I got new Yaks and I added a small peg to the front of my scoot today, haven't had a chance to test it though yet.
Oh - and my camera is tempremental, apologies for the blurry first pic.

Not really, because if that were true people wouldn't bolt thier T bars to make them less likely to hit thier knees on it.
Besides, an axel sticks out perhaps 1cm on either side.
I dunno, if I had a drill I'd try it out on an old scoot I have.
I think he means that the black rims are too small, thus the pressure of the urethane is spread over a smaller surface area than that of Yaks etc, making it less durable.
