Remoulds used to be a byword for poor quality tyres. Reusing a carcass of a worn out tyre, processing it, recladding it with fresh tread to giving it a new life was generally felt to be the lowest rung on the tyre ladder and they were rightly treated with some trepidation by motorists.

At least those that could afford to be choosy.

As a result, in cars at least, the remoulded tyre is all but extinct; killed by a combination of consumer reluctance and the availability of acceptable quality tyres from the Far East.

The same disappearance from the market has not befallen part-worn tyres. In fact, they remain very popular. Figures from industry body TyreSafe suggest that 5.5 million part-worn tyres are sold every year in the UK.

It recently revealed details of a survey in which it purchased a quantity of part-worn tyres from various outlets and the results were not very reassuring. It found 98% of those supplied did not conform with the rules. Many of those were due to incorrect markings, which is illegal, but not dangerous. A very worrying 34% of tyres supplied were what could be deemed dangerous. There were various forms of damage, including damaged sidewalls, insufficient tread depth and in one case, a piece of metal sticking through the tread.
