annoying bouncy ride pulling trailer

one thing that trailers lack are shocks. and any suspension comes from some leaf springs. leaf springs being more rigid and when trailer is empty. basically causes trailer to jump up and down. when a tire on trailer hits a bump. vs the springs giving some allowing tires to roll over the bump.

once you get weight on the trailer. and in that weight on the springs. so when tires on trailer do go over bumps. the leaf springs actually "flex" causing the trailer tires to never come off the road but rather just roll over the bump. and folks generally experience much better ride once weight is placed on the trailer.

================
the current double axle trailer i have now, the wheels are almost centered between front and back of trailer. and for me, it seems to help if i raise the ball hitch/receiver up a couple inches to bring front tires on trailer up off the ground just barely. gives smooth ride when empty. doing this causes more tongue weight. and more weight to be placed on rear axle / leaf springs / tires. allowing the leaf springs to "flex" keeping trailer tires on the ground. vs trailer jumping off the ground when tires hit a bump.

on trailers where, trailer tires are further back on the trailer vs more near center, you might try dropping the ball hitch / receiver. so trailer front end is lower than rear. to bring the rear tires off the ground just barely or take weight off of rear tires some for a smoother ride when trailer is empty.

other words to above 2 paragraphs, it would be like turning a double axle trailer into a single axle trailer. by adjusting the ball hitch / receiver height to change tilt angle of the trailer.

=========================
since i have added a locked tool box to front of trailer. the extra 100lbs of weight has caused trailer to run extra smoother. without any adjustments to ball hitch / receiver empty or loaded up. that 100lbs changed difference between being in a vibrating chair, to seating down and just sinking into a cushy chair.

with above, you might want to think about ramps you use, and were you store the ramps. adding extra weight on rear of trailer to hold ramps = less tongue weight. perhaps going with a lighter made ramps, or moving axles on trailer further back on trailer to allow more tongue weight when trailer is empty / very light load on it. perhaps just welding / bolting on some weights to front of trailer.

X2 on checking out the tires for out of round or tread separation.

I recently bought a new 18ft car hauler trailer and it shakes the truck at any speed. Like the truck and trailer aren't synchronized? Same thing when it is empty or with a 1200 lb bush hog loaded on it centered over the axles. What can cause this? I am pulling it with a 1/2 ton short wheel base truck. Thanks for your help.

Get the tires and wheels balanced. I am in the trailer business and see this all the time. When they balance them have them check the wheels for true. I have found about a half dozen new trailer wheels that look brand new which are bent.

Anyone who says trailer tires dont need balanced is a idiot.

Have the tires balanced. And make sure trailer is level with truck.

There are two schools of thought on balancing trailer tires...some for, some saying it aint necessary.

Just as important however, is making sure that the tires are inflated sufficiently. And, you can't tell by just looking at them, or even kicking them sometimes. Many times an under-inflated tire (on a tandem axle trailer) will not show until you get a significant load on the trailer (much more than 1200#). When my empty trailers shake my truck, I immediately check the tire pressure. That has always been the culprit in my case, for both my tandem axle trailer with duals and my tandem axle trailers with single wheels.

If the trailer was sitting for a long time, the tires could have developed flat spots too.

I'll tell my tire guy that you said he's an idiot. :p :laughing:

I use a really popular local tire shop. It's one of the biggest I've ever seen. They said I was the first person who had ever asked them to balance trailer tires.

I am telling you it makes a difference. Think about it, its a 40# spinning disk and then once you have it done you will be amazed at how much weight it takes to balance them. On average trailer tires and wheels are of lower quality than auto stuff.

I agree that it makes a difference. But similiar to Misfire, when I asked the tech at the tire shop to balance the tires on my trailer, I got funny looks.

Yeah not balancing trailer tires makes no sense. They are rotational mass... balanced rotational mass will not vibrate. Period.
