What is an inflatable spare tire?
Expandable/inflatable spare tires are available in some vehicles, including Porsche, Audi, Volkswagen, Mercedes, and Ferrari models. These spares come with a non-inflated tire mounted to the rim and an air compressor. Once you inflate and install the spare, it’s ready to get you to the nearest Les Schwab.

How long does a dummy tire last?
Temporary, ‘donut’ spares are only safe to travel about 50 miles before needing to be replaced. After that, they can become a danger to you and other motorists. Full-sized spare tires can be driven for longer.
