I recently switched to the schwalbe indoor trainer tire from a schwalbe swift 32mm and am constantly getting pinch flats. The cool thing is zwift detected that my trainer was loose before I felt the slippage. Very neat. Switching back to my swifts.
Just make sure your tire is set to 100 PSI as well. Was it detecting it all the time with the trainer tire?
No Eric. It detected it once the other times I felt the slippage before.
I’ve got a 25mm tire on now. I usually go to 100. The 23mm trainer tire was always at 110.
