I commonly see people looking for answers to questions about C4 Corvettes and the wheel specs? What is the C4 Corvette wheel size? What is the C4 Corvette tire size? What is the C4 Corvette wheel offset? What is the C4 Corvette wheel backspacing? Here are answers to those questions and more below in a sortable file.
Wheel size and offset info
The C4 Corvette wheel sizes, tire sizes and wheel offsets are often confused, but they are very different things. Wheel size is the diameter of the wheel, and wheel offset is the distance from the center of the wheel to the mounting surface on the car. Wheel size refers to the diameter of the wheel. It is usually expressed in inches. So a 19-inch wheel is 19 inches in diameter. Wheel offset refers to the distance from the center of the wheel to the mounting surface on the vehicle. This can also be referred to as backspacing. If you just look at wheel size, it is not possible for you to know what size wheel you need for your car. You also need to know what wheel offset your car uses. The wheel offset is measured from the center of the wheel to the mounting surface on the car. So if you have a wheel with a 20-inch diameter, but an offset of 45 mm, you need a wheel with a 20-inch diameter and 40 mm offset to fit on your car. The reason that it matters is because different cars have different wheel offsets. All offset info for your C4 Corvette is listed in the table below.
Tire size is the diameter and width of your tire. It’s important to know what the C4 Corvette tire sizes are on your vehicle so you can buy tires that are the right size for your year and rims. The first number is the tire’s diameter in inches. The second number is its width in inches. So a 255/50/16 tire has a diameter of 255 mm and a width of 50 mm. In addition to buying tires that are the correct size for your Corvette, also be sure to buy tires that are the correct load rating. The load rating indicates how much weight the tire can carry. For example, a tire with a load rating of LT (light truck) can carry more weight than a tire with a load rating of P (passenger). The sidewall of a tire also has information that you should know, like whether it’s directional or not. Directional tires have tread that faces in one direction, while non-directional tires have tread that faces either direction. If you buy directional tires, be sure to install them on your vehicle in the direction they were made to face.
And for goodness sakes, be sure the factory unidirectional wheels on your Corvette are on the correct side. They are marked on the inside of the wheel.
