While in the local depot having new tyres fitted I spent the waiting time looking at the discarded tyres in their disposal cage. It was quite illuminating to see just how many had severe damage to their inside faces in the form of a circular scuff mark. In most cases the wear was enough to obliterate any lettering from the inside face of the tyre and in a number of instances the carcass material was showing through. Perhaps some of the officials responsible for speed cushions should be made to visit their local tyre depot and see the dangerous result of their widespread use. No doubt it will only result in more road checks of motor vehicles by the authorities and the motorist being duly held responsible for the state of the inner walls of their front tyres and suitably fined.
