quote: Italian tire maker Pirelli is predicting that over the next decade or two standard tires will change to really tall (>20" rims) narrow tires that look similar to the wagon wheel inspired ones used on early cars. Doing this will let them make the tires significantly narrower (for reduced drag/rolling resistance leading to better fuel economy) while maintaining a similar size contact patch so that traction remains similar to current tires.
quote: Just wondering, what is the advantage of larger wheels? Is handling that much better? Won't tires be much more expensive, and the ride quality worse?
quote: Why not offer it without leather and the same wheels as the Eco which are only 17 lbs apiece?
quote: This is GM's first foray into a compact diesel in the U.S. in quite some time, and they're being cautious. They want to make sure that they hit their target market on the first go round, and not be stuck with a lot full of unsold stripper diesels that no one wants.
