Tires are part of the car that also has a big role in supporting the performance of these vehicles. Problems that occur on the tires not only make the car can not be ridden, but also can cause accidents. On the other hand the tire also has a variety of specifications that sometimes confuse consumers in determining the choice. Commonly used as a guide to choose a tire is tailored to the wheels used, brands and prices. Expensive tires may offer many advantages, but if the specifications do not match then the performance of the car was not optimal.
Therefore, familiarize yourself with the tire specification before replacing it with a new one.
Here's the guide:
Needs
Determine the need for tire usage. Car tires used for daily activities of course have different standards with tires used in the competition.
Type and Size
Tires that produce optimum performance against used cars are tires recommended by manufacturers on the basis of various calculations. To find out the type and size of the tire recommended by the vehicle manufacturer, check in the corresponding car manual or on the placard attached to the side area of the door.
Sample tire size 185/65 / R15:
- The number 185 shows the size of the tire width by millimiters.
- Figure 65 shows the aspect ratio size for the tire thickness (%) of the tire's width.
- The number 15 shows the size of the wheels in the inches.
Ban Variations
For example, size P185 / 65 / R15 88H. P on the front is a symbol of (Passenger) this means the tire is intended for passenger cars. For example, LT (Lite Truck) refers to a tire normally used on medium weight trucks, ST (Special Trailer) for trailer cars, T (Temporary) for spare tires. While R means the type of radial tires. Generally there are 2 types of tires on the market, radial type and not radial (biased). At first glance there is nothing different, which distinguishes only on the construction course.
Tire Tread Pattern
the model design or tire tread pattern determines the grip and also the comfort level of the car. A good footprint is a normal design. To provide security in daily car usage.
An aggressive V-type groove has the ability to grab asphalt well. This tire groove is also able to reduce the sound of the tire rotation. Excess tires of this type is the ability to provide better control of wet road conditions and when turning.
Maximum Speed and Load Code
Like the performance of the engine, tire performance also has limitations. Note the letters printed on the tire wall. Even so, this is meant for car-specification racing. But if, you run the car up to maximum speed, make sure the tire can withstand the heat due to the rotation of the tire is spinning fast.
Example: P185 / 65 / R15 88H
Load index is a code of numbers that shows the maximum load that can be supported by a single car tire. The number 88 is the code Load Index, "88" means the tire is able to withstand a maximum load of up to 560 kg (see table below)
These expenses include vehicle, driver, passenger and luggage charges.
If you often drive a car while carrying a heavy load should select a car tire with a larger load index. If not the tires will be more quickly damaged and the worst risk of tires can break!
Speed Rating / Symbol is a letter code that shows the maximum speed limit of tire usage. The "H" code here shows the maximum speed limit that the tire can handle.
In this case it is up to 210 km/h
