So I've read somewhere (here? I forget) that the OEM LRR tires make a difference of ~10-15% efficiency compared to normal tires. But I've also read that the trade-off is in the form of almost no road grip, e.g., tires chirping when hard-accelerating from a stop in even ideal conditions. My hypothetical is: would changing to normal tires improve a Volt's performance? Has anyone done this and documented the results of a 0-60?
