What tires should different trailers use? How to choose the right tire?
Steel wire tire and vacuum tire adapted models
First of all, there are steel tires and vacuum tires, which are subdivided into a variety of trailer axle models, and different models are adapted to different models.
Among them, the most common on the market are 11.00R20 steel wire tires and 12.00R22.5 vacuum tires, which are widely used in flower baskets, standard cars, roll-over dump and various types of hazardous chemical vehicles, of which 12.00R22.5 vacuum tires are equipped with good long-distance road conditions, and the pattern is mostly 3 or 4 lines.
Road conditions are poor, short distance can be equipped with 11.00R20 steel wire tires or 12.00R22.5 block flowers series of vacuum tires can also be, at present to meet the announcement of 12R22.5, 12-layer vacuum tires, but the actual application to 16 layers, 18 vacuum tires, as we all know the tire level is about high, the higher the durability coefficient, so the greater the safety factor.
However, the vehicle management department in order to control overload from the source, in the household mandatory provisions of some models must be installed 12 levels of tires, but some areas of the household when the current external inspection also do not pay much attention to this, if you choose to install other levels of tires to the household, it depends on luck.
12.00R20 steel wire tire has been canceled, which was widely used in large loads of 100 tons, and is now almost not optional when the trailer leaves the factory.
825-16 vacuum tires /820-R20 steel wire tires are generally used in low flat plate, three-wire six-axis, which is also mostly on 13.75 meters flat semi-trailer, the tire diameter is small, the bearing surface is low, and the current level is mostly 16 layers.
385 series of large single tires, designed for lightweight, most matching aluminum alloy rims, recently began to be widely used in the skeleton.
235/75R17.5-16PR and 317/70R22.5 are widely used in standard car transport semi-trailers and mid-axle car transport vehicles, and the level of the announcement is generally 16 layers.
Precautions for using tires
Later purchase of tires should pay attention to the factory time of the tire, trailer axle replace the tire on the same axle should be installed with the same brand, specifications, level, pattern of tires, can not be mixed.
When using, try to avoid long-term overload use, check tire wear and tire pressure in time, otherwise the service life of the tire will be reduced by 20%-50%.
In view of the safety problem of tire driving, driving for a long time, or the road condition is not good, frequent braking, will make the tire heat quickly, need to install the water device to cool the tire water in time, prevent the tire pressure is too high to cause a burst, endangering the safety of driving.
In fact, on this issue, at present, domestic and foreign vehicles have begun to install tire pressure monitoring alarm system, which can send a signal in time according to the pressure sensor installed in the tire, and control the tire pressure through the air charging device, so that it is always maintained at the safe tire pressure.
The tire is a vital part of the semi-trailer, the owners should trailer axle regularly check the tire pattern wear degree, reasonable replacement position, timely replacement of hidden tires, to avoid unnecessary losses.
