Liquid tire balancing again

After running a vibration analysis on my Jeep and finding the tires to be the culprit I decided to try to balance them. My bubble balancer showed they were not too bad so I was sure the trouble was dynamic balance.

Getting the tires dynamically balanced at a local shop costs over $50 so I wanted to find a way to do this myself. I have experimented with liquid balancing in the past with reasonably good results. So I decided to give it a try on these stubborn BFGs.

I first removed all the lead weights. I then removed the valve cores to let all the air out. I then broke the bead on one side to make a place to put in the liquid.

I used some used antifreeze that I had handy. I weighed the heaviest of the four wheel weights and put about that much liquid in each tire. I just poured it between the rim and the tire bead.

I reseated the beads and inflated the tires back to 30 psi. I then put then back on the Jeep and returned the nicely balanced smooth running Goodyears to their owner.

The first test drive showed that the shimmy at 55 was mostly gone. It is so slight as to be able to completely ignore it.

I took it to the interstate and did a quick speed run. I could only hit 70 due to traffic but I was happy to note the mirror shake was gone. The ride was not as smooth as the Goodyears but it is certainly acceptable. I will have to try again later to see how it runs at higher speed.
