Vintage Tire Size Conversion Chart

Use the following chart to figure out the closest modern tire size to your car's original tires. Keep in mind these are close approximations and may not be exact replacements. Before purchasing any tires you should compare outside diameters and the tread footprint to get a better idea on how close a match they are. Your local tire dealer should have this information. Variations in tire diameter will have an effect on speedometer accuracy while the tread foot-print will have an aesthetic affect on the appearance of the car.
