Many people do not think about tires after. Only if they do not pass the MOT inspection, then we buy a new set of tires. Still, you can safely call the tires most underrated part of your car. For example, how do you know which tire on your car should be? And what should be the profile of a good tire?
It is actually a miracle that so few cars skidding. Because the contact surface of a car with the road is surprisingly small. It is often jokingly talked about four coasters. And really a bit. For a not too big car concerns the surface of an A4 piece of paper. That little piece of rubber is sometimes considered to transfer all the forces of the car on the road. So steering, braking and accelerating. It therefore matters a lot what kind of tires you put on your car. Who always wants the best possible driving may have to take a team of tire changers in service. Because a sweltering summer day calls for different tires than one morning with severe frost. And in dry weather you drive the best on a tire which is very dangerous when it rains. But no one makes sense to change tires every day. In practice, all sorts of compromises are therefore closed in the development of a car tire. So you have the best grip in dry weather tires with no tread. But as soon as it rains, a band started in no time sliding over the water on the road surface. The compromise: all tires have profile, so the water can drain. And there are still more compromises. Because a lot of characteristics of tires are inconsistent with each other. Soft rubber gives a lot of grip, but wear faster. A band with a lot of profile does well in the rain, but again makes more noise. And tires that are not too inflated, but nice comfortable ride, but frugal is not the weather. The motorist obviously want a safe tire that you hardly hear, you will always have a grip on the road, where it once more comfortable and economical to drive.
Rubber is flexible, and a road surface is not completely smooth. The rubber and the large holes, for example, very open asphalt concrete as a kind of gear wheels engage in each other. Whether wet or dry, you do not want the footprint of the tire slipping on the road. But when you brake, and acceleration controls, should just slip some of that footprint. The harder you acceleration or passing through a curve, the greater the portion which is slipping. At some point you go over a border, and slides the entire footprint. Then the grip decreases rapidly. Too hard acceleration for example. Then the wheels turn drive faster than the car. Under hard braking are blocking wheels and a longer braking distance the result. And with a little luck you go into a bend in the slip. All you'll need with the tires today still rather do your best for.
The winter really only benefits? Well, you need to purchase the bonds and exchange them twice a year. Because in the summer wearing a winter faster than an all seasons'- or summer tire. The rolling resistance of the winter will be a bit stronger, which leads to higher consumption. But if you swap on time, then you no longer wear. Because in winter you save your summer tires.
You hear sometimes called a manufacturer that his tires efficient driving, but in practice the differences are small. You better watch the tire pressure. It lets you instantly win a lot more. The rule of thumb is to indicate links ten percent harder to pump than the manufacturer of the car. The manufacturer puts the emphasis on comfort. But if you pump up the tires a little harder, then you drive more economically, and the car responds even more alert.
