automated tyre pressure monitoring reduces your costs!
EXEMPLARY ROI CALCULATION:
Articulated vehicle with 4 x 2 tractor unit, 3-axle semitrailer, short and long distance traffic,
80,000 km / year. ø consumption 38 l diesel / 100 km, ø tyre price approx. 400 € / tyre.
Tyre mileage at optimum inflation pressure, approx. 200,000 km.
Fuel savings (assumption according to Conti)
10 % reduction of tyre rolling resistance results in approx. 4 % savings in fuel.
1 litre of diesel consumption is equivalent to approx. 2.65 kg CO2 emission.
Tyre underinflating of approx. 1 bar results in approx. 4% increase in rolling
resistance = 1.6 % increased consumption = 0.6 l / 100 km = 480 l / year fuel
saving / year = 800 x 0.6 l / 100 km x 1.60 € / l Diesel = 528 € / year.
Inflation pressure influence on tyre wear (according to Michelin)
12 % tyre underinflation = 5 % tyre performance loss: thus,
12 tyres x € 400 x 5 % = € 240 tyre costs due the loss in performance.
Avoiding tyre failures
ø 2 tyre failures in 5 years, ø costs of the breakdown service in Europe (according
to Michelin Euro Assist) approx. € 1,000 / breakdown (not including costs for late
deliveries and possible penalty payments)
Investment / costs for equipping with sens.it HD (for 5 year period)
|Total savings over 5 years||3.520 €|
|Fuel savings over 5 years||2.640 €|
|Tyre cost savings (2 sets in 5 years)||480 €|
|Savings from tyre failures avoided||2.000 €|
plus the reduction of 1.3 t CO2 emissions / per year and tractor!
