3 part wheel poll

1:what diameter tires are you using?
2:what type are they? (pneumatic solid etc…)
3:how much ground clearance do you have?

i dont know how to make a 3 part poll so ill just do tire size

i found out how to make multiple choices available, so select tire size then select type

omni wheels, unless i am mistaken, I dont see any choice for them above.

what about treads?
