2012 Corvette ZR1 Review, contain about 2012 Review, below include 2012 specs, price and features.  Last year, the Corvette ZR1 was delivered with Michelin Pilot Sport PS2 tires. With a “maximum performance summer” classification (treadwear rating of 220), the well-respected rubber delivered impressive handling. For 2012, Chevrolet is cranking things up several notches by offering the optional High-Performance package (PDE ZR1) featuring new Michelin Pilot Sport Cup Zero Pressure tires. The “track and competition” classified compound (with a treadwear rating of just 80!) is optimized for warm, dry conditions to increase cornering and handling capability. They are “… essentially street-legal versions of a racing tire,” says the automaker. The insanely wide tires (285/30R19 and 335/25R20) come wrapped around all-new staggered-size alloy wheels that are each about five pounds lighter than last year’s 20-spoke wheel.
