The owner of a 56-plate BMW 5-series has written to the Sunday Times motoring pages about his run-flat tyres deflating 12 times in 3 months. Surprisingly, the dealership can’t find anything wrong with the tyres.
At etyres we find it inconceivable that the problem couldn’t be diagnosed. Of course over a long period of time air seeps out of tyres, but not at this rate.
If you’re reading this BMW owner, give etyres a ring and we’ll see if we can solve the mystery.
For those wondering what all the fuss over run-flat tyres is about, here’s a quick run-down – they are becoming increasingly commonplace on the roads of the UK as more car manufacturers fit these advanced tyres as standard equipment or as an optional extra. However, there are still some misconceptions surrounding the fitment and use of this new type of tyre.
Run-flat tyres, or self supporting run-flat tyres to give them their correct title, should not be fitted to a vehicle not designed to accept them or without a pressure monitoring system. Equally they should not be mixed with conventional tyres as the handling and performance characteristics of the two types of tyres are quite different. Mixing of different brands of SST tyres may also not be advisable and the motorist should check with the manufacturer of the tyre or vehicle for advice. It is recommended that the same make and type of SST tyre be fitted across the same axle.
