Maybe if you are driving 50-55 on a nice day without AC on or any passengers? I have 22" Pzeros and I just did a small road trip of about 592 miles and got 445 Wh/mi going 80-85 avg with 90% highway driving.Anyone who's had both the Goodyear Eagles and the Pirelli Scorpions can comment on difference in efficiency? I have the Goodyear summers now and struggle to keep it under 400Wh/mile. Are the Scorpions significantly more efficient? Any other tire?
