    Most years, wheel size is about desired speed/torque tradeoffs. Since wheel size is, of course, related to the across-the-ground speed, like motor/gearing choices, it depends on your design goals.

    This year there is the added issue that you probably want to be able to climb and cross an on-field obstacle (depending on your robot design; goes without saying, but I said it.) Larger wheels make it easier to climb.

    Testing your choices is the best way to determine it. I haven't personally seen anyone use the 2.75 omni wheels this year. I've seen both 4 inch and 3.25 in testing. I liked the performance of the 4 inch wheels better, but I'm not building a robot. Well, not a robot for this competition.

    What he said. In the beginning of the season, the team builds multiple chassis and tries out various combinations of wheels in order to decide for themselves what the best solution for the year's challenge is. Driving is believing!

    we are using omni's on our bot this year, we decided to do dualies on the back to get over objects, so far it has proven to work

    generally, most teams use omnis as the standard choice, as they work well and defense isnt really a huge deal in the US

    It depends on what gear ratio you have for your base motors, but i would suggest 4 inch with speed internals.
