NASCAR Racing: Tires, goodyear eagle, eagle tire

Question
What is the average lap life of a NASCAR Goodyear Eagle tire.


Answer
Hi Mr. Mulvey,

It varies on different tracks.  At darlington, a 1.5 mile track, they lasted about 58-62 laps.  Granted, they wore out by then, but they still worked at 185 mph.  So i am not all that great at math.
Also, if the asphalt was recently repaved, the tires last longer and have more grip.

Hope i helped!
