Well, my first thought was rather flippant--just stay off that trail. I just think this because 32c tires should be fine for most riding. 40c tires will be a bit better, but they will also
slow you down a bit as well. Not sure much would be gained by swapping out the 32's for the 40's.

Seriously, the trail seems to be the real problem. It needs maintenance. In the past I have contacted the government agencies that maintain the local trails in my area. Often
they are responsive. Often they are not aware that the trail is in need of repair. So, I would stay with the 32's at 80psi, and ride elsewhere until the trail is in better shape.
