Powerloss due to rotational weight and stuff
Ok I have a question.
How much power am I losing by inceasing my wheel weight by 4lbs per wheel?
My new rims are lighter but the rubber is heavier, so my OEM wheel set up is 32lbs with rubber and the OZ rim with rubber is 36lbs. Is there any way to figure out what kind of powerloss I'm experiencing.

another thing to factor in is the distance from the hub the weight is. Its easyer for a mass closer to the center to spin than one that is further away from the axis. ie, bigger wheels are that much worse compared to a smaller wheel of the same weight

Is this what you're looking for?
Formulas for tire size & their effect
effective ratio = (old tire diameter / new tire diameter) x original ratio
actual mph = (new tire diameter / old tire diameter) x actual mph
But I think this is what you are looking for, check the bottom of the page:

ummm errr I'll have to work that one out.
I just remember an equation to figure it out... it came out to something like 1lb of rotational weight equaled like 90lbs of unsprung weight. something wierd like that...
