- Grand Sport (2010-2013): Utilized the same wider tire sizes as the Z06.
- Front: P275/35ZR18
- Rear: P325/30ZR19
Run-Flat Technology
Many C6 Corvettes came standard with Goodyear Eagle F1 Supercar EMT (Extended Mobility Technology) run-flat tires. This technology allows the vehicle to be driven for a limited distance (typically up to 50 miles at reduced speeds) after a complete loss of air pressure, eliminating the need for a spare tire. While convenient, some owners opt for non-run-flat tires for improved ride comfort and potentially lower replacement costs, though this necessitates carrying a tire repair kit or relying on roadside assistance.
Performance Characteristics & Considerations
The original equipment (OE) tires were primarily summer performance tires, designed for optimal grip in dry and warm conditions. They are not recommended for use in near-freezing temperatures, snow, or ice.
- Tire Compounds: OE tires often featured soft compounds for maximum adhesion, which can lead to faster wear rates compared to all-season or touring tires.
- Replacement Options: When replacing C6 tires, popular choices include Michelin Pilot Sport series (e.g., Pilot Sport PS2 ZP, Pilot Super Sport, Pilot Sport 4S), Bridgestone Potenza series, and Continental ExtremeContact Sport. Some owners may opt for all-season tires if the car is driven in cooler climates, though this will usually involve a compromise in ultimate dry grip.
- Tire Pressure Monitoring System (TPMS): All C6 models are equipped with TPMS. Ensure sensors are compatible or transferred when replacing tires.
- Aging: Regardless of tread depth, tires degrade over time. It is generally recommended to replace tires that are 6-10 years old, even if they appear to have sufficient tread, due to the hardening of rubber compounds.
Alignment
Proper wheel alignment is critical for C6 Corvettes, especially after installing new tires, to ensure even wear and maintain the car’s handling characteristics. Performance-oriented alignment specifications may differ from standard settings and can be tailored to driving style (street vs. track).
