I am 235 lbs. and run my 23mm tires at 120-140 psi on a concrete velodrome. On the road I run my 28mm clincher tires at 80-90 psi. You can go with much less psi than you are currently using. A lot of it is experimenting on what works for you. I don’t like that squirmy feel, so I ride with a little more pressure. Make haste slowly when lowering pressure and stop when bumps cause the rim to impact the obstacle.
