Speaking of X-1's, Michelin no longer mentions anything in their X-1 brochure along the lines of saving gas. What is the likely improvement in MPG versus a tire like the energy MXV4 or the Pirelli? I heard "5% to 7%" improvement, but of what??? Is that 5% better MPG, or 5% less rolling resistance? Are the Pirelli's just as good? On MY car that would save about $750 gas over the 10 years I plan to keep it...thus paying for the tires and then some. The Pirelli's wouldn't last as long, but they cost a bunch less too, so it could be a push. It's a great time to be alive, dontcha think?...it's like trying to decide between chocolate and vanilla. It's probably tough to make a seriously bad decision at this level. So the question remains: how much better (or worse) is the rolling resistance of the X-1? Is this hype?
