NASCAR Tyre Gas Quiz

Tyre Filling Gases in NASCAR

• Nitrogen is commonly used to fill tyres in NASCAR due to its beneficial properties.
• Oxygen is NOT typically used for tyre filling in NASCAR; it's less stable and contributes to pressure fluctuations.

Preference for Nitrogen

• Nitrogen is preferred over Oxygen because it minimizes pressure changes during races, keeping tyre performance stable.
• Nitrogen molecules are larger than oxygen, leading to reduced permeation through tyre walls.

Advantages of Nitrogen in NASCAR

• Filling tyres with Nitrogen provides consistent tyre pressure, which enhances handling and grip on the track.
• The use of Nitrogen leads to less frequent tyre pressure adjustments, allowing teams to focus more on race strategy.

Impact of Using Oxygen

• Using Oxygen instead of Nitrogen would likely result in more frequent changes in tyre pressure, causing potential issues with race performance.
