A directional tread pattern can be identified by arrows on the sidewall that

point in the direction of rotation. Always note the direction of rotation indi-

cated when fitting the wheel. This is important so that these tyres can give

maximum grip and avoid excessive noise, tread wear and aquaplaning.

If, in an emergency, you have to fit the spare wheel so it rotates in the wrong

direction, you must drive extremely carefully. The tyre will not give optimum

performance. This is particularly important when driving on wet roads.

To benefit from the advantages of tyres with this type of tread pattern, the
