How to Find a Tube for a Spare Tire

Cars no longer use tubes. All car tires are tubeless. However, if the spare tire in your trunk wont hold air, it might mean that the wheel itself is defective or has a small leak and air is leaking out through the rim. If this is the case, you can have a tube installed in the tire for limited use. There are tubes of all sizes and they are very forgiving if they are close to the right size.

Instructions

1

Take the spare tire out of the trunk. Inspect the side of the tire.

2

Look for the distinction marked either "P" for passenger tire, or a "T" meaning temporary service. The next numbers are 225/50. These are common to all tires, so dont worry about these numbers.

3

Look after the numbers 225/50 for the number 13, 14, 15 or 16. This is the size of the wheel. It might be any of these.

4

Purchase a tube coordinating it with the letter and the wheel size. Look on the side of the package for the sizes. Some tubes actually are interchangeable, and they will be clearly marked if they are.
