GAC gs3 - How Is Tire Bulge Generated

Q&A
How is tire bulge generated?
Causes:
Since the tire shoulder or the tire bead close to the tire shoulder heavily
hits against the outside foreign objects (e.g. pot hole, road shoulder and
stone) during driving, severe extrusion between the rim ange and the object
causes broken yarn of the tire fabric, and then the inner air of the tire rises
from the broken yarn and forms bulges.
Countermeasures:
If a tire is bulged, its safety will greatly decrease and the tire is easily to
burst. It is recommended to replace the bulged tire. If you insist on using it
(suppose the bulge is not severe), install it to the rear wheel.
Preventive measures:
Either too high or too low pressure does no good to the tires. If the pressure
is too high, the tire will become hard, reducing the riding comfort of the
vehicle, and the tire will be stretched too long like a rubber band, have no
elasticity, and be easily broken when subject to great external force; if the
pressure is too low, the tire will become soft, the fuel consumption of the
vehicle will rise, and the tire will tend to break due to great shear stress
generated between an obstacle and the rim in case of collision.
Moreover, it is also important to improve the driving habits. During driving
at high speed on a road section with bad road conditions, the tires are likely
to run into a pit or other foreign objects, leading to severe compressional
deformation of the tires between the impacting object and the rim flange,
which causes broken yarn of the tire fabric at the sidewall. In this case, the
inner air of the tire rises from the broken yarn and forms bulges. Besides,
during climbing the road shoulder or parking, tire scraping against an
obstacle may also damage the sidewall, forming bulges. Accordingly, try to
avoid these situations.
