Symmetric, asymmetric, directional tyres...how do I choose the right tyre?

Symmetric tyres: Road holding and value for

money

As its name implies, the tread design of a symmetric tyre has identical halves. Less

technical than an asymmetric tyre or a directional tyre, it is

also cheaper. Furthermore, it generally offers another advantage: good road

holding (greater straight-line stability). However, on the downside, it does not

optimise all-round tyre performance, especially for wet road handling.

The symmetric tyre is mainly designed for city or compact cars that only drive short

distances. It is also suitable for motorists looking for good value for money.

Fitting: A symmetric tyre can be fitted any way round. It can therefore be fitted and

rotated without running any risk.

Asymmetric tyres: Safety in all weather

conditions

The asymmetric tread design is characterized by a different inner and outer tread

pattern, with each zone playing a specific role in the tyre’s performance. As such,

theinner part usually has open shoulders to quickly disperse water and limit the risk

of aquaplaning, whereas the outer part is designed to stiffen the tyre for

enhancedhandling and cornering stability. This technical quality comes at a cost:

Asymmetric tyres are more expensive than symmetric tyres.

Several manufacturers have decided to fit their new car models with asymmetric

tyres. This tyre is specifically designed for owners of mid to high end cars looking for

improved safety on wet and dry roads.

Fitting: For asymmetric tyres, the fitting direction must be taken into account. Indeed,

the word “outside” is stamped on the tyre’s outer sidewall.

Directional tyre: For a sporty drive and snowy

roads With its V-shaped tread design and tread blocks that point in the same direction,

thedirectional tyre is easy to recognize. It is particularly efficient on wet roads. Indeed,

in heavy rain, water is quickly drained to significantly reduce the risk of aquaplaning

and give better grip. This tread shape also improves traction,particularly on snow

covered roads and in slush. Finally, car enthusiasts appreciate its sporty look.

The directional tread design is ideal for sports cars regularly driven on wet roads. It is

also recommended for motorists driving on snow covered roads.

Fitting: It is important to follow the direction of rotation shown by an arrow engraved

on the tyre’s sidewall.
