In the early 1970s, Frank Nasworthy started to develop a skateboard wheel made of polyurethane, calling his company Cadillac Wheels. Prior to this new material, skateboards wheels were metal or "clay" wheels. The improvement in traction and performance was so immense that from the wheel's release in 1972 the popularity of skateboarding started to rise rapidly again, causing companies to invest more in product development. Nasworthy commissioned artist Jim Evans to do a series of paintings promoting Cadillac Wheels, they were featured as ads and posters in the resurrected Skateboarder magazine, and proved immensely popular in promoting the new style of skateboarding.
Without good grip tape, skaters have a tough time staying on top of their board. The main complaints about poor grip tape tend to be that it was never very grippy or lost its grip really quickly. Once again, we recommend trusting in name brands with years of experience supporting skateboarders. Unfortunately, if you are buying a pre-made complete skateboard, you probably won't have access to the brand name of the grip.
