Good and picked up by season tires - primarily safety! A feeling of confidence, based on the awareness of safe behavior and / m on the road - this is comfort, which is combined with comfort, which gives all the same good tires. Consequently, the same as / m in the same conditions, is able to deliver a sense of driving pleasure and aversion, because the ride turns into a tedious struggle with his own car. And the thing only in properly selected automotive shoes!
Good tires allow you to move safely and quickly, so - this time saved, which can sometimes cost more than any money. Good tires eventually pay off, because low rolling resistance leads to fuel savings.
Note the number of small accidents where no injuries, only slightly dented fender, broken headlight, etc. Vehicle to avoid collision, did not have just a meter. Bruising and a broken wing lights would not be if the stopping distance was shorter. And the braking distance, among other things, depends on the coefficient of tire adhesion. Therefore, in the same situation, a driver whose tires do not comply with traffic conditions, will fork out for body repair, while the one who took care of the appropriate "shoes", confidently continue the trip. Thus, the tires that are appropriate and / m, and traffic conditions will not only provide safety and comfort, but also help avoid unnecessary costs. Paradoxically, but buying a good tire - it saves.
Choosing tires is very extensive, but the alarming spread of prices for the same type of product. Price of tires for the same a / m can differ several times depending on the manufacturer. Why the difference?
To begin with, what lies behind the notion of "good tire. An experienced motorist call the following criteria good tires:
- has a small stopping distance.
- Car, wrapped in good tires, confidently holds the road.
- Handling is good on any surface.
- Bus is soft, and therefore the car is easier to swallow road surface roughness.
- Bus lightweight (more smoothness by reducing unsprung weight).
- Bus no noise.
- Bus saves fuel.
- Long time to serve.
By way of sealing the interior volume, the tires are tubeless and chamber music.
Chamber tires are composed of tires and tubes with a valve. The size of the camera is always slightly less than the inside tire plane to avoid the formation of folds in the inflated state. The valve is a check valve, allowing air into the tire pump and prevents its way out.
Tubeless tires are distinguished by airtight rubber layer applied on the inner layer of carcass tires (instead of the camera) and have the following features:
- A smaller mass.
- Increased safety when driving, as in the case of a puncture the air comes out only at the puncture (with small punctures rather slowly).
- Easy to repair in case of a puncture.
Wheels for tubeless tires, in addition, must possess a high integrity weld (wheel drive), but also have seating on the shelves of special rim annular projections toroidal (hanpi ") to prevent spontaneous slippage, tire beads (razbortirovku) in critical situations while driving.
Camera and tubeless tires on the location of the cords in the tire carcass can be both diagonal and radial construction.
In the diagonal tire ply cords in the adjacent layers of tissue are (cross) at a certain angle to each other. Number of adjacent layers is usually too early to four.
In radial tires all the ply cords are arranged parallel to the radius from one side to another and do not intersect. This, a small (seemingly) the difference provides the best operational properties of radial tires, practically superseded the diagonal of tire consumption worldwide. In radial tires much less rolling resistance and even more marked increase in tire life.
