As the world of business development, " ISO " specification will gradually being widely used, at the appointed time, PCR tire specifications world standardization will come. The European symbols refer to Europe and Britain, France, Germany, Italy, Spain, Portugal, Switzerland, Denmark, Belgium, Holland, Ireland, Czech, Poland, Romania and other 14 countries in the domestic and international business between a standard. This standard uses the letter "E " to indicate, that is to say in the European countries of all products ( tire was no exception. So in the following analysis of quality certification is the " ECE " ), and "E" symbol, its products are not allowed to sell.
Tire specification in the European symbols is indicated:
( 1 ) 185 / R14 90S
185: tire width ( mm )
R: Meridian project
14: tyre nominal diameter ( in )
90: maximum load
S: maximum speed
( 2 ) 165 / R13 86S
165: tire width ( mm )
R: Meridian project
13: tyre nominal diameter ( in )
86: maximum load
S: maximum speed
( 3 ) 185 / 70R14
185: tire width ( mm )
70: the flattening ratio
R: Meridian project
14: tyre nominal diameter ( in )
From the cases of 1] and [ 2] cases we can see, the tire code symbol without flattening ratio, actually this kind of tire code symbol in the flattening ratio is 82, but in the European symbols is saved not to write. We now journey has many vehicles such as LADA cars using the tire is 165 / 80R13, but more than 80 series tire was flat in the market as the 82 series of adequate supply, the value is 82 series of slightly more expensive, so, when you know your future European symbols, the original car with false if 165 / 80R13, can be replaced by 165R13, such as the original car is the use of 185 / 80R14 tires, can be switched into 185R14 tires, so you will bring great convenience. Remove the 82 series, usually in the tire width and flattening ratio between all use " - " to indicate, rather than using " / " by mark.
The above three mark method, can also be referred to as " PCR ", namely radial car tire ( in front of the analysis of tire type was the "PC" refers to the analysis of passenger car tire ).
The radial light truck symbol. Referred to as the "LTR " symbol
( 1 ) LT215 75R16
LT: light truck
215: tire width ( mm )
85: the flattening ratio
R: Meridian project
16: tyre nominal diameter ( in )
( 2 ) 30× 9.5 75R15LT

9.5: tire width ( mm )
R: Meridian project
15: tyre nominal diameter ( in )
LT: light truck
( 3 ) 31× 10.5 R15 107N
31: light diameter ( in )
10.5: tire width ( mm )
( 4 ) 750R16 8PR
750: tire width ( mm )
16: tyre nominal diameter ( in )
8PR: hierarchy
( 5 ) 195R 14C 106 / 104N
195: tire width ( mm )
R: radial tire
14: tyre nominal diameter ( 14~14in )
C: commercial use tires ( light truck )
106: load symbol ( a single round of ~950kg )
104: load symbols ( double wheel ~900kg )
N: speed symbol ( N~140km / h )
The digital symbols. Digit symbol may also be referred to as the bias tire symbol.
( 1 ) 4.50 -12 8
4.50: tire width ( in )
-: oblique scheme
12: tyre nominal diameter ( in )
8: layer series
( 2 ) 6.50 -16 10
4.50: tire width ( in )
-: oblique scheme
16: tyre nominal diameter ( in )
10: layer series
( 3 ) LR78 -15 LT
L: load to symbol
R: Meridian project
78: the flattening ratio
15: tyre nominal diameter ( in )
LT: layer series
( 4 ) T115 / 70D15
T: temporary fetal symbol
115: tyre width
70: the flattening ratio
D: diagonal scheme
15: tyre nominal diameter ( in )
More systematic analysis of tire specifications variety of mark method and their meanings. Master these knowledge, will give you in the next purchase tire bring great convenience, you can pass on the tire is not the same as the width of mark method in accounting, then replace or communicate their own car on the use of tire, to achieve their aspirations of purpose.

In 1, I'm driving habits will reduce PCR Tyre life?
Yes! The following are a few helps to extend tire life tips:
Don't overdrive. A high speed will be too much heat, accelerate the tyre wear, weakened the tire durability. Please take the safety, legal speed.
Prevent rapid turning and rolling road shoulder.
Prevent rapid advice and emergency braking.
Don't crush shoulder, avoid pavement potholes and other obstacles. The vehicle travels at high speed, such as tire impact craters and other obstacles will cause the tire to the obstacle and the rim flange occurs between severe kneading deformation, it can constitute a carcass cord tyre cracking, internal compressed air from the gap from the top of the drum kit (see below ). More harsh words, will constitute a tire impact split, instantaneous down completely and can exhibit a vehicle out of control situation.
2, how to maintain the tire?
China certificate for tire would provide more comfortable travel feeling, tread life also extends. Thus:
Please use the correct way to every month ( i.e. in " cold " fetal condition ) check the tyre pressure.
Often view the tire can show off, protrusions, pierce and any damage or irregular wear.
Once found abnormal tread wear, please immediately view the four wheel alignment.
Device for wheel, please ensure the balance.
According to the vehicle user demand may tire manufacturers demand, wheel bearing exchange.
3, what are the factors that decide the life of tire?
Many factors influence the city tire life journey, for example:
Tire drawing
Car condition
Tire protection
Journey conditions
Climate conditions
Driving habits
Thus, it cannot accurate forecast tire journey life. But the master habits about the influence of tire journey life is crucial, so when you control the vehicle during braking, acceleration and cornering please soft operation, which can greatly extend tire life.

This year, the tire market prices frequently collective. Among them, the first price increase occurred in the New Year after the collective inertia "for tire tide" period; second price increase in July; and recently, the market price of the tire came up again in September will be the message, the tire will be The third group experienced price increases. Investment Advisor in the chemical industry researchers often Yi Zhi that tire prices mainly by the significant increase in the cost of tire caused.
Currently, tire upstream raw material prices rising, human costs are also rising, but also by the impact of the RMB exchange reform, the RMB appreciation pressure gradually increased, coupled with the reduced export rebate rate for tires and other factors, tyre companies the cost considerably. The tire pressure brought to offset the high cost would take into account price increases on the tires.
Yi-Chi Chang further pointed out that in tire prices affected many reasons, the upper reaches of the rise in raw material prices is a major factor. According to the Investment Advisor "issued by the tire industry in China 2010-2015 Forecast of Investment Analysis and Report" shows that the major cost components in the tire, the rubber tire about half the total cost. Thus, changes in the price of rubber tires had great influence on the cost.
Since this year, rising raw material prices tires. Which, as one of the main raw material for production of tire rubber, since the fourth quarter of last year, prices soared. At present, the natural rubber price has risen to 25,900 yuan / ton, up 100% year on year increase, which directly promote the rising cost of tire manufacturers. Tire business to offset the cost to bring pressure to raise the price of tires.
