Get To Know About Common Issues Of Tyres
2
Tyres are the most essential part of any motor
vehicle as they are what makes a vehicle move.
Since they get overworked the most on road, it's
but natural that they will be affected by many
physical and characteristic changes with time.
Every motorist comes across some common tyre
problems at some point. Whether it's a puncture,
worn tyres, or misalignment, or any other, it is
a part and parcel of a tyres life on road.  In
this blog we have put together the most common
tyre issues to enable you to spot them before
they become dangerous or significantly decrease
the life of your tyres. It is also important for
your own safety as a motorist. Following are the
most common tyre issues-

Over inflation
Too Much air or nitrogen pressure in tyres
causes the central tread of the tyre to be more
pronounced, leading to over inflation. The outer
edges of the tread on both sides of the tyre will
fail to make contact with the road surface. This
results in the tyre tread being able to disperse
less water in wet conditions. Over inflated Tyres
will wear out and will cause you to have to
replace your tyres prematurely.

Under inflation

• Under inflation is an extremely common tyre
  problem with most passenger cars moving around
  with lower tyre pressures than recommended.
  Drivers and operators do not check them as often
  as they should due to lack of awareness.Correct
  tyre pressure has an impact on many aspects of
  our comfort and safety.  Having too little
  pressure in your tyres can  result in extended
  braking distance, reduced resistance, delayed and
  less precise reactions of the car, risk of over-
  or understeering of the vehicle, more difficult
  parking and a higher risk of punctures .Most
  vehicle manufacturers list the tyre pressures
  required in the driver's handbook for correct
  assistance.

Bulging Tyre

• Bulges in a tyre are usually as a result of
  impact damage. Hitting a pothole, curb, or debris
  on the road can lead to damage of the tyre's
  inner structure. Tyre sidewalls are built to
  withstand some pretty harsh treatment but if the
  inner structure of the tyre becomes damaged it
  can result in a bulge which is an irreversible
  tyre damage and will require the tyre to be
  replaced.

6
Cracking Tyre Rubber

• The rubber on the outside of the tyre is made
  up of lots of polymers that are knitted together
  to form molecules. Tyre cracking is caused by
  these bonds breaking down. Causes for this can be
  - UV Rays/Extreme Heat which leads to expansion,
  aging of tyre that weakens the polymers, water
  penetration, degradation over time, and wrong
  tyre pressure. Cracked or bulging tyres should
  not be repaired and instead the tyre should
  always be replaced.

7
Misalignment

• Another of the most common tyre problems is
  Misalignment.  Its not always easy to detect if
  a cars wheels are misaligned, as this can occur
  gradually over a prolonged period of time.
  However, some of the key signs that the cars
  wheels are misaligned are Uneven tyre wear on
  one side either the fronts or the rears, pulling
  or drifting of the car to one side when driving
  on a straight flat road, or a crooked steering
  wheel which is not straight or level.

8
Puncture

• Punctured tyres usually happen as the result
  of a nail or screw or any other sharp edged thing
  on the road surface, pushing through the tyre and
  penetrating into the sealed air chamber. This
  will result in a loss of air pressure from within
  the inside of the tyre. Most punctures occur in
  the rear tyres as front tyres flick the objects
  up into the air and while bouncing/spinning the
  rear tyres catch them on the point and they
  pierce the tyre. There might be some other causes
  also of punctures.

Flat Spot

• Flat Spots are where a particular section of
  the tyre has been worn flat.  The most common
  reason for this is emergency braking or applying
  the handbrake whilst the car is in motion. This
  can lead to instant tyre wear in specific areas
  due to disruption in rotation, causing excessive
  friction on the part of the tread rubbing against
  the ground. However vehicles fitted with Anti
  locking braking systems (ABS) dont have this
  problem as it ensures the wheels dont lock in
  place.
• Get your rubber tested at Hasestri (Hari
  Shankar Singhania Elastomer and Tyre Research
  Institute), the rubber research institute of
  India that has best in class facilities and
  machinery like Rubber process analyzer, Tire
  aging oven, Humidity chamber, and many more to
  test the quality and performance of rubber and
  its finished products.
