A study by a major city council has found that the majority of part worn tyres being sold at shops in its jurisdiction do not meet minimum standards.
Birmingham's trading standard officers examined a selection of the part worn tyres available in the city's stores and revealed that nine out of 10 do not meet legal standards.
Vehicle owners may have to shell out higher car insurance premiums if they buy below-standard tyres. Some of those assessed during the research had nails embedded, illegal tread depth, exposed cords and inadequate markings, while one was 17 years old.
Only recently TyreSafe revealed that more than one in 10 drivers are more likely to buy part worn tyres compared with a year ago.
TyreSafe chairman Stuart Jackson said: "The results from the Birmingham investigation are extremely worrying. The types of faults found are extremely dangerous and if fitted to a vehicle, could have caused serious accident and injury. This serves as a warning to drivers and we would re-iterate our position that we would always recommend fitting brand new tyres."
Part worn tyres must fit certain conditions to be put on the shelves, among them being permanently marked as part worn, at least 2mm of tread depth around the whole tyre and original grooves clearly visible in their entirety.
