Continental introducing Conti.eContact tire for EVs

Continental is introducing the Conti.eContract tire for EVs. Initially shown as a prototype at the IAA International Motor Show 2011, the Conti.eContact will be available in sizes 125/80R13 and 145/40R13 from this year.

Developed in co-operation with leading car manufacturers, Conti.eContact introduces new tire dimensions with a larger outer diameter, such as 195/55R20 instead of a traditional 205/55R16. This concept results in substantially reduced rolling resistance. A more flexible sidewall of the tire helps result in less energy loss when deflecting or rebounding.

Continental’s tire engineers started with a new approach to the Conti.eContact while still ensuring that the tire excelled at wet braking. Wide circumferential grooves, optimized tread depth, a flat contour and smooth off-shoulder design result in an extremely efficient and durable tyre for the electric vehicle market, the company says.

Unique sidewall lettering will also feature on the tire. The logo ‘BLUECO’ is aimed at connoting a series of innovative tyre technologies especially designed for the needs of electric vehicles.



The larger diameter 195/55/R20 would have enough room for higher power in-wheel e-motors and could be light enough if wheels are made of composites or new Dupont high resistance plastics.
