• Why are 20 x 2.5 tires also called 19” tires?                  

        A. When trials biking was first starting they stipulated that the rear tire must be 20” in diameter. The bike riders wanted tires with more cushioning for their rear wheel so Monty took a 1” smaller old scooter rim and tire (which is nominally 20" in diameter) and used that instead of the standard 20" tire.  To help differentiate between the two tire sizes the non-standard small rim tires are called 19".
