Why are tires used as barriers?
The immediate answer has been tire barriers — stacks of tires bolted together into packs that can be installed relatively quickly at areas where the sanctioning body or tracks see a need for cushioning. SAFER barrier inventor Dean Sicking said that was an acceptable stopgap in certain situations.
Why are racetracks often banked at the corners?
NASCAR tracks use banked turns that are sloped to keep race cars tilted inwards. The race cars, which can reach speeds faster than 200 mph, would fling outwards and off the track if not for the banked turns.

Why do they put a sticker on the front of NASCAR cars?

Why do NASCAR tires Mark grooves on tracks?
Because NASCAR tires are designed to wear, they leave plenty of rubber on the track surface. Since most drivers want to stay in the groove, that rubber accumulates and ends up marking the groove.

Why do NASCAR teams use nitrogen instead of air in tires?
By using nitrogen instead of air, the teams have more control over how much the pressure will increase when the tires heat up. On tracks that are more than 1 mile (1.6 km) long, where speeds are faster, NASCAR rules require that tires contain an inner liner.
What happens when a car blows a tire on the track?
If the outer tire blows, the inner tire is still intact, allowing the driver to bring the car to a controlled stop. NASCAR regulates which tire compounds are used on each track.
