Angie’s List: Mini Run Flat Tyres
Many new models are now equipped with inflator and sealant kits or run flat tires which are designed to go at slower speeds for 50 miles or more after a tire has been punctured.
Mini Run Flat tyres are an interesting subject.
The problem in my eyes is that cars were getting bigger and faster, and at the same time the car makers were being pressured by governments to make their cars more fuel efficient and greener.
This meant shedding weight and creating engines that were controlled by computers to really hammer down the emissions caused by burning fossil fuels (gasoline or petrol in the
UK). The car companies looked at all sorts of ways to reduce the weight and even the tyre companies looked for ways of making tyres lighter in weight, and indeed they succeed.
BMW come up with the Mini Run Flat Tyres
They also came up with the Mini Run Flat Tyres. This would mean that cars would no longer have a spare, because when the tyre on a car had a sudden drop in pressure (puncture) then the car could drive on, albeit at a slower speed (50 mph) until the tyre was changed. The positives are that the car would not deviate and carry on driving in the normal way and therefor not causing an accident and much safer than a standard radial tyre, also you would not have to get out of the car on a rainy night to change the wheel when you had a puncture.
The drawbacks are the cost of replacing these tyres is much higher than a standard tyre, A new Mini Run Flat Tyres is required after each incident, and on long journeys should you have the need to want a new tyre, then you only have fifty miles to have the Mini Run Flat Tyres fixed. Many tyre companies no longer repair Mini Run Flat Tyres.
In the States the gap between some towns and cities can be hundreds of miles. So you pays your money and takes your choice ?
