Corvette C3 Tires
From 1968 to 1972, Corvettes were outfitted with F70-15 bias-ply nylon cord tires. The shift to radial tires occurred in 1973 when the first Corvette was fitted with them, and this radial tire trend continued for all models from 1973 to 1977, utilizing GR70-15 radials.
The diameter of the F50-15 tires aligns with that of the contemporary P215/70-R15 tires. Likewise, the dimensions of the GR70-15 size bear a strong resemblance to the commonly employed P225/70R15 size seen in modern times.
From 1978 to 1982, P225/70R15 tires were the standard equipment for all Corvettes, while the choice to opt for P255/60R15 tires at an extra cost was also available.
Tire sizes
The standard presentation of tire size usually takes the form of "225/60R15," conveniently located on your tire's sidewall. Now, let's delve into its components:
Width (225): The first number denotes the width of the tire in millimeters from sidewall to sidewall when properly inflated.
Aspect Ratio (60): This number represents the tire's aspect ratio, which is the ratio of the tire's height to its width. In our example, the height is 60% of the tire's width. A lower aspect ratio often means sportier handling but can result in a stiffer ride.
Construction (R): The "R" signifies that the tire has a radial construction, which is the most common type today. Radial tires have layers of fabric that run perpendicular to the direction of travel, offering a smoother and more stable ride.
Rim Diameter (15): The final number indicates the diameter of the rim in inches that the tire is designed to fit. Using the correct rim size is essential for proper tire seating and performance.
