Ask an employee at your local NTB store about obtaining a VIP card. Though NTB might not advertise the program, cards may be available directly from the store. If not, an employee should be able to inform you about any discount programs the franchise offers.

Obtain a VIP card my having a certain number of services -- such as oil changes -- performed at an NTB store, in the event cards are not available for immediate purchase.

Donate items or volunteer time at events sponsored by NTB, and often you will be rewarded with a VIP card. The company has offered VIP membership for participation in canned-food drives and other community-service projects. Such programs likely will be advertised inside the store.

Join a car enthusiasts club, and sometimes an NTB VIP card is included in the welcome packet. Such clubs offer advice and camaraderie to people who enjoy the same particular vehicles.

Register online for NTBs email list -- the "eClub" -- to maximize your chances of hearing about discount programs. NTB offers coupons and information about VIP card opportunities through this list.

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

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.

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.

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.
