If you’ve ever been unlucky enough to suffer a puncture when driving you know how disruptive this can be. You may have to fiddle with the jack and struggle to get those wheel nuts loose, or have to wait around for some roadside assistance service to help. Maybe you’ve heard of runflat tyres and wonder whether you should consider them. What are they and what do you need to know?
What Is a Runflat Tyre?
The idea of the runflat is to provide temporary relief before you need to change the puncture. In other words, they are designed to enable you to continue driving until you reach a more comfortable location in order to initiate the change. In this way, you may be able to get home or to the nearest garage for assistance. Also, a runflat tyre can reduce the potential dangers associated with a blowout at speed when you’re driving, as they have more structural rigidity.
How Do They Work?
These tyres have reinforced sidewalls, made of toughened rubber inserts. A conventional tyre does not have these special inserts and cannot continue to support the weight of the car once all the air escapes. With a conventional tyre the car’s weight would push down and bring the wheel rim into contact with the road surface. The overall integrity is maintained when you get a puncture in a runflat, however.
Limited Driving Only
This doesn’t mean that you can drive indefinitely on one of these tyres when it is punctured. It’s recommended that you drive only at typical urban speeds for no more than 80 km, but this should be sufficient in order to get you to a place of support.
Replace, Don’t Repair
You should be aware that most retailers will not repair a runflat tyre once it is punctured, as manufacturers advise against this. This is typically because the integrity of the product could have been compromised when it is driven while punctured.
Fitting Them to Your Vehicle
You can consider fitting runflat tyres to a vehicle that was not originally designed to use them as standard equipment. Nevertheless, they must only be installed on vehicles that have a tyre pressure monitoring system as standard equipment. This will ensure that the driver is alerted to the puncture and should start looking for repair assistance. In this way they will only drive within the specified limits, as in some cases they may not even be aware that they have an issue.
Altering the Suspension
It is also advisable to get your auto mechanic to have a look at the vehicle’s suspension when you fit runflat tyres. It may be necessary to make alterations as these tyres have a much stiffer construction. As your car had been designed to run with the original, “conventional” tyres, an adjustment may need to be made to compensate in order to ensure a smoother ride.
