According to statistics, maintenance costs, vehicle tires accounted for the entire 15% of the cost of normal maintenance. Analysis of abnormal wear of the tire causes and take appropriate measures to prevent abnormal tire wear and prolong life, reduce costs and improve efficiency in the use and ensure the safety of their jobs and others have practical significance.
Tires are an important part of the wheel of the vehicle, its technical condition directly affects the traction of wheeled vehicles, by nature, smooth, safety, comfort and economy. According to statistics, maintenance costs, vehicle tires accounted for the entire 15% of the cost of normal maintenance. Analysis of abnormal wear of the tire causes and take appropriate measures to prevent abnormal tire wear and prolong life, reduce costs and improve efficiency in the use and ensure the safety of their jobs and others have practical significance. By analyzing the reasons for abnormal wear of the tire, it puts forward a number of measures to extend the useful life of tires, for user reference you practice in order to save costs, protect the machine, to get better value for money.
Abnormal wear of the tire during use caused due to various factors, it is to make the majority of drivers headache. There are tire pressure is too high, too low, overload operation, poor wheel alignment, as well as rough handling operator driving unskilled caused unreasonable damage as well as an optional external hard objects and installation of tires, will be to reduce the tire life. How to effectively circumvent these abnormal wear, we need to do the following in these areas:
First, strict adherence to standard tire, inflated should check all parts for leaks, and tire pressure should be checked regularly to ensure compliance with standards. To develop the habit of using a barometer measuring the pressure, do not judge with the naked eye. To ensure that the tires have a certain flexibility, at a predetermined load to bear, so that deformation does not exceed the specified range, ensure the vehicle has good stability and comfort while in motion. Spare tire air pressure to charge relatively high, so as not to run gas falling.
Secondly, we must properly matching and installation of tires, according to tire size equipped with the appropriate tube. Tires on the same mechanical assembly shall ensure that the same brand, the same structure and the same performance. If this is not done, it should be on the same shaft assembly of the same brand, same size, the same pattern and the same type of tire; when new tires, should be done with the vehicle or coaxial transducer; with directional tread tires shall be installed in accordance with the provisions of the rolling direction; when switching to new tires, new tires should be mounted on the front wheel, repaired tire is mounted on the rear wheel. To ensure traffic safety, retreaded tires are not allowed to make the steering wheel (front) use.
Third, regularly rotate the tires. After the vehicle for some time, before and after fatigue and tire wear on it is different, and should therefore be required to timely transposition. There are two methods to change a tire cross and round-robin. Transposition law applicable to the regular on the arch of a larger road vehicles, while the law applicable to the regular cycle of change on a relatively flat road vehicles.
Fourth, as well as control tire temperature, vehicles in the process, the tire due to friction, deformation of the heat, so that the temperature inside the tire, the pressure increases. When the tire temperature is high, the buck can not use deflate method, but not to the tires cool splash avoid accelerated tire damage. Should shady place to park at rest, before continuing with the tire until the temperature decreases. The way the vehicle is stopped and the site, to develop safe taxi parking habits. To select a smooth, clean and free of grease ground parking, each tire must be smooth landing, especially vehicle loading overnight, but also should pay attention to selecting the parking place, if necessary, from the top to the rear wheels. When the vehicle is a long time out, you should use the wood to the frame to withstand in order to reduce the load on the tire; not no place to park the tire pressure should be from the top wheel.
Fifth, tires should be stored in the vicinity of the sun to avoid, oils, acids, flammable and corrosive chemicals. All tires should be stored in cooling, dry and dark interior, tires should stand up, non-flat, stacked or hung heart strings. Storage period shall not exceed three years. For separate storage tube should be filled with the right amount of air can not be folded flat or stacked. When not stored separately, they need to be placed within the tire, and the right amount of inflated.
In addition, in the winter cold area, due to the low temperatures, the tire rubber brittleness increased, decreased flexibility, again with a vehicle parked overnight or for a long time after, the start should slowly lift the clutch pedal with a smooth start, the first few kilometers to low speed, be tire temperature rise after normal driving. If the vehicle is suspended on the ice for some time, the ground site may be frozen at the start should be particularly careful to prevent tread tearing. The vehicle is cold outdoor parking area for a long time, in order to prevent the tires and the ground frozen, should be fitted wood or sand in the tires.
