Prius CE28 ECO drive wheels

I'm actually looking to buy these - so far I'm told that a set of four 16x6 is going to be about 2 grand shipped. I'm not sure whether to get these or some other, wider rims considering tire choices (since the stock prius touring wheel size is so limited because it's a funny size). Also, I'm not so hot about the $400 increase in price (from a few months ago) due to the USD/yen exchange rate.

In terms of pictures, the only thing I could find were these two:

 

So these are Rays Volk CE wheels? What do they weigh? vs. Stock Touring 16's?

 

With tyres fitted would that make them lighter as there is less tyre on more rim? and less air volume, or am I being dumb?

See this thread below. It should improve the acceleration by 1 second as well.

For the 15" rim, Nokian I3 185/65/15 is 1lbs lighter than the OEM Integrity. I am not aware of any other tire that is lighter than OEM.

 

Anyone know of any lightweight performance-oriented summer tires I could put on these? I could really care less about ride quality, quietness, and tread life (no, no R-comps) but I don't want the all-seasons that other PCers like.

 

Bridgstone Ecopia's from Tire Rack.

 

Volk marketing magic. These are only for our car. Notice just how many different lug patterens you can get on this set? Think there is a set of Volks for every car made. For some there are 10-20 different sets(BMW) you can get all at #'s north of 2k. You do have to pay to lower unsprung weight and 10lb wheels are going to cost.

 

Check TireRack. They have weights for all the tires they sell.
