The tire is one of the parts in the motor of our most important, thetype of tires is a lot of kind in the manner intended, sometimes even impressed at the main function aside just for looking appearance. Wrong select tire code caused fatal to the wearer, like wrong modification is useless money, time and savety, it is important to determine tire code before using it. 

In the selection of tires that need to be considered are as follows, 

1.  Load index is the tire's ability to carrying the load.
2.  Appropriation tire. for example, whether to be used for sport, touring or just replace the standard tires only. different designation will be different variants of tire wear, despite having the same size. The difference lies in the load index and speed index (symbol rate).
3. Converting sizes. This is important if will change with different sizes.Consider the code in motorcycle tires (a combination of letters and numbers)

Size Tire
Front Tire		Rear Tire
Metric	Alphanumeric	Metric	Alphanumeric
80/90	MH90	110/90	MN90
90/90	MJ90	120/80	MP85
100/90	MM90	120/90	MP85
110/90	MN90	130/90	MT90
120/90	MR90	140/90	MU90
130/90	MT90	150/80	MV85
		150/90	MV85

Numbers listed as 120/90 17, which is known as code metrics and used as a standard in the automotive world.

Number 120 states the width of the tire in millimeters, measured in a straight line from one side of the tire to the other side of the tire.  

The 70 states aspect-ratio between width and height. The higher the number, the tire will be higher

Number 17, the diameter of the rim which is expressed in units of inches.

MT70 serial number, 17, represents the same tire size, but dieekspresikan in alphabetical code. M means the tire is used for motorcycle, T means the code is wide, and 90 is the aspect ratio, and 17 is the rim diameter

Speed ​​and construction tires

Apart from the above code, 120/70VR 16, two additional letters represent the class speed and tire construction. Each letter in class stated speed maximum speed that can be covered by a ban on the recommended load capacity

 .

Rating	Speed miles per hour	Speed kilometers per hour
Q	99 mph	160 km/h
S	112 mph	180 km/h
T	118 mph	190 km/h
U	124 mph	200 km/h
H	130 mph	210 km/h
V	149 mph	240 km/h
W	168 mph	270 km/h
Y	186 mph	300 km/h
Z	Over 149 mph	Over 240 km/h

The next letter stating the method of construction used tires

Text R means radial construction

Text B means belted bias.

TT or TL letters stating type of tires

Text TT means Tube Type TT (tire inner tube)

Text TL mean TL Tube less (tires without inner tubes)

The difference between Tire Tube (regular) with tubeless tires

Tubeless tires, Tubeless tires are tires that do not need a tube on the inside (butyl rubber inner tube) so it is more secure than regular tires. has impermeable halobutyl that when combined with wheels will form the air seal. If the tire is leaking air only flows through the leak that was quickly deflated tire.

While regular tires the tires can explode when punctured like a balloon that resulted in a flat tire quickly, which can lead to loss of control of the vehicle. Regular tires have drawbacks such as:

- That is not right fitment 

- The friction between the tire and the tire that causes heat and eventually explode

all that is the lintle info, thank's for visit don't forget to savety riding....
