Tire and quietness of the car
Tire and quietness of the car
Suspension hardly affects much of the smoothness of the vehicle, but the tire design with tire thickness and tire tension is the most powerful impact on the feeling.
There have been many articles dealing with tires and tire problems. The market also has many different tires, but all car tires have the same characteristics as moving on an air cushion. Analyze the design of a tire to see that although the amount of fish as well as the number of layers of cloth lying inside the spout has some certain effects, but the thickness of the tire is the decisive factor affecting the smoothness car's door.
Traditional radial tires often have very soft tires. Two factors that affect the hardness of the tire are the number of layers and the height of the tires. Signs on the tire can tell us how many tires a tire has. However, the 4-layer parent tire does not mean that its structure actually consists of four parent layers. This figure only shows that the tires have the same durability as the four-layered structure. Most of today's cars use tires ranging from two to four grades, while SUVs or large trucks use tires with six or more parentboards. The more layers, the harder the tire, and consequently the lower the comfort level. However, the advantage of multi-layered tires is that it can handle large loads.
The ratio of the tire's width and width is the second factor affecting smoothness. Tall tires, usually 70% (shown in 70 in symbol P215 / 70R-15) can significantly neutralize the vibration when the car goes into bad road. Low tires (only 45% as sports tires) are less likely to break the shocks, but they increase the feel of the steering wheel as the tire treads move faster on the tires. Modern suspension systems nowadays provide significant improvement in ride comfort, while racing tires still feel more shock-resistant in the cabin.
Proper pressure is another important factor in increasing the tire's life, providing a smooth ride and safety. Slightly inflated tires often cause the tire to bend continuously. Although it feels like the car is running smoothly, but this continuous movement makes the tire warm and high temperatures can cause the tire to malfunction. Look in the tire manual or tire label to see what pressure level is right for you.
Tire inflatable tires are only suitable for certain situations. If you have a habit of driving fast, or carrying heavy loads, increase the tire pressure. Folding or racing tires require tighter tires to keep the tire rigid and prevent the wheels from ringing. However, never let the tire pressure exceed the maximum allowable pressure on the tire.
Most cars now have maximum tire pressure in the range of 32 - 35 psi (one pound per square inch, equivalent to 2.2 kg / cm2 - 2.4 kg / cm2). Large tires have a maximum tire pressure of 45, 60, or even 75 psi (3.1, 4.2 and 5.2 kg / cm2). To keep the car stable and safe, it is advisable to check the tire pressure every month.
Get to know the symbols on the tire
All information is printed on the tires. For example, with tire type P205 / 55R16, the letter P indicates that this is a car tire, and LT means that the light truck tires can withstand heavy loads. dulcet. Next number 205 indicates the width of the tire; The 55th lateral slant indicates that the tire's height is 55% of the width of the tire. The letter R represents the radial and the last letter refers to the diameter of the tire in inches.
In addition to size parameters, you can also see a group of numbers and letters like 89 H. The numbers indicate the tire's load capacity and the letter represents the maximum safety velocity of the tire. When active. For example the H means that tires can operate safely up to speeds of up to 210 km / h; T to 190 km / h; And S to 180 km / h.
