I don't think the problem discussed above has to do with the normal tread wear properties. It probably has to do with your weight distribution. I'm going to guess you have most of your weight on the center wheel and rocked quite a bit during the match. And with a 1/8" drop the wedgetop on the corners would most defintely be scrubbing. Especially because wedgetop is a tiny bit thicker than roughtop (making the effective drop even less).

Let me know if I'm right.

Maybe, but I do know that wedgetop seems to wear faster than roughtop.

Re: Drive train wheels idea

Wedgetop wheels have narrow, tall ridges which means less of the tread transmits the same force compared to roughtop. This seems to fit the anecdotal accounts of wedgetop wearing out faster.

If wheels were a dirt road, roughtop wheels would be a dirt road where the cars pass over all of the surface evenly resulting in even ware; Wedgetop, on the other hand, would be a road where cars only travel down the center resulting in ruts in the road.
