Here some more info on my situation.
I filled the tires to 40 psi and let sit in the sun for a few hours to get a nice "tan" and warm up. Later that day I re-balanced the best of the bunch to confirm the weights. 2.5 oz on the inner and 3.5 on the outer and 22 lbs of road force. I broke the bead and put in 6 oz of Counteract beads (I bought 6 oz bags). Refilled to 40 psi and spun on the balancer. What I can say for sure is the balancer does not like these beads. It is pretty much like spin of the roulette wheel for results. Every time is different and can be very different. Road force is the same, which I kinda figured. The balancer was even starting to throw a "wheel slippage" message at times. My thinking is the randomness of the beads and depending on when the snapshot of the balancer is taken, yield varied results. I guess the only way to know is to install and drive.

Before I do that, I am working with the distributor to see how they want to handle. I am not putting on the road until they say so.

To give some perspective, here are some videos of the tire on the machine. If that redwall is supposed to be true all the way around, this tire (the best one of 5) is a way out of whack. You can hear the high spot as it goes around.

Dude that tire is HORRIBLE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ....nothing, repeat NOTHING is going to balance that!


I'd send these vids to the mfg/distributor and either get another set, or refund IMHO

And that was the best one.
Wondering if the weight of the car + some heat from driving would massage back in shape? Other option i looked into is tire shaving, but then if the tire does change shape in future, the shave is erased.
Hoping they come through. I did buy them last fall (they were produced in September) and only got to install now due to all my delays.

as dayclona said, those tires are [to be Very kind] NOT round.
however, that tire is no worse than they were back in the day. i always wondered about that because some tires like that balanced to where you couldn't feel them, and others would hop all over the place.
and if you think those are bad, you should have seen some of the ReCaps that were done at the same shop i worked at. [those ReCaps had the reputation of being the BEST in the area ! go figure.]

So here is the update. I was going back and forth with the tire company and they were saying that road force on a bias ply is not the way to go. They would send me new tires if the spin balance weights were excessive and I could not get to balance. By turning the rim I was finally able to get all the tires to balance with a 2 to 3 oz of weight max. Road forces were still all over the place from 20 to 70 lbs. Rather than deal with another set that could be poor I gambled and decided to just install. I did put in 6 oz of counteract balancing beads, but did not put any weights on the rims.

Last night I installed on the car, putting the worst road force tires in the rear. My car is only eyeball aligned at this point, so that still needs to be done. I will say I am surprised how smooth it was. I really did not feel anything crazy with imbalance over any other old mopar I own. Not like we have the greatest roads in NJ to start with. The more I drove the better it got. Given my lack of alignment, did not want to drive too long, but I did some runs up to 70 mph and cruised on some smooth roads. Felt pretty darn nice. Vehicle steers easier at low speeds, compared to the radials, which is nice with the manual box. These tires seem to hook up pretty well too.

I am really happy with the stance and look of these tires. Exactly what I was hoping for. Now I need an alignment and to install my simulated mags, which I have been keeping my NOS set cocooned up for several years. This will complete the look.

BTW, this is the first time I ever took this car on the road more than just puttering around the block. First tank of gas and for sure the first series of hole shots ever. Gave me goosebumps thinking back to when I was a little kid in 1980 sitting behind the wheel of this same car playing “Dukes of Hazzard” with my friends. I really have been waiting a long time for this car to be on the road.

Car looks striking and mean with those red lines. Reminds me of wearing the right pair of Pro-Kids 69'ners back then.

Enjoy the car and roads as long as you can.

I was pretty surprised how well the car handled and rode with the redlines. I going to do the road portion of dragweek on my f70-14’s

Congratulations, that is a super sweet ride with a great back ground.
Enjoy it while you can
Reminds me of beating on my '68 Coronete 500 in the 80's.
IT came from Arizona and was so mint for that type car in that decade.
383 auto with the console.
Man what a blast.
Still have it, but it's rusted so bad it will never get fixed.
My grand kids will have to gt rid of it, just way too many memories.

So the balancing beads seem to work? How did you judge how much to put in each tire?

So far, yes they work. If it ever stops raining more then a day here, I will finally get my car aligned and get to drive it more to tell for sure. Initial indications were that I did not notice any vibrations at all that I would deem an imbalance. Keep in mind I did get the tire to a position that really only had 2 to maybe 3.25oz of weight needed to balance. If I just threw in the beads without checking and trying to do some force matching of the rim and tire, results may not have been as good.

The Counteract site had a calculator that said 4oz. In the posts above someone mentioned 6oz worked for him. Given all the road force I was seeing, I erred on the side of caution and just put in 6oz. 4 pack was like $40 on Amazon.

I talked to Dynabead about balancing and they said not to put them in before machine balancing, that it would throw the balancer off and get readings all over the place, like you experienced. They say 65 series and below tires need them in addition to machine balancing.

are you guys saying the tire/rim combination needs spin or road force balancing PLUS the beads ?

In most situations I bet the balancing beads work right out of the bag and no further checking is needed and this what their calculators are built for.

In certain situations, like with my tires, if I did not do some level of road force matching/rim spinning, I am not sure the beads would have been enough. When I first installed, I was getting anywhere from 12-20 oz of weight. I was able to trim that down by spinning on the rim and force matching.

I feel that if you are getting the tires mounted, putting them on a balancer after to at least get a ballpark reading for spin balance and ideally road force, would be worth it. If reasonable for the balancing beads to work, throw the tire back on the mounter and break the top/outer bead. Pour in your balancing beads, air up, and be done. A lot easier to dump into the tire, then feed through the valve stem.

Hope to drive my car more soon, so I can further evaluate.

They say for 65 series and below tires. Go, read what their website says.

i have been experimenting with beads [of different manufacturers] for a little while, and using the recommended amount, some tires are perfect, some still have a little vibration. i haven't tried spinning them first, and there is no one around here with a road force machine.
more experimentation is in the works. i'm guessing too many beads will increase vibration by a bunch ? i'll try an ounce or two at a time and see what the results are.

Finally had the sun come out for a couple of hours and the roads dried enough to venture out. First mile at low speed I felt a shimmy in the steering wheel and I was concerned. But after jumping on a 55 mph road it smoothed out. After that, all was smooth as silk. I still need my alignment, but it rides pretty darn nice. I could notice no vibration after the initial mile.

as the beads will settle to the bottom when stopped, maybe that is what you felt ? see if that happens the next time out.
