Tires & Pressure | [NASCAR] Science of Speed

NASCAR tires don't have "air pressure" because they're filled with nitrogen. The culprit responsible for increasing tire pressure during a race is friction. Using dry nitrogen gas helps the team predict how hot the tire will get and how much the pressure will "build" during a race.

nice presentation.
she nailed it at the end.I like her style

The reason you swerve or turn left to right aggressively is to clean your tires off. Under caution your tire will cool and pick up debris. To have a good restart you need as much of your tire in contact with the track.

What a great video, I'd like to sit down and talk to these folks, thanks for posting the video.

I found this very interesting, I have a converted ambulance campervan (European style only 4 wheels, no doubles on the rear) It weighs 2980kg. I run my Continental Fourseasons2 tyres at near max pressure, 69PSI. Am I running the risk of being to "hard" and risking punctures? They are all season tyres so have soft blocks to the touch.

You need a safety margin, run it at 65 PSI

What gauges are they using to check the tire pressures?

[@bayestraat]

Fahrenheit? Whats that

more practical version of Celsius

I thought it was about real racing... not nascar...
