5.1.Introduction
5.1.1.Basic introduction of tires
5.1.1.1.Optional tires
Tires are the main quick-wear parts of tractors, so we must pay attention to the use and maintenance of tires, so that
the service life could be prolonged as much as possible.
Each tire should have a specified load value, overload can make tires excessively deformed or broken easily due to
lateral overbending; moreover, the tire body fabrics and buffer layers are apt to degumming, which will thus result
in fabric layer looseness and even tire burst especially on rough roads or at the impact of obstacles.
During service, have tires not stained with oil, acid or alkali and other chemical corrosives and avoid exposure in
the scorching sun, lest the rubber go bad due to aging. Often check whether the wheel alignment and toe-in is right,
so as to prevent tire eccentric wear. When the wheel tread is unevenly worn, transpose the left and right tires before
continuous use.
Notice:
The tire replacement is of risks, so such operation must be completed by professionals with professional
equipment in accordance with the operating manual provided by the tire and wheel manufacturers.
Mismatched tires and wheels may cause damages, tire explosion and even injuries or death. Never install
or use any damaged tire or wheel.
5.1.1.2.Steps for correct installation of tires
Tire disassembly
Use special tools during tire disassembly but never use sharp or
tough tools (such as screwdrivers) or hammers to knock at will,
so as not to puncture the tires or damage the tire edges or wheel
rims.
Before removing a tire, first deflate it, press the cover tire edges
on both sides into the groove of the wheel rim, use a crowbar to
force the tire edge on one side near the tire valve out from the
wheel rim, and then use two crowbars to pry out the whole tire
edge in an alternative manner. Remove the inner tube, then pry
out the tire edge on the other side in the same way and finally
remove the cover tire.
