Going for wider set of tires is what I had in mind. Money's a bit tight right now but I had a plan to convert to either:
- a 650B tubeless wheelset with Grand Bois Hetre 42mm tubeless (apparantly you can run Grand Bois Hetres tubeless)
- a 26" tubeless MTB wheelset with schwalbe super motos 26"x2.35 tubeless
- a 29" tubeless MTB wheelset with schwalbe super motos 29"x2.35 tubeless
I'm still a bit undecided as to what it's going to be.
I don't have any experience with tubeless wheelsets or tubeless tires, but apparantly you can run lower pressures with less rolling resistance and good puncture resistance.
