Tires are the only component to connect vehicles and road. The safety of tires on running condition depends on contact area on the ground. Therefore, it is very important to hold regular running. At the meantime, tires must be replaced correctly.
Fitting Removing or Mounting Tires
Always follow the recommended fitting and unfitting procedures for pneumatic tires.
Only specially trained and authorized personnel should carry out tire fitting and unfitting.
Always ensure that the tire is well positioned and seated on the rim before inflation pressures and safety guidelines.
■ Anunderinflated tire will deflect too much leading to excessive sidewall flexing. Underinflation typically results in irregular or uneven tread wear, sidewall radial cracks, ply separation, loose or broker cords inside the tire, fabric carcass fatigue and belt edge separation.
■ Never exceed the inflation pressure for the wheel. It may be lower than the inflation pressure for the tire. When actual wheel loads aren’t known, tires should be inflated to the pressure recommended for the size and ply rating.
■ It is natural that inflation pressure of tires will increase when shift. Therefore, tires can’t be reduced pressure.
■ When tires is cold, inflation pressure must be checked at least once per two weeks.
Load and speed
■ Load ability of earthmover tires depends on mounting machine type. The same spec tires can have several defferent speed ratings, which must be at least equal to the highest value of unload speed.
■ Fo empty catty when machine shift.
■ Avoid continuous running in order to prevent tires’ too hot that will make tires damage.
■ The tire mounted in the vehicle must be checked frequently. Clean all the part of the tire and check if any parts of the tire, such as tread, shoulder and bead, are cracked, broken and damaged or not specially. Any tire existed in the damages above-mentioned must be inspected by the expert.
■ If the tire runs in the tough road with stone and pothole, or running for a long distance, even though it looks ok, it should be checked by the expert to avoid the hidden damages that will shorten the lift of tire.
■ Once the tire is punctured, stop the vehicle and replace it with good one, otherwise its construction will be damaged After the tire punctured is demounted, it should be checked further. Liquid sealant is not recommended because it can hide the damage and holdback the further inspedtion.
■ If the tire can be repaired, this work must be done by the expert.
■ It is necessary to listen to the advice of manufacturer and the expert concerned when the tire is replaced. Used and uncertain tire is never recommended.
■ The new tire should be mounted with new tube if the tire needs tube. The new tube must match with new valve and new O ring.
■ Tire should match the rim strictly when it is fitted in the rim, Otherwise the tire can be damaged.
■ It is natural that tire ages even though it is not used. When tire ages, cracks happens in the tread and sidewall, even deformation of carcass. Olf tire and aged tire must be inspected by the expert to confirm if it is still used.
■ Tire in the vehicle left unused ages and cracks easier than the one used frequently. If the vehicle stays for less than average 7 days, tire should be rised by the jack or lift devices to reduce load, and avoid exposure to the sunshine.
■ Tire whether the rim is fitted or not must be stored indoors in a cool, dark, dry, draft free area, avoid exposure to direct sunlight, heat, ozone, gasoline and oil and away from electrical devices. Tires fitted rim should reduce the pressure when stored.
Dual Pair Tire Mounted
Tire mounted in certain axle must be of the same size, the same type (industry code), the same construction (both radial or both bias) and the same tread wear. The assemblies operated as a dual pair must have same outside diameter.
