When is a tyre considered defective?

• A. When it is underinflated
• B. When it is wore to or beyond the breaker strip
• C. When it shows minor cracks
• D. When it has uneven tread wear

Answer: (B)

A tyre is considered defective primarily when it is worn to or beyond the breaker strip. The breaker strip is a critical component of the tyre’s structure, providing stability and strength. Once the tread is worn down to this layer, it indicates that the tyre has reached the end of its usable life and can be at risk of failure. Operating a vehicle with tyres in this condition can significantly compromise safety, as it affects traction, braking ability, and overall handling of the vehicle. While underinflation, minor cracks, and uneven tread wear may signal potential issues and can contribute to a tyre's deterioration, they do not present the immediate and severe risk associated with tyres worn to the breaker strip. Therefore, the presence of such wear indicates that the tyre is no longer safe for use and requires replacement.
