A:AnswerShould be able too yes. Just match it to what's on the original tire which I believe is 10"×2.125"
Solid rubber will be slightly smaller and tubeless should be about same size
A:AnswerSadly it is not. Though might be able to find and aftermarket one online though you would have to disconnect and reconnect everything to put one on
A:AnswerNot bad. On high gear it holds a steady 12-13mi speed for me going up hills and I weigh roughly 220-230lb.
Would roughly depend on your weight, weight carrying, and wind really
A:AnswerIt can handle light to medium rain but wouldn't rec puddles deeper than inch and will need to clean break disc after each ride as once dried will cause some issues
