If your current car lacks a spare, auto dealers and aftermarket tire retailers sell spare tires and the related tools for vehicles that originally came with a sealant/inflator kit.

The cost of a spare tire may be less than that of replacing a sealant/inflator kit, and it will help ensure your mobility regardless of the reason for a flat. Spare tires are optional on many cars, and AAA recommends the additional investment when buying a new vehicle. Some sealants have expiration dates and require replacement every four to eight years whether they are used or not. If you used a sealant/inflator kit, you should also replace that, which can cost up to $300 for certain vehicles. If a run-flat tire loses air pressure, or a conventional flat tire is fixed with sealant/inflator kit, immediately take the car to a quality tire repair facility, such as a AAA Approved Auto Repair shop, as soon as possible for a permanent tire repair. Tire sealant/inflator kits can temporarily repair small punctures, but are ineffective for larger leaks or tire sidewall damage.

Run-flat tires can be driven at reduced speeds for limited distances without air pressure. See your owner’s manual for more information. Most cars without them are equipped with either run-flat tires or a tire sealant/inflator kit.

First, determine whether your car has a spare tire.
