What does the 91W 91V 94H 94T on the back of the Pirelli tyre model mean?

1. The number in front is the tire load index, and the letter in the back is the maximum speed under the specified load.

for 615 kg and 94 for 670 kg. W is 270 km, V is 240 km, h is 210 km, and T is 190 km.

3. W and V both represent the ultimate speed of the tire, that is, the speed of the tire is very different, and the speed is the critical speed of a tire, that is, if the driving speed of the tire exceeds this speed, it will be easy to cause the danger of puncture.

Proper use and maintenance of tires:

Maintain normal internal pressure. Air is the food of tires, and the car can be said to drive on the air, therefore, the proper internal pressure is the life of the car. If the air is too high, it's like high blood pressure.

He who; Lack of air is like malnutrition.

Both will shorten the service life.

2.Change the mounting position of the tires regularly. The aim is to ensure that each tyre is evenly worn, thus extending its service life.

3.If the tires are overloaded according to the specified load capacity, the same damage will occur as if the air pressure was insufficient. When loading, the carrying capacity of each tire should also be kept basically the same.

4.No rusted, deformed, or welded steel rings are used.

5.Avoid sudden acceleration and braking.

and sharp turns. 6.Do not mix tires of different specifications and qualities on the same axis.

7.Use with tires and rims.

matching valves, and ensure that the valve caps are often covered to prevent sediment from entering.

91w91 - refers to the load index 91, which means that the maximum load of this tire is 615 kg, and the four tires are 615 4 = 2460 kg.

w — refers to a speed level of 270 km/h.

91v91 represents the tire load index, which is the maximum weight that the tire can bear. 91 means that the maximum weight that the tire can carry is 615 kg.

V stands for the speed class of the tire, which is the maximum speed that the tire can withstand. V is the maximum speed that the tires can withstand is 240km h.

94h94 represents a maximum load of 670kg.

"h" stands for speed class coefficient, which indicates a maximum speed of 210 km/h.

The 91 in the 91V and 91W after the tire specification model identification represents the load-bearing index of the tire, indicating that the maximum load of this tire is 615kg. The difference between the tires 91V and 91W is the letters V and W at the back, the letters represent the speed class of the tire, V means that the maximum speed that the tire can carry is 240km h, and W means that the maximum speed that the tire can carry is 270km h.

Michelin potato finch tiresThe superscript 94W and 91W represent the load factor and speed coefficient of the car, respectively. The number 94 represents that the tire can carry 670 kg, and 91 represents the actual load value of the tire is 530 kg.

Main advantages: Tires are classified by application, including truck tires, bus tires and mining tires. In addition to the size of the tire wall, the truck must also indicate the age of the layer.

Tire 91W and 94W are the specifications of the tire, 91 refers to the load factor of the tire, indicating that the load bearing weight of the tire is 615 kg, 94 represents the tire load index, indicating that the maximum weight that the tire can bear is 670 kg, W refers to the ultimate speed of the tire, indicating that the ultimate speed of the tire is 270km per hour. Tires are a kind of grounding and rolling annular elastic rubber products assembled on various vehicles or machinery, usually installed on metal rims, which can support the body, cushion external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle.

The 94W and 97W marked on Michelin tires represent the load factor and speed coefficient of the car, respectively.

The meaning is as follows:For the load index of the tire, the maximum load of each tire corresponding to 87 is 545kg, and the maximum load of each tire corresponding to 91 is 615kg.

V W represents the speed class of the tire, and the beam speed class indicates the maximum speed of the tire carrying the specified load under specified conditions, the maximum speed of V is 240 km/h, and the maximum speed of W is 270 km/h.

q 160 km h.

r 170 km h.

s 180 km h.

t 190 km h.

h 210 km h.

v 240 km h.

w 270 km h.

y 300 km h.

Zr speed above 240 km/h - If the rubber coarse mark has zr, e.g. P275 40ZR17 93W, then the maximum speed class ("93w""w") for 270 kmh.

For the load impact weight index of the tire, the maximum load of each tire corresponding to 87 is 545kg, and the maximum load of each tire corresponding to 91 is 615kg.

V W represents the speed class of the Repent tire, and the speed grade indicates the maximum speed of the tire under the specified conditions, the maximum speed of V is 240 km/h, and the maximum speed of W is 270 km/h.

Tires 94V are better than 91V. Because the speed level V of 94V and 91V is the same, they both represent the maximum speed of the tire is 240km h, and the difference between them is that the load index is different, 94 represents the maximum load capacity of the tire is 670kg, and 91 represents the maximum load capacity of the tire is 615kg, that is, the load capacity of 94 is greater than 91, and the performance of natural impact resistance and other aspects is better than that of 91v.

Precautions for tire replacement.

The inflatable outer diameter and cross-sectional width of tires with different specifications are different, and the load distribution is different when installed on the same axle of sliding burning, so it is required that the same specifications must be on the same axle. In addition, the front and rear axles do not have special requirements for the vehicle and its tire specifications.

It should also be the same. The tire pattern is different, not only the wear is different, but also the adhesion gear is different from the ground. The inconsistency of the left and right hand-lift tire patterns of the car (such as the longitudinal and transverse patterns installed on the same axle) will affect the smoothness of the car, and unilateral and tail flicking will occur during emergency braking.

Therefore, the coaxial tire pattern and groove depth should be the same.

94V is good, 91V maximum speed is 240, 94V maximum speed is 270, load capacity 91V is 615kg, 94V is 670kg, coaxial two tires must use a model.

Influential. The difference between tire 91V and 94V is that the maximum load capacity of tires is different, the maximum load capacity of 91V tires is 615kg, and the maximum load capacity of 94V tires is 670kg, of which the "91" of tire 91V refers to the tire load index of 615kg.

Key points in choosing tires:

Priority should be given to original tires first, which are the best match for the speed of the car and the maximum load of the car, so theoretically, it should be prioritized when changing tires.

1) "Vehicle", Zhonghong refers to motor vehicles and non-motor vehicles sold in the book of difference.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power to drive on the road in the Spring Festival.
