Checking for Physical Damage
A tyre’s overall condition is one of the first indicators of its safety. During a tyre safety check, each tyre is inspected for visible damage, including cracks, bulges, punctures, or sidewall scuffs that could lead to failure. Even minor damage can compromise structural integrity, making early detection crucial.
Assessing Tread Depth and Wear
Tread depth directly affects traction, especially in wet or slippery conditions. The legal minimum tread depth is 1.5mm, but for optimal safety, tyres should be replaced before they reach this limit. Uneven wear can also indicate alignment or pressure issues, which may need further attention.
Tyre Pressure and Fuel Efficiency
Incorrect tyre pressure impacts both safety and running costs. Under-inflated tyres increase rolling resistance, leading to higher fuel consumption and uneven wear. Over-inflated tyres, on the other hand, can cause poor handling and excessive wear in the centre of the tread. A tyre check includes measuring and adjusting pressures to manufacturer-recommended levels.
Checking Tyre Age
Even if tread depth appears sufficient, tyre rubber degrades over time. Exposure to sunlight, heat, and oxygen can cause cracking and stiffness, reducing grip and safety. The manufacturing date on the sidewall is checked to determine whether tyres are still roadworthy or if ageing has compromised their performance.
Ensuring the Right Tyres for the Vehicle
A free tyre check also verifies that all tyres on the vehicle are properly matched in size, tread pattern, and condition. Unevenly worn or mismatched tyres can cause instability and interfere with modern driver-assist features. If replacements are needed, expert advice is provided to ensure the best options are recommended.
