Timing set.... 15 at idle (850), 26* at 1100, 28* at 3000 rpm, 36* at 6000, WOT - which is another setting is the same except 34* at 6000 and WOT ..... seems to work great now.... pictures at 11

12 oz. I have 38s (385/70/16). I was driving 80 mph on them yesterday. What is interesting (to me at least), the 38.5 bias plies are significantly lighter (read 20 lbs per tire) then the radials but use the same amount of balance weight.I'm having a hell of a time getting my beadlocks balanced. I was wondering how many bb's you put in each tire. I have 37" tires on 17 inch beadlocks. Let me know what you think, cause I am all out of ideas
Thanks, I had bad vibration at 48-53 mph, got them rebalanced and now 60-65mph is where they shake. I will start with 12 and see how it goes. Above 65 all the way to 95 I have a smooth ride. However most of my time is between 55-70 and that current speed has bad vibration right in the heart of the envelope12 oz. I have 38s (385/70/16). I was driving 80 mph on them yesterday.

I'm sure you've checked, but also be sure your wheels are straight - if a flange is bent or spindle, many troubles do occur. I never uploaded it, but I have a video of the tires spinning while the truck was on jackstands to verify this.
Otherwise, defective tires will never balance right - I used to work for an auto rental company, one of the ways they save money is refuse to balance the tires. If there is a vibration, we simply returned the tire (and never heard a peep from the manufacturers).
good luck
So I wanna say up front- I’ve never had any experience with beadlocks. How is the initial startup when start from a full stop? I ask because my wife drives the truck half the time in the summer and she doesn’t need hiccups. So is it seamless? Suitable for a summertime driver?12 oz. I have 38s (385/70/16).

I hope it fixes it.... in my experience, out-of-balance tires get progressively worse until it's undriveable....Thanks, I had bad vibration at 48-53 mph, got them rebalanced and now 60-65mph is where they shake.

If I understand your question... beadlocks only change how it drives indirectly - via increased weight and lower tire pressures. IIRC, max psi on these beadlocks is 28 psi, which is quite a bit lower than what most tires recommend for minimums. On a relatively light '40, lower tire pressure isn't really noticeable.So I wanna say up front- I’ve never had any experience with beadlocks. How is the initial startup when start from a full stop?

55-65 is where mine shake. Running 10 oz of air soft beads in each. I tend to drive above 65 on the highway to avoid it. I wonder if that is a good excise if I get pulled over?Thanks, I had bad vibration at 48-53 mph, got them rebalanced and now 60-65mph is where they shake. I will start with 12 and see how it goes.

Yes i meant BBs, Thanks for interpreting my question. My main concern is my wife going to have one more thing to compensate for and it sounds like not. I’d be surprised if I could hear the BBs rolling around with the top off.

I suspect that you meant BBs not beadlock, if not, the following words can be ignored.
As far as using BBs to balance the tire, if you know what BBs sound like rolling around, you'll notice the noise (but it is quite light). As far as dynamic balancing, basically they become a ring inside the tire - they try to go to the center of the wheel, then radiate into a ring. If there's a vibration, more bearings can congregate where the out-of-balance is occurring (ever play one of those rattle games where you need to move a bearing through a maze?) I suspect, though I haven't actually done the math, that the ounces of bearings required for a given tire size are just enough for a ring one bearing deep all the way around the tire... thus that ring shrinks to the area of inbalance... Speed really doesn't affect that happening because at 5 or so mph, there's enough centrifugal force to make the initial ring.
The other question I had, which I answered when I swapped tires... it doesn't affect the inside of the tire at all - you cannot tell that there were bearings rolling around inside.

The Air Soft beads are pretty quiet. I can't hear them except when I am spinning a tire when on jacks or when rolling a tire on the ground, like when rotating tires. Being plastic they do tend to disintegrate over time. Based on my driving experience I estimate they are good for 10k to 15k miles before needing to be replaced. Metal BB's have a better life span.The BB's should not really roll around at any speed. Once the tire starts spinning enough and the BB's gain enough inertia, centrifugal force should keep the BB's in a pretty fixed place until the tire slows down enough that the lack of inertia allows for the BB's to succumb to gravity.
I hear them, but they're not something you'd notice right awayYes i meant BBs, Thanks for interpreting my question. My main concern is my wife going to have one more thing to compensate for and it sounds like not. I’d be surprised if I could hear the BBs rolling around with the top off. Thanks
@srgould41, and others with tire wobble. I had a HORRIBLE time with a set of 37” radials on 17” bead locks. Used high quality glass beads to balance, no change. Checked wheels, spindles, bearings... finally swapped to new tires and the issue was gone. Figured 10 year old tires that had been wheeled hard was actually the root problem. 55-60mph on links was BAD55-65 is where mine shake. Running 10 oz of air soft beads in each.

36" swampers aren't the best for street driving for sure.@srgould41, and others with tire wobble. I had a HORRIBLE time with a set of 37” radials on 17” bead locks.

I have videos as well, but they'll take some editing....I would add my pictures, but yours were better. Great day in the snow. Maybe we'll get another good snowfall and we can go again.
