There are three things you don’t mess with in NASCAR: engines, fuel and tires.
Tuesday, NASCAR handed down a P5 penalty – the penultimate penalty on the books – to Ryan Newman’s 31 team. Crew Chief Luke Lambert was suspended six races, fined $125,000, and Newman and his owner Richard Childress were each docked 75 points. The tire specialist and team engineer were suspended for six races as well. RCR is appealing the penalty, but I wager they’ve got an uphill battle.
NASCAR’s made its stand loud and clear in the last few weeks. Tire bleeding will not be allowed. If you persist in trying, they’ll come down hard on you.
Running on underinflated tires can be dangerous. Underinflated tires they create more friction and more heat, which leads to not only bad handling, but also can produce structural problems.
Since it’s ramping-up time for the new semester, a bit of recycling is in order. The Science of Speed is a video series the National Science Foundation made to explain some of the science of motorsports. One of the segments (which I wrote) is on Tire Pressures.
