So I just lifted my truck and put on steel rims that I sand blasted and painted black. Had my uncle mount and balance the wheels and they balanced just fine. Note the tires were used on my dads full size 74 and do not have 500 miles on them. Took it on the road and then vibrations. So went back to his house and we balanced them again. They were balanced using a cone in the hub hole in the rim. Drove it again and more vibrations. I maked the tires before I came home from work today and got on it a few times(1-2 shift is quite firm) and the tires did not spin on the rim.

Any ideas? Should they be lug-centric balanced?
My next step would be to have them balanced on a road force balancer.

 

Have you considered having a bent wheel perhaps? I know you said they are fairly new, but wilder things have happened.

I they should be hub-centric balanced if im not mistaken.

 

I dont think its bent, I took all the rims and spun them on the tire balancer and the most movement i saw at 1/8 of an inch on one of the rims.

 

Lets see, you modifyed your suspension now you have probs. Id guess if you put back the stock rims your problems would cease. Because the new rims are not hub centered

 

Don't you mean stock suspension? As for the rims I check and they are hub centric rims, they came off a 4x4 s10.

I am going to bet the tires have flat spots from sitting 6+months and not moving so I am going to drive it some and then balance it again and see if they are better.

 

Try spin ballance. Bubble ballance doesnt account for wobble or out of plane ballance. I'v never heard of a flat spot from setting dismounted.
Do you have a bent axle?
How did you get your shifts so firm?

 

They were on rims under my dads 74 full size sitting. I would say axles are fine, as no vibration with stock rims and winter tires on them.

 

Again we go you modifyed your suspension now you have probs. You un modify and the probs will go away. Hmm.
