My MINI came wearing those MINI "Lite" wheels and a set of Pirelli P-Zeros.
In prepping to whoop some Challenge butt, I just swapped them for V710's mounted on a set of stock style "Holies".
Just for E36 M3s and grins, I put the car on the race scales before and after.
Net savings on the wheel and tire combo only?....
....65 lbs. 
Rotational weight. Good grief, I can't believe how fat those "Lites" are.
