Hoosier Racing Tire was founded in 1957 in Lakeville, Indiana by stock car racer Robert Newton, and Joyce Newton. Newton wished to design a faster tire compound to gain an advantage against fellow racers. This was done by retreading street tires in order to obtain a compound that would adequately gain enough traction.
The most usual cause of damage is drag braking on severe gradients.Because the brake blocks apply directly on the tire, it is heated up, relaxing the interference fit. It is not feasible to fit the tire with such a heavy interference as to eliminate this risk entirely, and the retaining ring will ensure that the tire can only rotate on the wheel center, maintaining its alignment.

The Budd–Michelin rubber-tired rail cars were built by the Budd Company in the United States between 1931 and 1933 using French firm Michelin's "Micheline" rail car design. Michelin built its first rail car in 1929, and by 1932 had built a fleet of nine cars that all featured innovative and distinctive pneumatic tires .
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
A rubber-tyred metro or rubber-tired metro is a form of rapid transit system that uses a mix of road and rail technology. The vehicles have wheels with rubber tires that run on a roll way inside guide bars for traction. Traditional, flanged steel wheels running on rail tracks provide guidance through switches and act as backup if tyres fail ...
Michelines offered unprecedented ride smoothness, but they soon proved to be problematic because the low load that the wheels could bear limited railcar sizes and demanded a high number of tyres (up to 20) per car. Furthermore, they were subject to flat tyres, unlike cars with steel wheels.
Thrall was mainly a freight car fabrication and assembly operation. Additional car types manufactured included boxcars and gondolas.Most cars were designed for standard gauge interchange service on AAR-approved railroads within North America.
