Ya, your reading it correctly. Looks like the center bore of the wheel is very close to the dia. of the Taco's hub..a very good thing...so you did not have to use hub centering rings, no?
Also, I really like the DTs and my only major hangup with pulling the trigger on them has been their weight since the high altitude so zaps my power. Did you notice any substantial drag, rolling resistance or any more effort coming off the line?
