I have 2017 Premier Volt. I hit a big rock on the freeway that rolled into my path after another car in front of me hit it, so I had no time to react. Anyway, it created bubble into each of the two right tires. So I brought the car to the dealer and told me that I can safely drive it for 5,000 more miles. That distance is up. And so I had all my tires replaced, and decided on the Continental TrueContact

And there's a running discussion on it here:

The stock tires that came with my Chevy Volt is Michelin A/S.
The new tires only lessened the road noise slightly and it doesn't squeal easily if I floor it. So far been very satisfied with the way it handles. I still have to evaluate it during the rains.
And here's the actual loss of efficiency in the first run compared to my old stock tires. Since I only traveled 45 miles, I used the MPGe readings
Loss of range = (118 MPGe - 112 MPGe)/118 MPGe x 100% = 5.1% loss.
Which is not bad. Perhaps another 2,000 miles and it would be back to the same efficiency.
The tire shop told me that my other two stock tires are still good for another 5,000 miles and so I kept them and will use them as spare for long trips. Will just have to purchase wheel from car recyclers.
