etyres Green Policy suggestions to reduce the
impact of motoring on the
environment
The environmental damage caused by cars in the UK is huge and
unless we all react without delay the long term effects will be
disastrous. It is inevitable that our government will seek to
reduce the demand for fuel by raising fuel tax so the cost of
motoring is certain to keep heading skywards. Fortunately there
are some simple things relating to tyres that you can do to save
money on fuel costs. Follow these tips to help make your car go
further between fills at the petrol pump.
Inflate tyres correctly
Keeping the tyres correctly inflated is vital. Tyres that are
low on air pressure have greater rolling resistance. That means
your car’s engine works harder, using more fuel.
Correct tyre pressures will also ensure safer, more secure
handling and better tyre life. Check your tyre pressures once a
week. Make sure that they are cold when you do this.
You can find the correct tyre pressures for your vehicle in the
owner’s handbook and on the tyre placard (normally found on the
inside of the glove box door, on the driver’s door opening or
fuel filler flap). These are the minimum tyre pressures.
Setting the pressures slightly higher will normally improve fuel
economy. However do not deviate greatly from the manufacturer’s
recommended pressure for your tyres. We estimate that a 12.5%
deterioration in rolling resistance efficiency would be caused
by allowing a tyre with a correct pressure of 35 psi to reduce
to 28 psi.
Use energy saving tyres where possible
Most major tyre manufacturers now produce a range of low
resistance tyres. These tyres are primarily designed to save
fuel but the other important effect is the resulting reduction
in CO2 emissions.
The effect of using these tyres is significant. For a driver
with an annual mileage of 25,000 miles and a fuel consumption of
35 mpg the reduction in emissions would be almost half a ton of
CO2. (See the case study at the end of this article.)
Obtain the maximum mileage from your tyres
Each year hundreds of thousands, if not millions of tyres are
changed prematurely. An entire industry revolves around selling
“part worn” tyres! The reason for this is partly entirely
genuine and partly the result of downright fraud by unscrupulous
tyre retailers. The impact on the environment is, however, just
the same; more waste tyres than necessary.
If a car is booked in for a routine service and the Service
Manager notices that the tyres are within a few thousand miles
of being worn out he will, quite properly, recommend that they
are changed. His job is to make sure that the car is safe and
legal until the next service. However this obviously means that
the tyres are changed a few thousand mile too soon. This factor
costs motorists millions of pounds every year and has a big
impact on environmental pollution due to the unnecessary number
of waste tyres.
The other factor involved in the premature changing of tyres is
the illegal “overselling” by unscrupulous tyre retailers. Many
large chains have a management structure that places sales
pressure on branch managers to sell tyres wherever possible,
regardless of whether or not they are needed. This causes
massive unnecessary cost to motorists and huge environmental
damage.
etyres has a completely different structure and we frequently
refund payment to customers who have ordered and paid for tyres
that are found not to be needed. On literally hundreds of
occasions each year our local colleagues arrive to fit four
tyres that our Customer has ordered and paid for, only to find
that only two tyres are needed. It is always a pleasure to
refund half the cost. We are also pleased to help in keeping the
number of waste tyres to a minimum with the resulting reduction
in environmental damage.
Check the wheel alignment
Your car will also be more energy efficient if the wheel
alignment is correctly set and the brakes aren’t dragging. Again
it’s a case of less rolling resistance. etyres recommends that
the best place for alignment is the vehicle manufacturer’s main
dealer. However our tyre fitters will check your old tyres for
signs of abnormal tyre wear and advise accordingly.
Drive economically
- Driving techniques and a little planning can make a big
difference to how much fuel you use and the resulting CO2
emissions and not least the wear on your tyres.
- Drive smoothly, look ahead in traffic and try to
maintain a steady speed – the more you push your
accelerator, the more petrol you’ll use, the more CO2 you
will pump out and the more you will wear out your tyres.
- Use the gearbox sensibly – driving in a lower gear than
necessary and revving the engine hard wastes fuel, so change
up through the gears as soon as practical, but not so the
engine labours.
- If you drive an automatic, ease back slightly on the
accelerator once the car has gained sufficient speed – the
automatic gearbox will shift up through the gears more
quickly.
- Avoid peak hour and other heavy traffic where possible –
see if you can reschedule your trip to an earlier or later
time, or use an alternative route to avoid congestion.
However, keep your mileage to a minimum to avoid unnecessary
emissions and wear on your tyres.
- Avoid engine idling for long periods, where possible –
if you expect a lengthy delay switch off the engine. This is obviously a very efficient way to keep emissions low!
Driving economically
You’ll use less fuel, reduce CO2 emissions and save wear on your
tyres.
-
Drive more slowly – travelling at 50 mphh rather than 60 mph
will reduce fuel use by up to 25% also reduce wear on your tyres
and the amount of CO2 you pump out.
-
If your car is fitted with a cruise control, using it during
highway driving will help to maintain a steadier cruising speed,
and smoother driving saves fuel, tyres and CO2.
-
Use your car’s air conditioner sparingly.
-
If your car doesn’t have air conditioning, keep the windows up
and use the ventilation system when travelling over about 50
km/h - travelling with the windows down over 50 km/h increases
the car’s aerodynamic drag.
-
If your car is an automatic with power and economy modes use
the economy mode to ensure the transmission up-shifts earlier.
Sensible driving techniques also help reduce wear and tear on
your car’s brakes, tyres and the other mechanical parts. So
you’ll save money on running costs for your vehicle as well as
keeping emissions as low as possible.
Care for your car and save
Proper servicing and maintenance of your car will help to ensure
its longevity and reliability. It will also help to keep it
running at its most efficient: that means less fuel use and less
air pollution.
To care for your car, it’s important to:
-
Keep the engine correctly tuned
-
Keep filters in good condition
-
Keep the fuel and ignition systems operating correctly
-
Regularly change the engine oil using the correct grade of oil
as recommended by the manufacturer
Use your car less
The less you use the car, the less fuel used. So it’s worth
considering alternatives such as public transport, car pooling,
walking or riding a bike. Ask yourself if the trip is really
necessary. If you must use your car, try to combine a few
smaller trips into one. A cold engine is less fuel-efficient and
emits more pollutants than a warm engine, so several shorter
trips will use more fuel than one longer trip.
Also, if you have more than one car, save fuel and use the
smaller more fuel efficient one, when practical.
Case Study
’Green’ tyres offer dramatic fuel savings for high mileage
pharmaceutical fleet.
ONE of the UK’s leading companies has estimated it could cut
almost £200,000 a year off its car fleet fuel bill by switching
to energy-saving tyres.
Pharmaceutical and chemical company Bayer carried out parallel
tests on its 1,300-strong fleet comparing Michelin
Energy tyres to the tyres originally fitted to two cars. A
Nissan Primera covering more than 70,000 miles and a Volvo V40
SE running for 20,000 miles were fitted with the Energy tyre.
The test vehicles delivered a fuel consumption improvement of
7.7% against one brand and 3.7% against the other.
Projections show that with 80% of Bayer’s fleet of 1,300
vehicles eligible for Michelin tyres the potential saving would
be nearly £190,000.
Tread wear recordings taken at the same time also showed the
Michelin Energy tyre gave more than 25% more mileage,
potentially saving Bayer a further £41,000 a year and reducing
purchases by nearly 700 tyres.
Fleet administrator Andy Regan said: "Our tests showed that
Michelin Energy gave a substantial fuel saving, an equally
impressive increase in mileage and consequent saving in tyre
purchases."
The Newbury-based company operates petrol and diesel models
running on a four-year/60,000-mile and four-year/90,000-mile
lifespan respectively.
