Sure. The manual will probably tell you to run them at 3.5. My tires say 7 max running, 15 max to seal bead, and the manual says 3.5. I had them at 7 and it was bounching around like hitting a ballon in the air, so I lowered them to 5 and it's much better. 3.5 would probably be fine, but I haven't been back out to test that pressure.
