Changing the size of your rims should have no effect on milage. Any milage change would be a result of changing the model of tire and/or using different pressures.

Weight is only a factor when accelerating. Add more weight will require a bit more energy to get up to the same angular velocity.

Also to note: If you save weight by getting a smaller rim you probably have to add weight by getting a bigger tire.

 

The difference in weight between different wheels and tires isn't enough to affect your gas mileage significantly.

 

alright cool that sums up my questions
