Pro-Trac tires were popular in the ‘70s because they were offered in many sizes to fit modified street machines and hot rods of the era. Let's say you bought a brand new '72 Camaro Z28, you'd head to your local speed shop and order a set of aftermarket wheels and Pro Trac tires to get the radical look with a combination of skinny front runners and wide tires out back. Then came the Pro Street era, when the front tires got skinnier and the rear tires got even wider.
