I only noticed it at work when I arrived-almost flat after driving on country lanes. Totally flat by lunch time. Changed it for my spare -no point calling RAC.
Garage said it was a faulty valve and wacked on a new valve and chucked it back on my car.
Is it safe to use? they didn't examine it, just checked for punctures and blamed the valve.
I drive on 60 miles on country lanes and a bit worried I might have damaged the tyre?
Dam thing is only 4 days old!
I'm counting myself lucky it wasn't on a country lane bend at 60mph!
