For better traction, the Corvette has larger standard tires than the RC F (F:245/35R19 & R:305/30R20 vs. F:235/35R19 & R:275/35R19). The Corvette Z06/E-Ray/ZR1’s tires are larger than the largest tires available on the RC F (F:275/30R20 & R:345/25R21 vs. F:255/35R19 & R:275/35R19).
The Corvette’s standard 305/30R20 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the RC F’s standard 35 series tires. The Corvette Z06/E-Ray/ZR1’s 275/30R20 front and 345/25R21 rear tires have a lower 30 series front and 25 series rear profile than the RC F’s 35 series tires.
For better ride, handling and brake cooling the Corvette has standard 20-inch rear wheels. Only 19-inch wheels are available on the RC F. The Corvette Z06/E-Ray/ZR1 has standard 20-inch front and 21-inch rear wheels.
The Corvette has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The RC F doesn’t offer vehicle monitored tire inflation.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the Corvette can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The RC F doesn’t offer run-flat tires.
