I was told no with my older kuhnle because the hubs are attached to the disc brakes... They are a bit limited to strictly Kuhnle wheels. NOW, i dont know if you can go to Kuhnle and get pneumatics from them? I had asked a couple people around here (well known drivers used to many vehicles for many years) and they said i couldnt put pneumatics on mine because the way the darn wheels have the disc attached. I never explored it further. I've sold the carriage. Felt it was too heavy for my mare after her injury.
