Almost all modern car tires - tubeless (no camera inside) and a radial-ply carcass.
In the radial bus thread in the construction of the frame are parallel to each other, then there is no overlap in a diagonal design.
Tire tread can be: with a directional, non-directional and asymmetric patterns.
Directional tread pattern allows the rapid removal of water from the tire contact patch with the road and reduces the risk of floating over the water wheel (hydroplaning).
To tires with its directional pattern is necessarily present marked with arrows labeled Rotation, which indicates the correct direction of rotation of the wheel. These wheels can not be interchanged on the right side of the machine to the left without removing the bus from disk. If you set the wrong bus, the car in the rain "float" even at low speed.
Non-directional tread design does not require any particular installation, as it is the most versatile. These tires the most affordable, and thanks to its versatility is often installed yet on the assembly line plant.
Asymmetric tires
Asymmetric tires consist of two parts with different patterns, ie the right side - "Rain", the left - "dry". In such tires sidewall inner and outer sides has a different stiffness. Since the outer side has a heavy load (especially in turning), different stiffness allows asymmetric bus better to hold on to the road.
To always have an asymmetrical rubber marking Outside and Inside (or Side Facing Out, and Side Facing Inwards), which points to the inside and outside the bus. After proper installation should be visible only inscription Outside or Side Facing Out. Asymmetrical bus may be both directed and undirected with the tread pattern.
Low Profile Tyres
Do drivers prefer a dynamic driving style is very popular low-profile tires. The ratio of section height to width (series) on a bus does not exceed 55% (195/55, 205 / 50, 225/45, etc.)
Low-profile tires enhance the car's handling at the expense of greater traction. Can reduce stopping distances and improved acceleration. But they have increased noise and stiffness and are more prone to hydroplaning.
In addition, such bus "love" just flat road, as if hit by irregularities substantially increase the risk of damaging the disc. High curbs and off-road tires with better avoided.
Besprokolnye bus
Every year in the world is increasing the number of vehicles that are equipped with the technology of tires Run Flat (Run on Flat). Run Flat technology allows travel on a punctured bus 100-150 km. at speeds up to 80 km / h. In such a tire is used reinforced sidewalls, which does not give her deformed even total loss of pressure.
Most actively promotes new technology concern BMW, which are fitted with this type of tire most of its models, including models under the brand MINI.
Off-road tires
Fans of frequent attacks on the major roads are usually used off-road type tires. Off-road tires have a very high-profile tires and deep, thin tread. This allows the bus better bite in the off-road and climb the slopes.
But such bus ill-equipped to move at high speed along a flat road, as the deep tread poorly kept road and quickly erased. In addition, greatly increases the stopping distance car.
Seasonal bus
One of the main differences between tires is their season.
Seasonal bus divided into: summer, winter and all season. We all do not wear sandals in the winter and summer boots, as our cars do not have to ride in winter on summer tires and vice versa. It must be remembered that in winter, the car booted, even cheap winter tires will go better than the most expensive summer wheels.
Summer tires
The main problem Summer tires to provide maximum grip the tire, and thus the safety. Tires have a high index of speed and good durability.
But when the air temperature below +7 any summer tire begins to freeze (dubet) and loses its grip. This leads to a significant increase braking distances and poor handling. And then come to the aid winter tires.
Winter tires
Composition of winter tires is softer and the tire does not "dubeet" in cold weather. Tread winter tires to the touch will be much softer than the summer. The main difference between winter tires - a large number of sipes - narrow slits in the tread pattern.
Thanks lamellas wheel has good contact with the road, even on snow and ice. But on dry pavement and air temperature above 9 winter tires starts to wear out very quickly. With the advent of spring is not necessary to delay pereobuvaniem on summer tires.
In addition, there are also studded winter tires, are designed for harsh winters. But to use these tires need only truly difficult circumstances.
Spikes are prohibited in many European countries because they are damaging the pavement. Moreover, that modern luxury winter tires copes with snow even without thorns. In Ukraine, the sense to put studded tires are only if you make a trip to the snow-covered regions with untreated roads, such as the Carpathians.
In particularly difficult areas to help snow-covered winter Tyres may find snow chains that need to be with you when traveling on the same Carpathians. Chains are dressed on the wheel only to overcome the low speed (up to 40 km / h) a heavy stretch of road.
All season tires
All season tires is a compromise solution for countries with very mild winter conditions. Roughly speaking, a tire tread half a winter and another summer. They concede in their qualities both summer and winter tires.
