WCD 6" pneumatic tire wear

[Bob Steele]

The wear that we saw was not an overinflation issue in our opinion. We tested a variety of pressures and competed always on the low side.... These tires are very thin in the middle of the tread. We had pretty even wear across the tread...unfortunately the middle portion of the tread was not as thick as the outer sections. Automobile tires have nice even tread all the way across in thickness... and are quite different.

We had an 8 wheel configuration with a six CIM transmission.... there was a large amount of scrubbing going on in the two sets of inner wheels.

As an aside. Over the summer we substituted Colson solid rubber 6" wheels using the VEX hex inserts for hubs and they fitted almost perfectly and we are presently testing those vs the pneumatics on our practice robot. They work quite well...

This was something I noticed on 179s worn tires. While I do not know exactly what pressure they where inflated to, they all showed a similar wear pattern with the tire wearing slightly more in the center but by the time we switched them out the edges where worn quite a bit as well.

This was what 179 did on both of our robots after IRI. They seemed to work pretty good for us as well.
