Dealing with Heat

  • Since NASCAR races almost all year, drivers and crews have to deal with a wide range of temperature conditions.
  • When temperatures are warmer, the air in race car tires expands.
  • Crews must adjust the tire pressures so the tires are not over-inflated.
  • Over-inflated tires can cause blow-outs and cost the team time.
  • Slide the handle up and down to see how temperature affects the pressure in racing tires.

100°F

30PSI

A good estimate to use when comparing tire pressure to air temperature is for every 10°F, tire pressure will adjust by 1 PSI (Source:TireBuyer).
