                                                        Definition of motor tires

             tires are the most important part for a motor vehicle because of the tire is the only part of a motor vehicle that has direct contact with the road. Flashback little, a lot of people probably already know that the tires (made of rubber), which until now used was invented by Dunlop (John Boyd Dunlop) in 1888. Development of the tire to date Dunlop refine the findings.

The parts of the tire

1. Tread / surface of the tire:
Tread / surface of the tire is part of the tire contact with the road surface. The materials used depend on the utility vehicle tire and therefore contributes to resistance, traction and also in conducting maneuvers.
2. Steel Belts:
Maintain the robustness of the tire structure and also maintain the security of objects that can puncture the tire surface.
3. Spiral Layer:
This layer serves to tire more resistant and easier to maneuver.
4. Shoulder:
Shoulder in the thickest part of a tire that serves to protect the tire from shocks or dangerous objects from the outside.
5. Sidewall:
Sidewall is the most flexible in a tire. Factors driving comfort on a tire in a can of this section.
6. Plycord:
Plycord is the main part of a tire that coats the inside of the sidewall and the inside of the tire telatak of air pressure in tires, vehicle loads and shocks from outside.
7. Bead Filler:
Bead Filler filler layer that makes the tire more resistant and easier to maneuver the vehicle.
8. Bead Wires:
Wire coating which serves to hold the tire securely in place on the wheel / rim.
9. Chafer
The part that protects the bead section plycord of heat due to friction with the wheels the bead / rim.

  Types of tires

1. Radial - Plycord layer structure of the Radial Tire Bead to Bead in a perpendicular out. Besides, there is still a coating layer plycord steel belts.
2. Bias - plycord layer for this type are placed diagonally crossed, there is no additional layer in the construction of this bias.

Differences in bias tires and radial tires

     The fundamental difference of Bias and Radial Tyres lies in the composition of the thread that binds to, the following differences in the details :

Differences in bias tires and radial tires
Tires are basically classified into two structures as follows:

a. Bias structure
Ban the bias structure is the most widely used. Made of many pieces of cord that is used as a frame (frame) of the tire. Cord woven zig-zag manner at an angle of 40 to 65 degree angle to the tire circumference.

b. Radial structure
For radial tires, carcass construction cord to form a 90 degree angle to the tire circumference. Thus viewed from the side cord construction is in the radial direction towards the center or crown of the tire. Part of the tires in direct contact with the road surface is reinforced by a kind of belt fastener called "Breaker" or "belt". Tires of this type suffer little deformation in the form of centrifugal force, although at high speed. It also has a radial tire "Rolling Resistance" is small.

Tube and tubeless
Besides the existing structure plycord tire structure is also divided into types that use an inner tube (Tube Type) and the type that does not use an inner tube (tubeless).

1. Tubeless
Tubeless tires have a layer in the (special in it) is stronger than that used in tire tubes
2. Tube Type
This type of tires used tires to be used.

Tubeless tire advantages:

A. It's safer. Figure below shows why more resistant tubeless tires leaking
    when the tire hit a sharp object
2. More efficient and economical, efficient in fuel consumption due to lighter
    (Do not use an inner tube) is more economical because it does not need to buy tires
    in.
3. Cooler, because there is no friction between the tires and tire out in the event
    "Rolling Resistance"

Many questions were asked on the mailing lists are safe tires used tires in tubeless tires or otherwise use the tires in a tubeless tire.

Let's discuss:
For safety reasons it is recommended not be tubeless tire tube and tubeless tire using an inner tube.

1. Tube made tubeless tires:
Differences Tube and tubeless tire construction can be seen in the following figure.
In the picture can be seen that the tire has tubeless tire inner tube liners in this layer does not exist at all. Inner liner makes it more rigid form of the tire so the tire while the tire is still lack of wind form in accordance with the shape and remained attached to the rim.
Is it possible to use a tubeless tire tube?
The answer could be, but for safety reasons is not recommended because if the tire shortage could lead to fatal accidents for motorists.

2. Tubeless tire using an inner tube
For some reason many are using the tires in tubeless tires. Is it safe?
It could use a tubeless tire inner tube, but is not recommended and not safety. For an explanation can be seen in the picture below:
At the time the vehicle is running (F) carry the weight of the vehicle tire and the rider (W). when movement occurs there will be "Rolling Resistance" (N) resulting from changes in the form of tire and road conditions are used. The greater the Rolling Resistance This will result in greater heat.
This has occurred between the outer tire and inner tube are used, but for reasons of tubeless tire inner liner has a more rigid then the friction between tire and inner tube is greater. If excessive heat that occurred in the tires can be dangerous eruption.
