Averaging 1.5 mi/kwh @ 32 degrees down from 1.8 mi/kwh last year.

Averaging 1.5 mi/kwh @ 32 degrees down from 1.8 mi/kwh last year. As the title says efficiency has gone done by more than 15% compared to last year. This is highway driving, no preconditioning. AC set to auto 1 @ 65 degrees.

The only thing different is the set of tires. Last year still had the original OEM AT Dynapro tyres. This year I have the OEM Goodyear Wrangler all season tires which are supposed to be EV specific.

I thought the tires would be better for efficiency, so I am not sure why the efficiency is lower this year.

Is anybody experiencing something similar? As the battery ages, does it become less efficient? (As a system: coolant, pumps, cells, etc)

thanks

I can't find a Goodyear Wrangler intended for EV's?

Sorry it is too cold outside to take a picture . I found this picture of the tires on google.

you can see the ev specific denomination on the tire.

adding tirerack link for specs:

What tire pressure are you running?

The Goodyears are supposed to be at 42 based on the door sticker for the 24 trucks that have these new tires. My door sticker is different because it came with the Hankook Dynapro AT which is set at 36. Tire pressure is not an issue since I am running them at the higher pressure.

From all that I have read, it shouldn't be the mechanics of the truck, but software update??

Perhaps test turning off the auto climate control and use the manual controls to see if that has been changed by update.

Was the summer efficiency between both tires comparable? So many variables with cold weather its hard to tell. Even a slight headwind in cold weather has an exponential effect compared to warm weather headwind.

it was lower but not as noticeable around 3-5%

I’ll try playing around with it. I want to also check the battery and coolant temperatures.
