R external damage R cracks, bulges, punctures R foreign bodies in the tyre tread R uneven tread wear or excessive wear on one side Tyre age Tyres age, even if they are used infrequently or not at all.
Operating and road safety dimin- ish with age. For this reason have tyres replaced which are more than six years old. Tyre damage Tyre damage can be caused by: Wheels and tyres R the operating conditions of the vehicle R kerbs R tyre ageing : Example: tread wear indicator R foreign bodies A specified minimum tread depth is a legal requirement for all tyres. Observe the rele- vant legal requirements for each country. For safety reasons, have the tyres replaced before the legally specified minimum tread depth is reached. A tyre has reached the minimum tread depth when the tread wear indicator (arrow) is flush with the tyre tread.
The less tyre tread depth remaining, the poorer the road grip and handling character- istics of the vehicle, especially if the road sur- face is wet or snow-covered. R insufficient or excessive tyre pressure R weather conditions and environmental fac- tors R contact with oil, grease, fuel, etc. Tyre load-bearing capacity, tyre speed rating and tyre types G WARNING Exceeding the stated tyre load-bearing capa- city and the approved maximum speed could lead to tyre damage or the tyre bursting.
