SPANISH motoring club RACE has warned of the dangers of using part-worn tyres to save money.
Over 90,000 cars are circulating with damaged tyres and five times more used tyres are now sold on the internet than four years ago, according to the club.
“Tyres can have internal structural damage that is not detected with the naked eye which can cause them to burst during transit,” read a report, which said 236 accidents were caused by faulty tyres in 2011.
