In a conventional two-axle car, without using an emergency spare, which rule must be observed when fitting tyres?

Correct answer

Meet the vehicle’s permitted specifications and fit tyres of the same type on each axle.

Tyres on the same axle must be of the same type, and all must meet the vehicle’s approved specifications or permitted equivalents. Permitted differences between axles may exist, but matching the two left or right tyres is insufficient. Follow manufacturer instructions and do not mix incompatible constructions. Mixing models can affect handling; it does not automatically damage the tread merely because they differ.
