what are you switching from. I can tell you that when I go from my 17' stockers that weigh maybe 25 lbs to my 19" HP evo's that are much heavier, I loose 3-4 tenths.

3-4 tenths is a lot, i've always heard that 100lbs is a 10th. So your talking 3-400lbs. But i guess it would affect the gearing too, either way that's still a big drop just for tires and wheels

100 per tenth for sprung weight. Unsprung weight that teh motor has to spin is far more detremental to HP loss to teh pavement. Not sure of teh exact calculation but my 19's are a good 14 lbs heavier per wheel.
