Re: Which treads have an advantage?

I've seen people say this so many times that I just can't take it any more. Unless you are talking about team shirts or forum discussions there aren't any threads to be discussed here. The matter at hand is treads (like referring to tank tracks) and more specifically tread (singular) referring to the traction enhancing material attached to the surface of a wheel. Thank you.

Now for rough top versus wedgetop, I would second most everything said above. Also, I don't think anyone has done any real testing between the two to determine which is better so most of it is probably just hearsay.

The wedgetop one does seem to be more popular. It does seem though that wear seems to be directly proportional to ground pressure which is inversely proportional to width. On wheels with 1.125" wide wedgetop we experienced no detectable wear whatsoever on carpet over the course of practice and one regional. However teams with .75" wide wheels with wedgetop have been known to have lots of wear and have to replace the tread during a regional.

One question that came up between a few of us is which way to run the diamonds with wedgetop. Because the diamonds are not simply rotated squares, they have a long diagonal and a short diagonal. So, what are the differences between running the diamonds long diagonal parallel with the circumference line and running the diamonds with the long diagonal perpendicular to the circumference line? Does anyone know? In a way I doubt that anyone really does know or has tested both ways
