Motorists are overlooking a crucial tyre safety issue that could pose serious risks, according to tyre experts at Black Circles. While most drivers know the legal tread depth requirement of at least 1.6mm, experts stress that other damage such as cracks, bulges and cuts can go completely unnoticed, especially when not located on the front sidewall.
Beyond Tread Depth
James Harding, tyre expert at BlackCircles, told the Express: "One of the most commonly overlooked issues is the overall condition of the tyre beyond its tread depth. Drivers often focus on how much tread is left, but a tyre can have plenty of tread and still require attention for other reasons. Cuts, cracking, or bulges in the sidewall can be easy to miss, particularly in areas that aren't immediately visible. Uneven wear is another warning sign that drivers might overlook, and it can indicate problems such as incorrect tyre pressure, wheel alignment or suspension issues."
Expert Advice for Drivers
Harding added: "We'd encourage drivers to look beyond tread depth when checking their tyres. Check the pressure, look across the tread for uneven wear and inspect the sidewalls for cracks, cuts or bulges. If there's anything unusual, or they're unsure about the condition of a tyre, it's worth having it checked by a professional."
Manufacturer and RAC Warnings
Michelin has previously warned that deep cuts may have damaged the carcass ply that lies directly under the rubber. This helps to maintain pressure, meaning there is a risk of sudden pressure loss if the part is damaged. A bubble on the side of the tyre indicates the carcass ply has been punctured, putting motorists at risk of rapid pressure loss. Michelin also noted that while drivers may not spot a bulge, they are likely to notice abnormal vibrations while driving.
The RAC previously said: "Yes, cracked tyres are very dangerous and they should be dealt with immediately. If you have noticed cracked tyres, then you should get them replaced as soon as possible. If only one tyre has suffered from a cracked tyre, then it is best to change your tyre and then drive to a local garage. Tyre safety is a vitally important part of owning a vehicle. The rigidity and strength of the rubber polymer need to be maintained in order to keep you and your passengers safe."
