Runflat tyres

RunFlat tyres revolutionize how drivers navigate Ireland's roads, providing an innovative solution to the common issue of tyre punctures. You'll find a wide range of these advanced tyres available at Eiretyres.com.

When Run Flat International came into being, their purpose was mainly to create military equipment that will be productive even in extreme condition. When things go south, and you run a flat tyre in the middle of the battleground, you can’t really afford to stop and change the tyre – you need to keep going. This is why Run Flat International designed a system that could be controlled safely until the driver and its passengers arrive at a safe place. They provide tyres of all sizes and types, going from military and emergency vehicles to VIP cars, buses, and trucks. The company has more than 20 years of experience in the field. So, Run Flat tyres are something you may want to invest in if you dislike stopping in the middle of the road to change your tyres.

The Innovation of RunFlat Tyres

RunFlat technology empowers tyres to continue operating for about 80-100 kilometres following a puncture, at speeds of up to 80 km/h. These "zero pressure tyres" or "self-supporting tyres" typically achieve this resilience through reinforced sidewalls. Some RunFlat tyres, however, use a support ring or an added sealing layer inside the tyre to prevent deflation or dislocation from the rim upon a puncture.

Distinguishing RunFlat Tyres from Conventional Tyres

Unlike standard tyres that deflate quickly when punctured, making them unsafe and inoperable, RunFlat tyres maintain their structure due to their reinforced design. This robust construction allows them to carry the vehicle's weight and makes them safe to drive on, despite a puncture. They feature a heat-resistant rubber compound, increased sidewall width, carcass reinforcements, and a special tread structure, and are roughly 20% heavier than conventional tyres.

Different Types of RunFlat Systems

RunFlat technology is realized through three primary methods:

• Carcass/Sidewall Reinforcement: This popular type uses a reinforced carcass, sidewall, and heat-resistant sidewall ring to prevent a punctured tyre from sagging and maintain good traction.
• Support Ring: Here, an elastic support ring is affixed to the rim of standard-designed tyres. When the tyre loses pressure, the vehicle rests on this ring, allowing the car to drive for an additional few dozen kilometres.
• Self-healing Construction: These tyres have an additional layer of sealant material that closes minor cuts or punctures, maintaining the tyre's volume and shape.

Manufacturer RunFlat Tyre Labelling

Car manufacturers use different labels for RunFlat tyres. For instance, BMW, Rolls-Royce, and Mini cars use the RSC (RunFlat System Component) label, while Mercedes-Benz uses MOE (MOExtended), and some Audi models use AOE (Audi Original Extended). Bridgestone uses RFT (RunFlat Tyres), Michelin uses ZP (Zero Pressure), Continental uses SSR (Self Supporting Runflat), and Goodyear and Dunlop use ROF (Run On Flat). Nokian uses FlatRun, while other manufacturers may use the abbreviations ZPS or SSS.

Using and Maintaining RunFlat Tyres

RunFlat tyres can be tricky because a puncture might not be immediately noticeable as the tyre visually appears undamaged. It is highly recommended to use RunFlat tyres only with a pressure sensor and ESP electronic aid for maintaining directional stability.

Although RunFlat tyres can be mounted on standard rims, they require a specialist service station equipped with Easymont pneumatic installation for fitting or removing. The tyre's outer tread can be restored if not deformed.

Despite their significant advantages, such as eliminating the need for a spare wheel or a tyre repair kit, and not affecting the car's handling when pressure reduces, RunFlat tyres are 1.5-2 times more expensive and heavier than standard tyres. Their repair and replacement also require specialist service stations.

RunFlat tyres from Eiretyres.com can help you enjoy a more convenient and secure driving experience. However, if you're planning a long journey through unfamiliar terrain, carrying a spare tyre is still a prudent measure, considering the limited number of technical services within an 80-kilometre radius from a potential puncture location.
