UNSAFE TYRES

Unsafe Tread Depth

Ensure that tyres have more than 1.6mm of tread.

Most new tyres have about 8mm of tread pattern when manufactured but as tyres wear their ability to disperse water reduces. Tyres should be replaced before the tread wears down to the level of the Tread Wear Indicators.

The Tread Wear Indicators are moulded into all major grooves of tyres in at least four positions around the tyre. These indicators sit at least 1.6mm above the bottom of the grooves.

If you are unsure of how to correctly read your tread depth, visit your nearest Bridgestone Select and they will be happy to assist.

Aged Tyres

A number of vehicle manufacturers are now advising against the use of tyres that are more than six years old due to the effects of ageing. 
 

Unfortunately there is no hard and fast rule to determining the age at which a tyre should be removed from service. You can check the age of your tyres by looking at the Tyre Identification Number (pictured). The last four digits indicate the week and year the tyre was manufactured e.g. this tyre was manufactured in the 48th week of 2004. 

Motorists in doubt are advised to check with a tyre professional at their nearest Bridgestone Select.  The tyre professional is able to conduct a thorough visual inspection of the tyre as well as investigating its history and will be able to advise on the need to replace the tyre.
