I would suspect the Pros would use the correct tires for different scenario also. Tape adds weight in the worst place, in the rotating mass.(A bad thing for the pros) Is it not centrifugal force multiplying the tire weight that balloons tires? (not trapped air) They would look like over sized donuts not pizza cutters. What is the weight of air? About .075 Lbs a cubic foot depending on the density. How many cubic feet of air is in a badland tire? less than one. IMO. Around 36-39MPH is when mine start swelling.
