Foreign trade PCR tire ISO standard tag

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

30: light diameter ( in )

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.
