Michelin is the “Official Tyre Partner” for the FIA Formula E Championship racing series and, as befits a official tire partner, prepped special tires for Formula E cars.

First of all, the tires will be all-weather, all-temperatures, so optimum performance must be achieved in both wet and dry conditions (no separate slick or wet-condition tires will be used in the racing series). This requirement comes from the need to reduce overall costs and the desire to promote sustainability.

Pascal Couasnon, Director of Michelin Motorsport stated:

“We designed the tires to be both energy-efficient and more like road tires. As a consequence, the new FIA Formula E Championship will serve as a life-size laboratory that will help Michelin to prepare its tires of the future.”

Nicolas Goubert, Michelin Motorsport’s Technical  Director, added:

“In ordinary traffic, no drivers use slick tires on their road cars, not even sporty road cars! The FIA Formula E Championship will use street circuits in city centres, so our aim was to design tires with tread patterns. The closer we are to the realities of everyday motoring, the more relevant and also speedier the carry-over of technology from the race track to road tires becomes.”

Secondly, the tires must be more durable than typically used in racing because, for each event, drivers will have just three sets of tires for both of their cars (6 sets of tires total) to cover free practice, qualifying and the race. This further reduces costs compared to other racing series where dozens of sets of tires are used.

Then we have size. Spark-Renault SRT_01E cars will be fitted with 18-inch treaded tires. The high diameter, together with low profile, will increase the energy-efficiency, extremely important for electric cars.

This corresponds to the real world. When we for example we look at the new BMW i3, it too has high diameter, low profile tires to increase range.

Good article Mark.
The video says that a the formula E tire is lower profile than the regular gas racer formula tire.

I would think both the gas AND the electric formula tire would benefit from lower profile. Is there a trade off here that I am not understanding?

Aerodynamically, higher profile tires (smaller wheels) are typically more aerodynamic and the tire/wheel combination is typically lighter than lower profile tires.

But lower profile tires tend to be more responsive to cornering inputs and directional changes as the tires are stiffer.

F1 tires are high profile because apparently the regs require a 13″ wheel for a number of reasons. In every other racing series you see a tire/wheel size more like the one you see here in Formula E.
