What is rolling resistance?
(1) Data collected on French motorways in 2000, during MICHELIN "Fill up the air" operations.
(2) MICHELIN e.Primacy category of tyres is defined as one of the Premium summer tyres such as CONTINENTAL, GOODYEAR,BRIDGESTONE, PIRELLI, DUNLOP brands, and which are not dedicated to Original Equipment application (i.e not designed to achieve car manufacturers specific targets) but tyres that can be purchased from retailers.
Rolling Resistance test - Rolling Resistance tests conducted on machine by Applus Idiada, on Michelin's request, June (on new) & August (on 2mm buffed) 2020, on dimension 205/55 R16 91V, comparing MICHELIN e.PRIMACY (new: 5.58kg/t & worn: 5.13kg/t) versus MICHELIN PRIMACY 4 (new: 7.74kg/t & worn: 6.25kg/t) ; BRIDGESTONE TURANZA T005 (new: 7.17kg/t & worn: 5.81kg/t) ; CONTINENTAL ECOCONTACT 6 (new: 6.39kg/t & worn: 5.49kg/t) ; CONTINENTAL PREMIUM CONTACT 6 (new: 8,93kg/t & worn: 6,94kg/t) ; DUNLOP BLURESPONSE (new: 7.97kg/t & worn: 5.54kg/t) ; GOODYEAR EFFICIENT GRIP 2 (new: 7.01kg/t & worn: 5.38kg/t) ; PIRELLI CINTURATO P7 BLUE (new: 6.96kg/t & worn: 6.30kg/t) ; PIRELLI CINTURATO P7 (new: 8.79kg/t & worn: 6.97kg/t).
(3) When new, MICHELIN e·Primacy generates 2kg/t on average Rolling Resistance less than competitors, equivalent in fuel consumption reduction of up to 0,21l/100km, equivalent of a reduction in CO₂ emission up to 5g for a VW Golf 7 1.5 TSI or equivalent of reduction of up to 7% in autonomy for a VW e.Golf.
During usage, MICHELIN e·Primacy generates 1,5kg/t on average Rolling Resistance less than competitors, reduction is equivalent of up to 80€ savings on fuel. This reduction is equivalent of up to 174kg of CO₂ saved. Usage reductions are estimated on the average of new and buffed 2mm data to take into account real life time performance -All reductions are estimated on a base of 35 000km and a fuel price of 1.46€/L (https://ec.europa.eu/energy/data-analysis/weekly-oil-bulletin_en 6/1/2020 weighted on the top 10 countries for motor vehicle movements on national and foreign territory - https://ec.europa.eu/ eurostat/web/transport/data/database). Actual fuel and cost savings may vary depending notably on driving habits, vehicle or tire pressure,
(4) Increased EV battery range and CO₂ reduction. When new, MICHELIN e.PRIMACY generates 2kg/t on average Rolling Resistance less than competitors, equivalent in fuel consumption reduction of up to 0.21l/100km, equivalent of a reduction in CO₂ emission up to 5g for a VW Golf 7 1.5 TSI or equivalent of reduction of up to 7% in autonomy for a VW e.Golf.
