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?
