I hope all the teams that bought up the stock of pneumatic wheels are testing. It's been many years since we've considered using such large tires and some of us might be a bit rusty with our calculations
Maybe convert to chain and get some added ratio by using larger sprockets on the larger tires?

I love chain*. Haven't converted to this new fangled belt stuff...

*chain let's be be wrong late and recover. I can laser cut new ABS sprockets an afternoon and make up new chain lengths and I'm off an running with a new iteration. Belts make me order new pulleys, new belts, ... I just don't see the benefit for most FIRST applications.
