Racers dont always share when an advantage is on the table.
Overheating the front tires in 60 seconds is pretty common in my Corvette. We compete a lot on concrete which generates more grip. Think ambient to 160* in a minute. I would love to have straights as long as most road courses have to help manage tire temperature. I think the street tires will be the same or easier to make last on road courses.
