The trend towards larger wheels and lower profile tires, not just in the aftermarket but with manufacturers, is a sad state of affairs. One would think we'd be trying to conserve energy at this point, for any number of economic and political reasons, but it's hard to find any real signs of it yet. It's even worse when a manufacturer puts big wheels on a new car, and then fills up the inside diameter with bigger brakes. There's no going back to 15 inch wheels without a major brake reconfiguration. That vehicle is stuck with big wheels for its whole life - and the poor ride, expensive tires and poor fuel economy that comes with it.
