[Rhodes22-list] Trailer Question

[Bob Keller]

Hi All,
I am finally realizing that my trailer tires are wearing only on the inside, but look almost new elsewhere.  I just returned from a trip to S. Florida which I do a couple times a year and this is ~1,000 miles round trip.  I am reading that this could be caused by everything from the tires being out of alignment to the axle being bowed because it is insufficient for the load.  The trailer is a Triad single axle and is exactly four years old.  Any ideas as to what would cause this?  I can't believe that I need a new axle after only 4 years?
 
Thanks,
Bob K
