a Tyre with a symmetric tread

As the name suggests, the protector consists of two halves symmetrical with the same pattern. Symmetrical tread provides good enough grip on the road and showing moderate effectiveness of water drainage from the contact patch of the wheel and the road surface. These tires, low noise and durable. Due to the lack of directions for installation, allowed for replacement and installation on any wheel of the machine. Tires with symmetrical tread are of average and low price category, designed for city cars and are universal from the point of view of operating conditions.

Asymmetrical bus

The basic difference from the symmetric – difference of tread and outer tires. Dense and hard exterior side of the tread ensure driving stability of the car is cornering, providing it with high maneuverability, and wide drainage channels inner side while driving in the rain successfully complete drainage of water and moisture from the contact patch, reducing the likelihood of aquaplaning almost zero. To ensure proper mounting of the tire outer side of the protector marked "Out Side", inner — "In Side". In the case of improper installation of the tire on the rim the car's handling is significantly reduced and the tire will quickly wear out. Restrictions on changing the location of the wheels with an asymmetrical rubber missing. Tires with asymmetrical tread pattern is an improved version of the classic of symmetrical tyres and are ideal for use in all road conditions. Naturally, the cost is significantly higher than those of tyres with a symmetrical pattern. Designed for cars of medium and premium classes.

Directional tread design

From other tires automotive tires with a directional pattern is distinguished by the configuration of drainage channels, resembling the letter "V". In addition to effective water evacuation from under the wheels, these tires provide good traction in case of snow and off road. Tires with directional tread pattern is a good choice when driving on wet and snowy roads. Among the shortcomings note the high noise of wheels with a pattern "herringbone" compared to classic and asymmetric tyres. During the installation of tires with a directional pattern, it is necessary to observe the direction of rotation of the wheel, checking the arrow marked on its sidewall. Due to the fact that the installation of the right wheel on the left axis, and Vice versa, is not permissible because of the nature of the tread as the spare wheel is preferable to have a tire with a symmetrical pattern. Tyres with directional tread pattern are the most expensive, mostly they are fitted with sports cars and SUVs. Remember that no matter what ultra-high-quality tires you can put on your iron horse, do not relax, allowing yourself to commit serious mistakes while driving in the hope that the expensive and highly functional tires "pull" from any difficult situation. Be careful on the road! You no nail, no wand!
