Auto Racing: Valvestems, nascar race, sarasota florida

Question
Dan...I always wondered why the racing tire manufacturers couldn't place the valvestems on the inside of the tire instead of the outside to prevent accidental damage during contact? After all, the tires never need to be inflated or deflated after they're on the car. Thanks...Robert Brown

Answer
Hi Robert.

Sorry but you are under a misconception- - -racing tires have to have air added and removed quite regularly. One of the more common adjustments you'll see in a NASCAR race is a pressure adjustment to improve the car's handling characteristics. Frequently that adjust ment is LESS than a full pound of pressure.   

It is nearly equally so for street cars, certainly every responsible driver should check, or HAVE checked, his tire pressures at monthly intervals.  This will serve to save fuel, eliminate needless tire wear, and make the car much safer to drive.
