Tire wear

[Becky Burt]

I have a 2001 Stratos tandem axel trailer and boat. My tires are wearing wierd. One (left back) is wearing on the outside edge but all the rest are wearing on the inside edge. I bought it used a few years ago and noticed some wear then. I generaly dont make long trips with it. I need to replace my tires now but was wondering what would cause them to wear that way. If it is a balance thing no big deal but if the spindle has something wrong I need to get it fixed. Any ideas on what it could be?

Thanks, Becky

Sounds like the axle has shifted forward on the right side or back on the left causing it to toe towards the left. Look under the frame and see if it looks like the axle on either side has shifted slightly.

Is the wear excelerating? Also is the tongue straight?

Uneven Tire Wear ?
Center Rib Wear = Over Inflation
Outer Edge Wear = Under Inflation, High Speed Cornering, Positive or Negative Camber
Camber or Toe Wear = Misaligned, Loose Parts, Incorrect Ride Height
Diagonal Wear = Incorrect Rear Toe Adjustment
Cupped Wear = Loose or Worn Parts, Improper Wheel Balance.

The trailer does not have axels that go from one side to the other. I guese it is called a spindle? I supose I just need to take it in and get it looked at for a diagnosis.
