Now that you mention it, I noticed that as well. I had a chance to compare the Pilot Alpins to the Turanzas when I had the tech swapping them for me, and the Bridgestones seemed much heavier. The Artic Alpins I had for my 318 were even lighter, I was afraid if I left the door to garage open that they would get carried away with a gust of wind!geomax said:One interesting thing about the Michelin Pilot Alpins - they're pretty light for a tire. I was surprised when I picked one up. I'm not sure of the exact weight, but my guess is under 18lbs a piece. The Dunlops are much heavier by comparison.
