The performance of a NASCAR Sprint Cup Series machine can be altered tremendously by even the slightest of adjustments. As races go on, what worked in one stint may not work in another.

Thus, teams have to constantly keep an eye on things such as tire pressure that can prove critical to ensuring a strong result at the checkered flag.

In the latest edition of “30 Seconds To Know,” presented by Xerox, NASCAR AMERICA analyst and former Sprint Cup driver Kyle Petty explains the importance of tire pressure. It’s certainly much more than a simple matter of keeping the car rolling.
