Sure, I'm very familiar with these Michelin Energy Savers because my prior car, a Ford Focus Electric used them. They are just top-notch on efficiency, which is why GM used them (to get the best EPA rating etc.) But I actually drive very little, I will never run out of range, so I don't care about efficiency. So I'm happy to trade-off efficiency for a gripper ride. If I used my Bolt for a daily commute I would definitely stay with the OEMs.
