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?

4 things to check

1 tires- Carlisles are junk. Goodyear Marathons seem to be pretty good
2 camber- Slight negative camber is good (slight upward bend in axle)
3 toe- A little toe in is good. Toe out scrubbs inside of tires and may
cause wandering.
4 tracking- axle is perpendicular to direction of travel

You can measure or observe all of these conditions.

I'm thinking my wear pattern rules out 1 and 4. Both sides wore out
on the inside. But more importantly I have a 2" square tube axle so
how do I change 2 or 3 if that might be my problem? And I can't say
that I have been bothered by any wandering.
