176 used plaction wheels for the first time in 2011, and we noticed that the little edging that runs along the outside of the wheel that holds the tread in place started to snap off after our first regional. This, of course, eventually led to tread just moving sideways and falling off the wheels. We saw instances of this on all 6 wheels on our drivetrain. So, we ended up replacing all 6 wheels.

In 2012, if our drivetrain is conducive to the use of wheels which use tread, we will most likely use performance wheels. 6 x $36 is much cheaper than 12 x $26. Just something to think about. Of course, if you want to get into which wheel is easier to mount on a certain kind of drivetrain, see Akash's post above.
