On our 2016 Leaf SL 30KWh, we ended up returning/exchanging a new set of Goodyear ElectricDrive tires due to loss of range.
Previous tires were the OEM Michelin Energy Saver, 215/50R17. They only had 19k miles (we bought the car used @3500 miles), with 5/32 tread left on one pair, 7/32 on the other pair. One of the better tires was ruined due to a sidewall cut, and they were all 6yrs old, so we chose to replace the whole set.
We put on the ElectricDrive tires in early November 2022, then switched to new Michelin Energy Savers right after Christmas after almost 500 miles. The drop in range on the Goodyears was too much to make our standard 75-mile trip without stopping to charge, in the current cooler weather (40's F) plus rainy conditions. Well, it was possible to make it in one go with some "white-knuckle hypermiling", e.g. limiting motor power to ~20KW, no heater, staying below 55mph, etc. But that's no way to live your life when different tires caused the change.
Here are our energy use measurements:
- 4.2 mi/kwh before Goodyears, 2yr avg, varying trips/seasons, 36-44PSI.
- 3.9 mi/kwh on Goodyears, std trip with hypermiling, 45PSI.
- 3.6 mi/kwh on Goodyears, std trip, no hypermiling, 50PSI.
- 4.0 mi/kwh on new Michelin Energy Savers, no hypermiling, 44PSI.
- 4.4 mi/kwh on new Energy Savers, hypermiling, 44PSI.
Switching back to the Michelins pretty much means we have our car back, for the purposes of this longer trip. The drop in range from the Goodyear ElectricDrive tires made the car impractical for this common use case, especially given that quick chargers in that area can be scarce and sometimes inoperative when you need one.
This was our experience, hopefully others will find the information useful.
