Question:

I am building a 30foot boat trailer. I am using 6x6x.25 tubing and have bought 3 set of 3500# timber axles from you, so I should have a total gross weight capacity fo 10500 lbs. How can I calculate where I can place the axles and how far apart from each other can i place them. Any Help would be great

Expert Reply:

Let me start by saying that the Timbren Axle-Less Suspension System # A35RS545E you purchased is not for triple axle trailers. I would just suggest making your trailer a tandem axle and going with either the Timbren Silent Ride Suspension for Tandem Axle Trailers 14,000 pound # TSR14KT01, or 10,000 pound # TSR10KT02. You will still need 3 inch axles to fit your trailer's frame.

I've attached a picture that can help you determine where to place your axles. You basically want to locate them so that the tongue weight is 10 percent of the trailer's total weight. A good starting point is for the second axle to be approximately 60 percent of the way from the front and then adjust from there.
