Radial tyres were developed in 1946 by Michelin. There was a need for more flexible tyres, which were able to adsorb shocks generated by road surfaces. These tyres are also stronger, which means machines can be operated at higher capacities.
In radial tyres, steel cord plies are placed on the heel of the tyre, and a belt is placed across the carcase. Because cord plies are placed directly on top of each other, the side walls of radial tyres remain very flexible. The image clearly shows the various layers featured in a radial tyre. The bottom layer features steel cord plies and gives the tyre its most important properties.
Advantages of radial tyres:
1. Good steering and better road contact
2. Improved driving comfort thanks to flexible side wall
3. Little heat generated in tyre at high speeds
4. Higher resistance against tread-related damage
Disadvantages of radial tyres:
1. The tyre generates more noise due to its harder tread
2. The soft side walls are susceptible when, for example, vehicles collide with curbstones
3. Minor bumps on road surfaces are dealt with less effectively because radial tyres feature a steel belt
