I have 10 track days so far this season with my stock 2019 ZLE and am only getting 3-4 track days (typical DE event with 4 25 minute sessions) out of the front OE Goodyear tires. I have the car set at the GM recommended track alignment and keep it that way for street driving, but use a second set of OE wheels with the Michelin Pilot 4S tires for the street. I aim for 34-35 psi hot in the front and rear for track duty. The rear tires do much better and are getting even wear. I am an instructor with my DE club and drive the car pretty hard on the track. I would love to find a fix without sacrificing cornering performance.
