For my Ural side car rig I have used Duro's, and I recently bought Heidenau's that I have to mount for next season. The Duro's have been okay, whereas I thought I'd try something different.  When I was last in motorcycle school (2019) the instructors and manufacturer reps said to never use an auto tire on a motorcycle wheel.  The shop wherein I was pulling wrenches in 2020, its owner had me 3x mount auto tires on customers  motorcycles, because he has used them himself on his own  motorcycles.  They required a lot of PSI to get the bead to set. I personally if I had my own shop would never recommend to a customer. And I would never use an auto tire on any of my motorcycle wheels.
