Should Trailer Axle Be Bowed Down in Middle


trailer tires wearing out. Hi I have a boat trailer and the axle is a little bowed downwards in the middle. Would this cause both tires to wear on the outside and inside.


Helpful Expert Reply:

A trailer axle should actually be bowed upwards in the middle and not downwards. When the trailer is loaded with your boat, that upward bow will flatten out and your tires will make even contact with the ground.

The downward bow of your axle should not be happening so you should be sure you aren't overloading your axle. I recommend replacing your axle and ensuring you stay under the axle capacity. You can also eliminate the issue of axle bow by using a Timbren Axle-Less Suspension like part # A35RS545.

The Timbren axle-less suspension systems are simply bolted or welded so you do not have to worry about finding an axle that meets any specific measurements. They also offer you an improved ride compared to a traditional through-axle because the Timbrens work independently so if there is a bump on one side of the road it won't rattle your entire trailer; this is also true because the Timbrens have progressive springs that absorb shock better than a traditional axle with leaf springs.

I have added a link to a video review of this suspension for you to check out as well as a link to our selection of Timbren Axle-Less systems.
