That said, let's talk about wheel weights.

I was surprised that the pizza pans weighed that much, actually--nearly 10 lbs of rotating mass. The OEM 15" Prius wheels weigh 16.3 lbs each, and the 195/65-R15 tires are 18 lbs. The lightest available wheel on Tirerack is a forged BBS 17", at 14.3 lbs, but its cost is prohibitive, more than $2000 for a set of 4, and the weight of 17" tires would more than offset the savings in the wheels. However, there are other reasonable options between 15-15.5 lbs for around $400/set in 15" diameter. Since I want to start autocrossing this car, what I might do is pick up one of those options with some 195/50-R15 Dunlop Direzzas, which weigh the same but are a couple inches shorter than the stock tires. That would give me a set of wheels for autocross a pound lighter on each corner and with the effectively shorter gearing of a smaller diameter to boot, and leave my OEM wheels and tires for daily driving, road trips, and the GGP road rally portion.
