The 2012 Nissan Leaf we used to have came out with ;
Bridgestone Ecopia EP422 (H- or V-Speed Rated)
I replaced them with P205/60R16 version of the same tire . The miles per charge came down . The miles per charge was slowly coming back uf as the tires broke in . Then the Leaf was rear ended & totaled .
I have read the miles per charge is greatest when the tire is just about worn out ( the rubber is thinner & has les " flex " ? ) & drops when new tires are installed .
Your guess is as good as mine ?
God bless
