Just curious if anyone out there is running custom floater tires on their Nitro sprayer. 650's are the biggest factory option, but there is a company that will make any wheel size you want. I've heard from the dealer that some Nitro owners have tried 710 Trelleborg or Michellin tires. I've sent an email to the factory to see what is the max tire size they have tried and how the testing went, but no response yet. I realize that this would void the wheel motor/torque hub warranty and I don't care, need as much floatation as possible.
