RPM/fuel economy/performance? I have a 2007 Hyundai Accent, 5 speed standard trans., with 14 inch tires. I posted a question here about the RPM level at 75 mph and got good responses. My car came with 14's, but the car can be equipped with 14 inch to 16 inch tires. If I change mine to 15 or even 16, would it noticeably reduce the RPM, and how would it affect the fuel economy/performance of the car? Just wondering what the tradeoffs were, and if it was worth the expense. Thanks
