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.
This is the most common type of tire construction. Older tires were made using diagonal bias (D) or bias belted (B) construction. A separate note indicates how many plies make up the sidewall of the tire and the tread. Rim Diameter This number specifies, in inches, the wheel rim diameter the tire is designed for. Uniform Tire Quality Grading Passenger car tires also have a grade on them as part of the uniform tire quality grading (UTQG) system.
