This innovation eliminates the immediate need for a roadside tyre change and enhances overall safety by preventing sudden tyre failures.
The construction of the tyres marks the primary difference between run-flat and normal tyres. Run-flat tyres incorporate additional rubber and complex compounds in their sidewalls, making them 5% stiffer than standard tyres. This stiffness helps maintain the tyre’s shape and functionality even when air pressure is lost, offering a crucial advantage over conventional tyres.
Types of Run Flat Tyres
There are two primary types of run-flat tyres: self-supporting and support ring. Self-supporting run-flat tyres are the most common type, featuring reinforced sidewalls that keep the tyre from collapsing when punctured. This design allows the tyre to support the vehicle’s weight even without air pressure.
The support ring runs flat tyres; on the other hand, a ring of hard rubber or another material inside the tyre can be used to support the vehicle if the tyre loses air. This type is less common but offers similar benefits in terms of maintaining functionality after a puncture. Both types provide the crucial advantage of allowing you to drive to a safer location for a tyre change.
How Run Flat Tyres Work
The reinforced sidewalls of run-flat tyres are the key to their functionality. When a conventional tyre loses air, it collapses, making the vehicle difficult to control.
