The 22x9" is 37lbs. and I am not sure how much the tire weighs, but I would venture to say it is very close in weight to the stock tire (because of less sidewall). Of course with any 22 it isn't as "cushy" of a ride, but cornering in the car fells much more stable. It really sticks to the road and eliminates a lot of body roll. These wheels are actually multi-piece, and the rim portion of this wheel is spun-forged.
You can contact your local wheel and tire retailer and they will know more about the price for a package.
