Just picked up my new (used) Ditch Witch 410sx. Back tire went flat on the trip home - it was leaking air all around the rim bead. Anyway, got it repaired and the tire shop put 50 lbs of air in it (which is the max pressure stamped on the side of the tire). Just for grins I checked the other tires - they all have less than 20 lbs in them but "feel" just as hard as the 50 lb tire. I'm thinking that a softer tire will get better traction? Anyway, what tire pressure do you guys run on your 410s? Thanks, George Oh by the way anyone interested in buying the H400 trencher attachment before I list it on machinerytrader or ebay?
