My last set of tires wore away completely on the insides long before
the rest of the tread was gone. I was talking to one of my buddies
and he had the same problem. I'm thinking the axle develops a bow in
it. So earlier this spring I left the floor jack under the middle of
it with it jacked up some. Too early to tell if the new tires are
wearing the same or not. Can't measure the distance between them at
the top and bottom cause the street and the boat are in the way so I
don't know if the camber is ok now or not. Anyone else have this
problem and do any investigating?


your on the right track, but it might be time for a new axel.
