New sensations, best tires for electric cars
Acceleration, braking, torque, noise level... driving an electric car offers a brand-new experience. A simple test-drive and you’ll feel like you’re on a flying carpet, with only the sound of the wind and the tires for electric cars in the background. A champion of sustainable mobility for both road and track, Michelin has long been exploring electric vehicle tire technologies, notably via its involvement in Formula E, which it has been a partner of since its first season in 2014. High-level electric competition has served as its development and technology-transfer laboratory, particularly in the field of energy efficiency to offer the best possible tires for electric cars.
The range challenge of electric cars
The future of electric vehicles is in part dependent on their range, which is a major factor driving public adoption. Range can be extended by opting for a more energy-efficient driving style and using regenerative braking whenever possible. But that is not enough. So car manufacturers are investing heavily in Research & Development programs to create ever more efficient and energy-dense batteries. But the downside is that batteries are becoming heavier and heavier, which in turn leads to accelerated tire wear. For tire manufacturers, this represents a double challenge: tires for electric cars need to carry heavier loads while still providing excellent longevity. Michelin successfully rose to the challenge by developing two tires: MICHELIN e.Primacy and MICHELIN Pilot Sport EV.
MICHELIN tires for electric cars: boost the range of your battery
With its high elasticity elastomer, the MICHELIN e.Primacy tire delivers excellent performance in the EV category in terms of both longevity and rolling resistance. It increases the range of an electric car by 7%(1), equivalent to an extra 30 km on a 400 km trip. Which can prove very useful at the end of a trip when one needs to reach the nearest charging station. The MICHELIN Pilot Sport EV tire, designed for sportier driving, offers extremely low rolling resistance thanks to its GreenPower Compound technology, resulting in a 60 Km(2) range increase. For drivers wanting to make the most of their vehicle’s potential, this energy efficiency improvement - thanks to electric car tires - can really make a difference.
Sporty driving goes electric!
They say that electricity travels at the speed of light. One thing’s for sure, the acceleration of a high-performance electric car can be truly explosive if it has the right tires for electric cars fitted. MICHELIN Pilot Sport EV is a street-legal electric car tire, designed for sporty driving and developed leveraging Michelin’s experience in Formula E. It is capable of handling the extreme acceleration and mass distribution typical of these vehicles. The MICHELIN Pilot Sport EV tire accomplishes this thanks to its ElectricGrip Compound TM technology, which makes use of high rigidity rubber. Suitable for sporty driving when tires are worked hard, it provides optimal grip in both dry and wet conditions. Thus, the MICHELIN Pilot Sport EV tire delivers lots of driving fun while guaranteeing performance and safety.
From cycle racing to e-bikes
Today 1 in 5 bicycles sold are e-bikes. Michelin meets the needs of cycling enthusiasts with its Ready range of e-bike tires. The MICHELIN PROTEK model features excellent ruggedness and grip, for a safe ride through town in all weather conditions. For e-cyclists, this means fewer punctures and better electric assistance.

What to do with a punctured tire?
If you have a punctured tire, it may be for a number of reasons. Often, inflation pressure loss is a consequence of a tire puncture, or tire sidewall damage, but it could also be a leaking valve, valve cap or even the wheel. So what should you do when your tire goes flat? Let's get to the heart of the matter.Learn more
(1) Greater range and lower CO2 emissions – New, the MICHELIN e-PRIMACY tire offers an average of 2kg/t less rolling resistance than the competition, equivalent to a fuel saving of up to 0.21L/100km. This corresponds to a 5g reduction in CO2 emissions for a VW Golf 7 1.5 TSI, and a 7% increase in range for a VW e.Golf. Rolling resistance tests, conducted on machine by Applus Idiada on Michelin’s request, in June (new tire) and August (2 mm buffed) 2020, on dimension 205/55 R16 91V.
(2) Better range for high-performance electric vehicles –In-house rolling resistance study, carried out in 10/2020, on dimension 255/45 R19, comparing the MICHELIN Pilot Sport EV tire (6.47kg/t) to the MICHELIN Pilot Sport 4 SUV tire (8.8kg/t). For an electric vehicle weighing 2,151kg, with a range of 540km, this difference of 2.3kg/t results in a range increase of over 60km, equivalent to a 10% improvement over the original range.
