road, anything above 30 psi should do I believe. And since it's a temporary spare, you shouldn't be driving on it for long or doing any sort of speeding in it anyways, it's just to get you to the nearest tire shop.

Sam, I don't think so. The compact spare isn't made the same way a regular tire is. It's a much lighter duty tire.
I'm bringing a plug kit with me and a small 12V air compressor. I much rather drive (in the middle of nowhere) on a plugged tire than the compact spare.

Compact Temporary Spares
Compact temporary spare tires are physically shorter and narrower than the vehicle's standard tires and wheels. Their smaller dimensions require they operate at higher inflation pressures than standard tires (typically 60 psi). Compact temporary spares also feature lighter-weight construction and a shallower tread depth than standard tires to reduce vehicle weight, as well as allow more trunk space to be dedicated to luggage. The compact temporary spare tire and wheel that comes with a vehicle is designed to fit that vehicle only. Never attempt to use a temporary spare and wheel on another vehicle unless it is the exact same make and model.
