The rolling resistance of a
tyre determines its fuel consumption behaviour. Tyres with low
rolling resistance consume less fuel and vice versa. The rolling
resistance of a tyre depends on various factors such as the material
used in its construction, tread pattern and even size.
While these characteristics
are not in the hands of a motorist to manipulate, there are several
other determinants of rolling resistance which a driver has full
control over. If you are attentive to those, you may save hundreds of
Pounds every year on your fuel bill.
Tyre Pressure
Fuel efficiency and
under-inflated tyres are not something you’ll hear in the same
sentence often. Let’s understand why.
When a tyre is under inflated,
its contact patch increases. It results in an amplified friction and
heat build-up. The engine has to expend more energy as the rolling
resistance of these tyres increases with friction.
It is estimated that every 1
PSI drop in inflation pressure results in a 0.2% reduction in fuel
economy. In effect, your car consumers 3-4% more fuel than it ideally
should if all four tyres are underinflated by as less as 5 PSI.
Hence, it is imperative that
you check tyre pressure periodically. You can use an off-the-shelf
pressure gauge to examine tyre pressure at home. Better still; seek
professional assistance at any local garage that offers services for
car
tyres in Dunham.
Wheel Alignment
Wheel alignment is another
crucial factor that affects the fuel economy of your car. According
to automobile experts, misaligned wheels can lead to a 10% increase
in the fuel economy of your vehicle.
Wheel misalignment is not the
easiest thing to detect. Its signs are subtle and often go under the
radar. Only the keenest of drivers can recognise wheel alignment
visually, which is why it is essential that you take your vehicle to
North East Tyre Services for an effective wheel alignment service.
They will also check the overall condition of your tyres and offer
other necessary services like wheel balancing and general car
repairs.
Nevertheless, you’ll do well
to acquaint yourself with the most prominent symptoms of wheel
misalignment-
-
Uneven tread wear, especially at the edges.
-
The car pulls to one side, mostly after you take a hard turn.
-
Your steering wheel is off-centre. Notice the carmaker’s logo at the middle of your steering wheel. If it’s tilted even when you are driving straight, there’s an issue with the wheel alignment.
Wheel Balance
The even distribution of mass
throughout the tyre body is paramount for a smooth driving experience
and optimal fuel efficiency. Unbalanced wheels leave alternating
heavy and light spots on the tyre body, resulting in constant
vibrations of the vehicle. It ultimately puts extra pressure on the
engine, and subsequently leads to higher fuel consumption.
Wheel imbalance can contribute
to a further 3-4% increase in fuel consumption. Unfortunately, it can
neither be prevented nor rectified at home. You have to subscribe to
the service of an automobile workshop specialising in Car
Tyres Dunham.
You can easily save quite a
few bucks on fuel if you pay close attention to these aspects of your
cat tyres.
As they say, a penny saved
is a penny earned!
