Zorluk: ZorTyre Safety and Requirements

Under UK road traffic regulations, a passenger car tyre is legally compliant for use on public roads as long as its tread depth measures at least 1.6 mm across the central three-quarters of the tyre's breadth, even if an external sidewall cut exposes the internal cords or ply structure.

Cevap: Cevap

Cevap

False. A tyre is illegal and unroadworthy if its internal plies or cords are exposed, regardless of whether the tread depth satisfies the 1.6 mm minimum requirement.
Under UK road safety and vehicle construction regulations, a tyre is illegal if it has any cut deep enough to reach or expose the internal ply or cord, or if it exhibits any lumps, bulges, or tears, regardless of whether the tread depth meets the 1.6 mm minimum standard.

Adım Adım Çözüm

1
Identify the statutory criteria governing tyre roadworthiness under UK law.
UK law enforces dual requirements: minimum tread depth thresholds and structural carcass integrity.
Tyre safety requires both adequate water dispersal capability from tread grooves and pressure containment strength from an undamaged casing.
2
Evaluate the condition described in the scenario against legal structural defect limits.
Although 1.6 mm meets the minimum tread depth for passenger cars, exposed cords or plies represent a severe structural failure.
Cuts deep enough to reach or expose ply or cord cords drastically elevate the risk of sudden tyre blowout.
3
Determine overall legal roadworthiness.
The presence of exposed cords renders the tyre illegal for road use, making the statement false.
A single structural defect invalidates compliance regardless of satisfactory tread depth.
