Electric vehicle tire replacement

When I replaced 2 of the bridge stone ecopia tires with new ones next thing i know my miles per kwh was in the garbage.
Those first 2 days of driving was kind of scary.
I was running a very comfortable 4.5 miles per kwh, just replacing 2 tires dropped that to 3.7 miles per kwh.
Had I replaced all 4 tires it could have dropped to around 3 miles per kwh.
Had I replaced all 4 tires it would have been likely that:
If I bought the tires in the next town over I would not have made it home if I didn't stop and charge at the rental house or one of my friends.
If I didn't leave for work the next day with anything but a full charge I might not have made it back.
If I tried to go to the next town over and back with out charging, I wouldn't have made it.


Now 400 miles later I am back at 4.4 miles per kwh.
Running 38psi on new tires as opposed to 42psi on warn out ones is alright.

So look out for that tire break in if you have an electric vehicle you use to where you require most of its range.

Possible counter measure, buy 1 or 2 at a time like I did. The tire dealership will hate you if you buy 1 at a time and replace all 4 like that. But if you can just get it out of the way and buy at least 2 at a time.
