The trailer does not wear out faster, the tires wear out faster due to the axles being on different turning radias' the tires scrub through the turns. Which means the tires are dragged sideways as the trailer turns. And by turns is every time the trailer is not going in a straight line such as a curve on a road.

what makes you say that?
No you can not see, here, feel the tires being dragged sideways. It is an imperceptible amount to the senses. But not to the forces of friction which there is no escape from and that is why the tires will wear out faster.
This drag is set up due the tires on the front trailer axle and the rear trailer axle have different turning radius' due the distance of the axles from the pivot point of the trailer.
This difference in turning axis' causes the front trailer axle tires to rotate at a different speed then the tires on the rear trailer axle.
Do not confuse this difference in tire revolution speed of the tires between the tires on each end of the same axle. The job of the rear differential allows the tires on opposite sides of the same axle to revolve at different speeds.
Which eliminates those tires from scrubbing amongst other things.
Trailer axles whether single, double, or triple do not have differentials. And do not need differentials due to the fact that trailer axles are classified as dead axles. The axles do not turn. The wheels on each side of the are free to rotate at different speeds. So with single axle wheels there is no scrubbing of the tires.
However being when multiple axles are used all the axles on the inside of the turn all trying to rotate at different speeds as so is the case with all the tires on the outside of the axles on the turns. So the tires will scrub and wear faster. When a tire is going slower then the other wheel the trailer forces wheel to try and turn faster. When the wheel can't turn fast enough it gets dragged through the turn to make it cover that same distance as the wheel on the adjacent axle. The dragging of the wheel is called scrubbing.
This dragging/scrubbing is what causes the tires to wear faster.
There are fed laws and state laws. Trailers that weigh 1,000 lbs have to have brakes in my state. I said weigh 1,000lbs. I did not say any thing about how much a trailer can carry.
A trailer that can carry more weight has to cost more. More materials. Stronger materials. More axles.
Get more has to cost more. More is not always better. The QEII maybe the best ocean liner but it would suck to use it to go for trout or bass.
I'll let you figure out which trailer needs power, which means more fuel has to be used to pull it. A heavy trailer or a light trailer.
If you have 2,000lbs of equipment why do you need a trailer that can carry 7,000lbs?
