Wheel and Tyre
the tyre. It is not different from tube-containing tyres in other aspects.
1)
Tubeless tyres have the following advantages:
a)
Tubeless tyres are light in weight;
b)
The pressure of tubeless tyres decrease slowly in case of punctures and thus the tyre bead is not easily
detached from the wheel rim base.
c)
It can be repaired easily;
d)
Such problems as tyre damage arising from non-conformity or frictions between inner tube and cover
tyre can be avoided.
2)
Tubeless tyres have the following disadvantages:
a)
It is difficult for the driver to notice punctures because the tyre leaks air slowly and air pressure
changes slowly.
b)
Severe damages on the tyre tread and tyre sidewall can't be repaired;
c)
If the tyre bead is deformed, air will leak easily. Therefore, it is not applicable for road surfaces of
poor conditions.
The inner tube is smaller than the cover tyre and it will expand by
10% to 20% upon inflation until it clings to the inside of the cover
tyre comfortably. The inner tube shrinks and air leaks into the
cavity between the inner tube and the cover tyre in case of a nail
puncture. Then the air would rapidly leaks out from the valve hole
so that the clearance between inner tube and cover tyre gets bigger
and bigger and the tyre properties change sharply due to lack of air,
thus leading to severe accidents.
Tyre w/inner tube
In case of a nail puncture for a tubeless tyre, the air will leak out
slowly through the small clearance between tyre rubber and nail
so that the tyre pressure will fall slowly. Even if the nail is
removed, air can only leak through the small puncture hole and
therefore sharp pressure drop can be avoided. Meanwhile, the tyre
bead is more closely engaged with the wheel rim in the absence
of an inner tube so that the tyre rim won’t be detached from the
wheel rim within a short period in case of air leakage when the
bus is traveling (the tyre may be detached from the wheel rim if
the steering wheel is turned vehemently when the tyre is at a
low-pressure state). For that reason, air leaks slowly from a
traveling tubeless tyre when it is punctured by a sharp object so
that the driver may have sufficient time to settle the problem.
Tyre pattern and wear mark
There are various types of patterns on the surface of a tyre and these patterns are designed according to the
working conditions of the tyre and the bus and the road conditions. Patters are mainly used to increase the
frictions between tyre and the ground, reduce bus sliding, increase the towing forces of the bus and
guarantee traveling safety on the one hand and help the tyre to discharge water and reduce or preclude
water films on the tyre on the other hand. Reasonable adjustment of pattern layout and size can reduce
noises of the tyre during traveling and make the driver more comfortable. Meanwhile, good pattern design
can enhance the overall profile of the bus and make the bus more fashionable.
