Estimated cost comparisons after first tyre life based on (I) internal mileage data collected by Michelin salesforce between Jan 2018 and April 2022 in Europe and mileage estimation based on tyre design characteristics in main usage on motorways and national roads, (II) VECTO calculation of fuel savings, (III) average sell out tyre price on European replacement market:
- 594€ for 315/80 R 22.5 MICHELIN X® LINE™ ENERGY™ Z & D tyres, 603€ for 315/70 R 22.5 MICHELIN X® LINE™ ENERGY™ Z2 & D2 tyres) and (IV) average price for tyre mounting operations (25€ for deposit). Indicative price of 1.65€/l based on CNR’s professional price index of gasoil in March 2022 in France without VAT.
- 508£ for 315/80 R 22.5 MICHELIN X® LINE™ ENERGY™ Z&D tyres, 515£ for 315/70 R 22.5 MICHELIN X® LINE™ ENERGY™ Z2 & D2 tyres) and (IV) average price for tyre mounting operations (21.39£ for deposit). Indicative fuel price at 1.42£/L based on Globalpetrolprices.com in June 2022.
- Tractor 4x2 + Semi-trailer 3 axles fitted with 385/55 R 22.5 MICHELIN X® MULTI™ T2
- Certified VECTO tyre rolling resistances
- Comparing the following tyres: 315/80 R 22.5 MICHELIN X® LINE™ ENERGY™ Z/D and 315/70 R 22.5 MICHELIN X® LINE™ ENERGY™ Z2/D2
- Results may vary according to load, road, weather and driving conditions
Estimated CO2 savings:
Material savings linked to fuel consumption:
Gain in fuel consumption in litres x 1000 (to obtain the result per 100,000 km) x 3.24 (a)
Material savings linked to tyre consumption:
Tyre cost / €600 (b) x 70kgs (c) X 2.3 (d)
(a) The emission factor of 3.24 kg CO2 for 1 liter of diesel comes from life cycle analysis calculations made by ADEME for pure diesel. It includes emissions from the production of diesel (17%) and from its combustion (83%). Source: ADEME, "Well to Wheel – JEC" study, v4, July 2014.
(b) The average selling price of a tyre on the European replacement market is €600.
(c) The average weight of a new tyre is 70 kg.
(d) The emission factor of 2.3 kg CO2 for 1 kg of tyre is based on calculations of the life cycle analysis of the production of a tyre (known as ‘cradle to gate’), carried out internally by Michelin according to the calculation rules developed by the tyre manufacturing industry (via the global organisation Tire Industry Project - TIP - bringing together 10 tyre manufacturers on sustainable development issues). It includes the stages of raw material extraction, transport, manufacturing and distribution.
