Increasing fuel prices… how to manage?

All companies in the field of transport confirm: "The rise in fuel prices systematically weighs on comptes operating accounts " as fuel, on average, represents between 18 et 24 % of company spending.

From all of the factors influencing fuel consumption, one third of all full tanks are directly absorbed by the rolling resistance of tyres used on motorways.



Interested by fuel savings?

This is why Michelin recommends the use of tyres with low rolling resistance which could save you approximately 1 litre per 100km for the life of the tyre.

And yet… could tyres, rolling resistance and fuel consumption all be related? Yes. Overview:

Technical file

What is "rolling resistance?" Why does it influence my tyres and therefore my fuel consumption?

It’s a fact : to travel on land, you need energy. To reduce fuel consumption, the impact of the forces opposing the movement of vehicles must be reduced (gravity due to the weight of the vehicle, air resistance, mechanical friction). Rolling resistance for tyres, often under-estimated, is the cause of one third of fuel consumption
>Observation
A smooth tyre on a smooth surface generates little or no rolling resistance, but has no grip.

Tread is therefore indispensable to ensure comfort and grip.
>A few explanations
The tyre must be flexible to ensure comfort and grip. It therefore changes shape on contact with the ground. To return to its initial form after each change, the tyre needs energy and some of this dissipates in the form of heat. This loss of heat is called "rolling resistance"
>Michelin research

Since 1992, Michelin has added silica to somme of its rubber compounds. This component reduces internal heat build up in the tyre without compromising grip and has allowed us to reduce rolling resistance by a factor of 3.

Facts and figures :

If the 6.5 million tractors, semi-trailers and autocars, in Europe, were equipped with Michelin Energy tyres, the planet would save the equivalent of 400 fuel tankers or 20 000 tons of fuel.
The future :

Tangible proof that Michelin is taking an active role to guarantee a better mobility of transport, while preserving a better future.

 

Impressive

Up to 2 Truck tyres free Thanks to fuel savings made by using MICHELIN A2 ENERGY Truck tyres

Research :

MICHELIN tyres with low rolling resistance :

BECAUSE ONE THIRD OF FULL TANKS ARE LOST THROUGH YOUR TYRES, WE DESIGNED THE MICHELIN A2 ENERGY. RANGE

The MICHELIN A2 ENERGY Truck range has a rubber mix allowing 1 litre of fuel to be saved per 100Km* while maintaining both grip and safety properties and an excellent life cycle.

* Average savings over the life cycle of a tyre.

How can MICHELIN A2 ENERGY tyres ensure your fuel savings ?

    • Thanks to the rubber mix used, which minimises the loss of energy
    • Thanks to the specific structure of the tyre. This reduces the changes in shape for the tyre in each rotation.
