One easy solution to the wear problem is to periodically rotate the wheels between ends/corners/etc. In our application, an 8WD with .090" drop on the center two wheel pairs, we've found that the rear most pair and the rear center pair wear the fastest (under the center of mass), the front center pair wears a bit slower, but not by much, and the front wheels barely wore at all. The simple solution was swapping the front and rear wheel pairs between our week 1 competition and week 3 competition. Luckily, our drive is set up in such a way that it allows for wheel swaps in less than 2 minutes or so.

Yeah, Understandable.

It's not a quick thing to change out wheels for us, probably about a 20-30 minute time frame. I was thinking about buying a pair and making the secondary chassis of this years bot with the vex wheels. The 2013 chassis is the best one we have made and we have spares of just about all pieces.

Are you running 8wd?

Thanks for the information.
