The use of whitewall rubber for wheels has been traced to a small tire company in Chicago called Vogue Tyre and Rubber Co that made them for their horse and chauffeur drawn carriages in 1914. Early automobile tires were made of pure natural rubber with various chemicals mixed into the tread compounds to make them wear better.
Tires take a serious beatingâconstant stretching as they roll along the road, exposure to harsh chemicals (gasoline, oil, acid, etc.), UV rays and heat. That rubber is suffering so that you can travel! Almost all tires will begin to exhibit small cracks in the sidewall after a short period of time. Is it time to worry? The outer layer of rubber on the sidewall is simply a sealing layer to keep the elements away from the inner (structural) part of the tireâin other words, those unsightly cracks are purely cosmetic.
