How many wheel weights do you have?

My shop said for 35" tires, they work until all readings under 20 are acceptable.

I just got the truck back, and sure enough each wheel was off by a few ounces of weight. They re did them all, and the ride is smoother. Altho, I still get a very slight wobble in the steering wheel on the highway. I can only visually see it when I let go of the wheel at highway speeds. Once I hold the wheel I can't feel it. Maybe it's just the wide tires and crappy PA roads.

I want you to be happy so I hesitantly post this reply, but my steering wheel thankfully doesn't have any movement on the highway. Sounds like there is still something minor going on.

Im going to travel some diff highways in the coming weeks and see if it still does it. The one I travel on a daily basis is pretty bad.

Any thoughts on what else it could be?

Guess driveshafts being out of balance from the factory is very common on the F150forum. I may take mine to a local shop and have it tested as well.

Is the effect speed sensitive? If so, is it sensitive to road speed or does the effect change if you keep constant road speed and force a gear change? If it is sensitive only to road speed you may have a slightly bent/warped wheel. No amount of sophisticated balancing magic will smooth that out.

There are a ton of them on mine beadlock capable wheels. One has 19x .25 and then another has none. The other 2 have 10x .25 weights. Crazy!
I run ATX Slabs beadlocks and 37" BFG KM2 that have seen some rocks on my jeep. I mount them myself and slap them on the jeep. Never been balanced. Drives great. So is it the tires or the wheels that need the weights?

It is not speed sensitive. Per your advice, I held a speed of 70, while in 10, 9, 8, 7, & 6th. RPM ranged from 1600-4200, and had no affect on the vibration.

What's odd is the vibration starts around 45mph, and remains the same at 75mph. When i've had balanced tire issues, the vibration would increase along with speed.

Another thing I noticed with 600-700 pounds of additional weight in the bed seemed to almost fix the vibration in the wheel. Once I emptied the weight, the vibration came right back.

Bet you a beer you have a bent wheel.

I was told the road force would tell me If I had a bent wheel?

Just trying to think how the dealer can confirm

I have no knowledge about road force balancing, but I do know that you can check your wheels for being true yourself.

You will need to rig up a stylus that you can position next to the wheel (not tire) as you spin it with that corner of the truck jacked up. (My dad used to do this yearly, and that was a good 50 years ago. This is not rocket surgery.) The stylus needs to be positioned four times per wheel:
- Outside rim vertical deflection
- Outside rim side-to-side deflection
- Inside rim vertical deflection
- Inside rim side-to-side deflection
This is just a visual inspection aided by the fixed point provided by the stylus. A pencil resting on a concrete block will do fine.
