Re: Should I get my tires balanced on my boat trailer?
If you don't balance the wheels/tires, try towing the trailer and see/feel what it is like.
I had gotten a new trailer and when I got on the highway, my entire truck was shaking and the trailer was about bouncing up and down on the road. I promptly stopped at the first tire shop and they balanced all 4 wheels and the problem was solved.
As my tires started to wear, I noticed one of my fenders on the trailer shaking during a certain speed. New tires and a balancing and everything was smooth again.
No doubt that balancing has to be done. Most of the vibration gets masked from the boat/trailer suspension and its isolation from the tow vehicle but imagine what the imbalance must do to the bearings et-al.
