If the MC-tire replacement, better not risk with a comment. If you want to use other associations that are recommended by the manufacturer on his bike, lots of options are available. But make sure that any deviation from the recommended, suitable for your bike is safe and within the law.

CODE FOR MOTORCYCLE TYRES

190/50 ZR 17 (73W) TL

Above is a typical code for pneumatic rear of motorcycle greater capacity. Below is an explanation of each element.

190

Belt width measured in his broader point mm

50

The aspect ratio is the amount (in percent) of the pages of your tyre width. With this example, the sidebar so that 50% of 190 mm = 95 mm height.

Z

Speed score in this exceptional band “Z” is one of the two evaluations. Although “Z” indicates that they are suitable for speeds above 240 km/h (149 mph), it tells us the maximum authorized speed. Displays the speed of a further code gives you this information in parentheses at the end of the code. Both are used in combination.

Reviews for speed:

R = 170 km/h (106 mph)

S = 180 km/h (112 mph)

T = 190 km/h (118 mph)

U = 200 km/h (124 mph)

H = 210 kph (130 mph)

V = 240 km/h (149 mph)

Z = more than 240 km/h (149 mph)

W = 270 km/h (168)

Y = 300 km/h (186 mph)

R

Construcción-R type = radial construction. B = belted construction difference.

Note: If you do not specify built in crosses of the band.

17

Diameter of the RIM, this is the wheel diameter fits the tire, measured in millimeters.

73

Load index to find the real weight represents the number, must be in a band of “index of” table. “With this example 73 = 365 kg (805 lb). Most of the manufacturers of maximum load in kilograms and pounds everywhere in the sides of the deck, so that it eliminates the need for an “index of” table. “This is an important aspect if your bike has strongly taken into account during excursions.

W

Speed is specified in brackets by the number of rate. Tax on the band reaches the maximum speed, the reason why I see the two together. In this example, the band will have a maximum speed of 270 km/h (168) as max 365 kg (805). If there is with max deck can safely operate at higher speeds. In the unlikely in regularly to speed up the evaluation of the speed of your link, please contact the manufacturer for advice or for you, consult the guidelines of the ETRTO (European tyre and Rim Technical Organization).

TL

TL = without a camera.

TT = type of pipe (a pipe).

DIFFERENT INSCHRIFTEN IN BAND

The band broken arrow’s direction must turn in the direction of the arrow, if the motorcycle is in motion.

Manufacturing date of the rule is shown in Figure 4. The first two digits of the week of manufacture is the two digits represent the year of manufacture. Example: 4,972 means that the band took place at the 51st Week 2007 (December 2007). Example: 0611 means that band 2011 (February 2011) took place during the sixth week.

Note: rubber tires are distributed over time, but not in a vehicle. Although it is not difficult and is too old for the quick rule in antiquity, it is generally accepted that year 5 or 6 today should be replaced.

TWI (tire wear indicator) has a majority of motorcycle tire wear, the bar is located in the tread grooves. Wear is about 2 mm above the bottom of the tread groove increases and in several places. If the band wear took the bar, to be replaced. A small triangle or letters “twi” is often used to indicate its position.

M/c-motion.

Max PSI, maximum pressure, to tape in pounds per square inch also swollen.

Max. BAR, is the pressure from the band divided into bars. This is the unit of measurement of pressure in the European countries more outside the United Kingdom. If you click on the revolutions of the engine in Europe, will be good to know, the same PSI (1 bar = 1450 PSI).

Land and tyres sold in Europe must meet European standards with code are marked with an “E”. The number of this letter will show the country that approved the tape for use in road.
