The
route to lower operating costs with
Tyre Pressure Monitoring and
Management Systems
Why Monitor Tyre Pressures?
|
| Fuel
ecomony |
On
average, tractor tyres were tested 10%
underinflated, whilst trailer tyres were 15%
underinflated. This has a considerable effect on
fuel consumption. (Source: Continental Tyres) One in five
tyres is underinflated by up to 40% (Source:
Schrader Bridgeport)
Fuel
represents over 52% of a rig's running costs and
30% of its total operating costs. (Source:
Motor Transport)

| Improved
tyre wear |
Running
tyres at 20% underinflation can reduce tyre life
by up to 50%. (Source: Goodyear) Almost all
tyre debris seen on motorways comes from the
inner tyres of dual axles.
Tyre
disintegration is virtually always caused by
tyres being under-inflated. (Source:
Tire Retread Bureau)

| Safety |
Proper
tyre inflation would save 25,000 lives per year. (Source:
NHTSA) |
| Reduced
maintenance costs |
Maintaining
tyre inflation pressure is the most important
tyre maintenance function. Cost per mile benefits
will directly result from good tyre pressure
control. (Source: Goodyear Tyre and Rubber) |
| Performance |
Running
on low pressures is like driving with your foot
permanently on the brake pedal. For truck
tyres, a 70kPa drop in tyre pressure will
increase tyre rolling resistance by 2%. (Source:
Goodyear Tyre and Rubber)

| Reliability |
How
much does it cost you when a delivery is missed
through tyre failure? |
International independent research has shown that,
on average, only 17% of tyres are correctly inflated*. A
minor under-inflation of only 140kPa results in an
increase in tyre wear of at least 20%, and an increase in
fuel consumption of 5%**.
So, if a 12 wheel rig has tyres which are under-inflated
by just 140kPa, and it burns R80,000 of diesel a year,
with Tyreshield its operator could save:
Fuel
Saved
(5% of R80,000) |
R 4,000 |
Tyre Wear Avoided
(Tyre cost: 25c / ave. 80 000 km / yr
travelled = R20,000 x at least 30% less tyre
wear) |
R 6,000 |
| Total Savings |
R 10,000 |
For less than R 9,500, a Tyreshield
system would save all that expense,
uncertainty and inefficiency year after year.
Then there are the very real additional costs of:
Accidents
- the majority of "blowouts",
tyre shredding and commercial vehicle fires are
caused by tyre under-inflation, not cheap tyres.
Maintenance
- imagine what you would save if you did not have
to regularly check every tyre on every vehicle?
Insurance
- early indications suggest that insurance
companies would be prepared to discuss premium
discounts if a reliable tyre pressure monitoring
system was fitted to a truck or bus.
Reliability
- a puncture is always an expensive business, but
when tyre failure means missing a delivery, the
costs can be crippling.
