whats the definition of 2 piece wheels?
 

ive got some wheels i think are 2 piece wheels. they are eneki wheels, and they have a split between the center and the wheel part, all the way around, the center is welded to the wheel all the way around on the back side. there are 'fake' plastic bolts in holes too :) would this be considered a 2 piece wheel since it was once 2 pieces, and the center was forged and then welded onto the actual wheel, or does it have to actually be bolted onto the wheel?

thanks

From tirerack.com's Wheel Tech section:

"Some 2-piece wheels have the center bolted into a cast or cast/spun rim section and other manufacturers press centers into spun rim sections and weld the unit together."

So you've got 2-piece wheels.

Ive got 3-piece wheels I never understood what the 3rd piece was
they are Volk CV pro rim, bolted to the center part, then i have a screw on center cap, and a spacer. ???
