The tires on the ZL1 and 1LE are excellent tires. OUTSTANDING tires if you know how to select them. The GYs on these models, like all tires, have a date of manufacture on them. Unlike most other tires, these special blended to GM spec for these specific cars, age starting the day they are made. When they are six months old they have lost roughly 1/4 their grip as the compound continues post cure. This is not from driving or use. It is post cure and would occur if they were sitting in a living room as decorations. In a year the post cure cuts the initial grip by half. A fresh set of just out the the mold 1LE or ZL1 spec GYs have AWESOME grip. I can assure you that the TEAM Camaro engineers were well aware f this when the ZL1 testing was done at the Ring and used fresh tires.
It is far more than just the wheels and tires.
