I know wide tires look cool and all, but these look wide enough that bump steer (deflection when running over an object narrower than the tire, offset from the centerline)might be problematic. Also issues with camber-thrust steering, so I 'd guess these are not at all like the single-track vehicles (bicycle, scooter, motorcycle) that we're used to. I've ridden motorcycles with super-wide flat profile rear tires and they were... spooky.
