Track Temperature Meaning in NASCAR

Track temperature measures the actual heat level of the asphalt racing surface. This heat significantly impacts how much grip the tires provide during laps. Sun exposure increases the surface temperature and makes the track very slick. Cold tracks usually offer much more traction for the heavy racing cars. One team might find the car handles poorly as the sun sets. This change requires crews to adjust tire pressures to compensate for heat. Higher temperatures cause tires to wear out much faster than on cool days. Engineers monitor these levels constantly to predict how the car will behave. Understanding this variable helps teams maintain a fast pace throughout the afternoon.
