Agreed. I cannot see that being possible

The larger a rim tire setup is the larger the circumference of the tire is. By haveing a larger tire the driveshaft to rear wheel rotation ratio changes. So having say 22" compared to 17" the driveshaft would have to rotate more to turn the tire resulting in more load on the drivetrain. Take trucks for instance... If you put bigger tires on it you get worse gas mileage

Lol, thinking theoretically and at the extremes.

Well... A dynamag wheel would be over a stock one... But I doubt he had 6000$ for runs haha. Full cf wheels.

But the extra weight between the two would also factor in, so with my theory there are two variables to consider if you are trying to simply increase your economy.
No, a bigger rim will hurt mileage. When you make a wheel bigger you end up gearing the car up and the engine needs to work harder. If you go to bigger rims (heavier) or taller tire expect a slower car and worse mpg. A heavier rim also has a huge effect on braking performance. A guy with 20s on an accord here went through a red light and killed someone. An independent demonstration waa set up and they found that a stock accord did 100kph- 0 in 139 ft. same car same conditions with the same 20s took 211ft to stop. Scary **** man...

It's true, the bigger the rim the bigger the effect on braking and acceleration. You tire circumference also matters. You can keep the same circumference throughout the rim range thus keeping your stock gearing. Per example. My car has 205/65 r15's stock but a 245/45 r17 is the same height it's just an inch and a half wider. So the final drive isn't effected but the added weight from the bigger rim and wider tire can cause acceleration/braking decrease and widen your turning radius.
