Truck tires specifications

Import and export truck tires specification has many marked approaches, such as 205 / 60R15 89H, P195 / 75R14, P195 / 75SR14, 92S 165R13, 185 70R14, 750 16LT, 31 ×10.50R15LT and so on, so that drivers do not understand, many, did not know that these figures are representative of what parts of the tire, why Mark approach and every kind of.

In fact we see every kind of truck tires specification is not the same country or different arrangement by the use of different marked method. The front tyre has analyzed each part of the name and appellation refers to the plan, these terms are invariant, so, you know different countries marked the approach mentioned in the back tire parts, also widely, what understood.

① ISO symbols. The ISO symbol is the international standard of symbols arranged abbreviation, ISO9000, ISO9001, ISOt9002, as in the previous analysis of Japanese tire, implementation of the specification is ISO9002, Yokohama tire implementation specification is ISO9001.

In accordance with the 10S symbol, the tire specification must be marked in the following ways:

( 1 ) 205 / 60R15 89H

205: tire width ( mm )

60: the flattening ratio

R: radial plan

15: tyre nominal diameter ( in )

89: maximum load

H: maximum speed

( 2 ) 215 / 65R15 94H

215: tire width ( mm )

65: the flattening ratio

R: radial plan

15: tyre nominal diameter ( in )

94: maximum load

H: maximum speed

② P metric. P metric for the United States of America specification.

( 1 ) P195 / 75R14 92S

P : Airbus abbreviations ( PC )

195: tire width ( mm )

75: the flattening ratio

R: radial plan

14: tyre nominal diameter ( in )

92: maximum load

S: maximum speed

( 2 ) P205 / 60HR14

P : Airbus abbreviations

205: tire width ( mm )

60: the flattening ratio

H: maximum speed

R: radial plan

14: tyre nominal diameter ( in )

It can be seen from the above ( case 1 ) tire load capacity and speed level is in together, and in the back, and ( 2 ) cases in the tire speed level and representatives of radial tire plan alphabet R together, while the load is marked other elsewhere, so, ( 1 ) and the ( 2 ) indicate the approach is slightly different. Although this only shows that methods are not the same, but there are many driver brothers in to buy when the tire, often due to meet to tyres and his used car tire marked approaches are not the same, does not dare to use. For example, some vehicle tire code is 185 / 70SR14, so the driver can use the 185 / 70R14 86S tires. This situation the author in the work which are often encountered, thus, together here emphatically put forward, please have this thought or driver can eliminate early fear, relaxation of purchase, purchase the tire as one wishes.
