Complete Buying Guide to Run Flat Tyres

Many drivers have found themselves in situations where they are stranded on the side of the road with a flat tyre. This rarely ever occurs at a convenient time and requires immediate attention. With run flat tyres, drivers can continue travelling and attend to a flat tyre at a time that better suits their schedule. By learning about the types and considering the benefits and characteristics of run flat tyres, car owners can determine if they are worth the investment for their vehicle.

 

Types of run flat tyres

Before making a purchase, shoppers should understand what run flat tyres are and how they work. Like the name suggests, these tyres do not deflate and are able to resist the effects of deflation if they are punctured. The three types of run flat tyres are self-supporting, self-sealing, and auxiliary-supported. Understanding the characteristics of each type of tyre can help shoppers determine which ones best meet their driving needs.

Self-supporting tyres

Self-supporting run flat tyres are the most common type. These tyres feature reinforced sidewall construction that supports the weight of the vehicle when air pressure is low, or even when the tyre loses all of its air. Additionally, they are made from stiffer and tougher rubber than standard car tyres. For light trucks and passenger cars, drivers can travel up to 80 km at speeds around 80 km/h; however, this can vary depending on the manufacturer.

Self-sealing tyres

Self-sealing tyres contain a layer of sealant inside the tyre that helps to prevent the loss of air in the event of a puncture. If the driver runs over a nail or other sharp object, he or she can remove it and still maintain pressure. Unlike other run flat tyres, self-sealing tyres do not withstand significant damage or large gashes, as they only seal holes that are 5 mm or smaller. Self-sealing tyres resemble traditional tyres, and do not add significant weight to the vehicle. Two major manufacturers of self-sealing tyres are Continental and Pirelli.

Auxiliary-supported tyres

Auxiliary-supported tyres feature a support ring attached to the rim that supports the weight of the vehicle in the event of a flat tyre. These systems work with standard tyres, so purchasing replacement tyres is no more expensive than usual. Additionally, auxiliary-supported tyres do not affect ride quality. Unlike self-supporting tyres, there are no speed limitations or distance restrictions on auxiliary-supported tyres, which is why this type of run flat tyre is commonly used on armoured trucks and military vehicles.

 

Considerations

In addition to choosing a type of run flat tyre, shoppers should take several factors into consideration before installing a run flat tyre on their vehicle. When making a purchasing decision, it is important to evaluate the characteristics of the tyres to determine if they are worth the investment. Some factors to consider include safety, stability, construction, and lifespan.

Safety

One of the biggest advantages of using run flat tyres is that people can drive on a flat tyre and do not have to make a sudden stop on the side of the road. This means that drivers do not have to change a tyre in a potentially dangerous situation, and can instead drive their cars to a safe and comfortable place before replacing the tyre.

Stability and handling

Run flat tyres are generally more stable than standard tyres in the event of a blow out, and sudden deflation of the tyre has little effect on steering and handling. In fact, run flat tyres often require a tyre pressure monitoring system (TPMS) to alert the driver that the tyre has lost pressure. Without it, drivers may not immediately notice that they have a flat tyre.

Construction and lifespan

Run flat tyres use thicker and sturdier materials than standard auto tyres so that they maintain their integrity even when punctured. However, like standard tyres, run flats are not invincible and do require regular replacement and maintenance. Drivers are encouraged to replace the tyres every 100,000 km.
