Why are WhiteWall tires white?
Early automobile tires were made of pure natural rubber with various chemicals mixed into the tread compounds to make them wear better. The best of these was zinc oxide, a pure white substance that increased traction and also made the entire tire white. whitewall tires are more expensive due to their specialized manufacturing process, which involves custom molds, specific materials, and labor-intensive assembly. The low production volume and high rejection rates for visual imperfections also contribute to their higher cost.In addition to their timeless look, white wall tires offer practical benefits for e-bike riders. The thicker sidewall construction provides extra protection against punctures and enhances the durability of the tire.Whitewall tire manufacturing requires more steps than standard blackwall tires, and this has always been the case, dating back to the 1920’s. The white rubber is used early in the tire production process, and requires additional work after the tire comes out of the mold.
Why did we stop using white wall tires?
It wasn’t until 1910 that B. F. Goodrich started adding carbon black to its tires, as this ingredient added strength and durability to the rubber. Soon, most new cars rolled out of the factory on black tires, as this updated chemistry resulted in a stronger tire. However, the white rubber did not offer sufficient endurance, so carbon black was added to the rubber to greatly increase tread life. Later, entirely black tires became available, the still extant white sidewalls being covered with a somewhat thin, black colored layer of rubber.
Are white wall tyres illegal?
ARE WHITE WALL TYRES ILLEGAL? Yes, white wall tyres are legal. The legality stems from removing the tyre lettering size on the side wall. Tyres become illegal when they fail to meet specific legal requirements. Common reasons for illegal tyres include insufficient tread depth (below the legal minimum of 1.
