Considering the tyre is arguably the most important safety component on a vehicle it's alarming that a large percentage of motorists have no idea what the symbols on a tyre sidewall denote. In an attempt to help address this problem, TyreSafe has just produced a leaflet entitled Car Tyres and Your Safety, available to download from www.tyresafe.org, which contains an illustration and a simple explanation of what all the symbols, letters and numbers on a tyre's sidewall actually mean.
