The ZR1 rides on Michelin Pilot Sport 2 (PS2) tires, measuring P285/30ZR19 in front and P335/25ZR20 in the rear. And while the PS2 tire is familiar with enthusiasts, those on the ZR1 were engineered specifically for the car.
We didn’t merely specify a set of off-the-shelf PS2s for the ZR1,” said Juechter. “Michelin’s engineers worked with GM to develop tires for the car that took into account factors such as the ZR1’s performance goals, expected horsepower, curb weight, weight distribution, aerodynamic downforce, top speed and more. The construction of these tires is unique to the ZR1.”
To save weight, there is no spare tire in the ZR1; the PS2 tires feature Michelin’s ZP technology and can be driven for a short distance with zero pressure until servicing can be attained.
