Roger Lee Posted June 17, 2021 Report Share Posted June 17, 2021 Many of us use 35 psi. The reason is when we first used those tires back in 2007 we used 29 psi. The problem was they looked out of round. So Desser sent us another one. Same thing happened it looked out of round. Called Desser and they ask what pressure we were using and told them 29 psi and they said that wasn't enough pressure for 8 plys to keep their shape. The other issue was that during taxi the tire would rotate on the wheel which would have lead to the tube stem being pulled out which I've seen about a dozen times. Desser wanted far more pressure than 35, but that works just fine. The other problem is the original marc Engegno front wheel is terrible for good friction stability on the rim and tire bead. Matco's are far better in preventing tire rotation with lower pressures. The other issue with 29 psi is owners don't check tire pressure often enough and then it drops a few pounds and the tire pulls the stem. If I'm not mistaken FD did their certification drop test at 35 psi and many of us have been using 35 psi since 2007 without any issues..
