Trailer Tires??

I have a dual axel trailer and had new tires put on in July. I looked at my tires the other day and the back tires are wearing much faster than the front tires. It is to the point where the back right rear tire almost needs to be replaced again, and the front looks new. Is my trailer jacked or could it be a bad tire? If anything I would have thought the front would wear faster because when on my truck the trailer is tilted down very slightly.

Most likely your trailer is a little bent, it can happen if you catch a cross memeber at the launch. does the trailer look a little sideways when it goes down the street?

A trailer shop should be able to do a wheel alignment for you and fix your problem. Some alignment shops can do it too.

Rotate your tires. With a tandem axle trailer, when you make a turn, you will always have a pivot axle and a skidding axle. The tires on the axle that skids will always wear out faster, so rotating them will give you more even tread wear and longer tread life. just my $.02

If you are making sharp turns on concrete the axles will shift/bend. I used to have my trailer lined up every year they actually heated up the axle and straightened it. Now I have just been rotating my tires a couple times a summer and also flipping the tire on the wheel (I have access to a tire machine). Hold a straight edge against both wheels on the same side to see how far out it is, should touch the tire in four places.

Another way to see if your tires are on the same straight path is to just roll through a puddle...cheap and efficient!
