Quote: “Watkins Glen is always a challenge with high loads, high heat and an unforgiving track,” said Ken Payne, technical director, motorsport, Michelin North America.

“The other thing is there’s significant elevation change and significant high speed, high load corners. If you look at, say Watkins Glen versus Road America, Road America has more straightaway length. 

“Tires naturally reject a lot of heat. You don’t have as much straightaway distance at The Glen versus Road America to reject that heat. So, you get more of an accumulation of energy that is going to and remaining in the tires.”
