I've been running my LWB recumbent eBike at 100 PSI in the tires. After being out of town for a while I went for a ride and thought wow, the bike is riding much smoother, as in the road bumps and dips seemed less jarring. When I got home I checked the tire pressure and sure enough they were down to 40 PSI.
What pressure do you all ride on?
I can tell you that at 100 PSI I feel every road surface imperfection, I'm thinking I could back down on the pressure but I have no idea how low is too low.
