Well here's another strange one, I put new tires on a 14' Sled Bed with cap and got about 3500 miles on them so far, two years old. Greased bearings this fall and noticed they now have all the symtoms of under inflated tires. There is no slop in the wheel/bearing. They are now feathered and very wore, uneven, and halfway down on the outside and inside but the middle is like new. These are load range E, which is what the original tires were, same size too. Trailer spec is 50 lbs per tire. So after sitting a year over the summer they still had 46/47 lbs. Would a couple pounds low do this? Both sides are like this. Bad tires? Wrong air spec for the replacement tire? I have always gone by the spec on side of trailer - 50 at start of trips. Any ideas? Axl not aligned?
