Drive axle weight question

[nightmoves]

I recently returned from a 1600 mile trip with my 26' enclosed car carrier with a 4700 lb vehicle.I have the Reece equalizer setup and is adjusted to all the right heights and specs.It pull's fine and does not "wiggle" but it gives you an uneasy feeling when being passed.Not just semi's but small vehicles also.
Here are the numbers;
Truck is an 06' F-250 4x4 Longbed 10k gvw on factory LT 275/65 20 tires.Steer axle is 4860lbs and drive is 3300 lbs.
Loaded w/ trailer: steer is 4760 lbs drive 4280 lbs and trailer is 8460 lbs.Do I have enough weight on the drive?
Thanks.

You basically have 980lbs of tongue weight.
What rating bars do you have?
All of your numbers look pretty close.
You could try and adjust to give you more tongue weight, that might help a bit.
What tire pressure do you have in the trailer tires and also the rear truck tires?

12k rating on the bars.I only have one link hanging on the chain.
Triler tires are at 65psi max load range c.Truck I have 80 front and 70 rear.I guess I could try moving the loaded vehicle more forward for more tongue weight.Thank's.

According to the weights listed, your loaded trailer is 9340#, you need to have at least 1200# on the hitch (12-15%) without the equalizer bars installed. I'd try lowering the tire pressure too, there's no need to run over 60PSI in the fronts, the rears should be adjusted according to the axle weight.

Formula: W / 6830 X 80 = PSI

W=actual axle weight
6830=maximum tire capacity
80=maximum cold PSI

I usually round up to the next 5PSI mark.

After you get the trailer loaded correctly you can adjust the equalizer bars to level things out.

I agree with the tire pressure. You are running way to much in the front of your truck.

Are you pulling the car in forwards or backing it in?
I would make sure the motor is towards the front of the trailer.

880 lbs of tongue weight on a trialer that weighs 9340. That is less than 10% tongue weight. You want more tongue weight on that setup. put another 300-400 lbs. on it and you will notice some difference. tag trailers are always going to feel a little weird. It is their nature to pull crappy. I would reverse the psi on your tires. Run the rears 75-78 and the fronts 68-75. It will not hurt your rolling resistance (fuel economy) to pump the tires up

Thanks for the advice.I pull the vehicle in.I will try bringing it more forward one foot at a time and measure the tongue weight,also will adjust the tire pressure.
