a)
The letters TIN refer to the tyre serial number.
Tyres with directional tread pattern
Tyres with directional tread pattern have been designed to operate best when
rotating in only one direction. An arrow on the tyre sidewall indicates the
direction of rotation on tyres with directional tread. Always observe the direc-
tion of rotation indicated when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplaning, excessive noise and wear.
