Re: EV Digest, Vol 81, Issue 29

Electric Vehicle Discussion List mailing list
We had good results with the Bridgestone Ecopia tires on our 2012 Leaf
to replace the original all-seasons (we have a set of winter tires as
well which each do about half the year).  Kilometres per kWh increased
from 6.6 to 7.2 after the installation.

Regarding going to narrower tires, with the amount of rain, snow and ice
we have here, I would not want to reduce the contact patch area of my
tires.  I have tried the higher inflation, narrower tread in decades
past, and did not care for the impact on braking performance.  These
days, I expect spinning tires on acceleration would also become an
occasional issue.
