Tiny wheel
So I've seen teams use 4" wheels usually, and in some cases 3.25" wheels, but what stops teams from using wheels as small as 2" or 2.5"? Just out of curiosity.
I would think tread wear and not being able to sit closer to the ground due to 2x1 geometry would be the main reasons. However, I feel like you could reduce gearbox weight a little bit by using smaller reduction ratios.
