Update-Balanceing Trailer Tires with Dyna Beads

My educations continues.

A few days ago, I asked a stupid question about balancing trailer tires.

During the discussion, fellow forum member, Huntingdog (Many Thanks), educated me on 'hub-centric' (auto) versus 'lug-centric' (trailer) rims.

I had taken my boat trailer tires to a local shop for balancing, guy comes back says my wheels are badly bent. I now know that on a lug-centric trailer tire that the center (pilot) hole can be 'off-center' and only purpose is for the hub to stick thru.

I removed those big, honking weights, S-hook from bungy cord worked great.

Huntingdog provided some links and told me that lug-centric rim required an adapter plate to be balanced on todays machines, which is rare and finding a tire person to even admit such a thing exists is rarer.

During all this discussion, I discover Dyna-beads. Once, I'm satisfied that Dyna-beads are legit, I called and ordered some, paid extra to rush them as I was in a hurry.

Installation was super easy thru the valve stem, used my Sonic Care toothbrush for vibration, less than 3 min. per tire.

Went to our 1 source of free air, small town, air hose gone. Put 4 quarters in another place, airing up with wore-out chuck when it slips off and all kinds of******comes out of the air hose. This was on a Sunday.

On Monday, Called Tech support, Guy says 'if any compressor oil got inside the tire, the beads won't work'. So, after all of this, I'm going to start over. Do it right.

Called my Ford Dealer, service advisor told me that their air compressor had several water and oil filters/traps, come on in.

Break down the tires, and sure enough, one of the tires had the dyna-beads stuck to the inside, like 'fly-paper'. Good thing I caught this. Wash the insides out, twice, and a final wipe with alcohol just before remounting. After airing up, I waiting a few days before adding the beads, wanting to ensure no leaks.

At this time my Ford Techs was interested and wanted to see my process for getting the beads inside the tire. Friday, I went in, set up shop on my tailgate, had my little bottle, stem, and....my Sonic Care toothbrush....

Remember, this is the 3rd time, I have balanced this tires!!!

Ford Tech says, 'Wow, this is neat, I'm getting the Boss!!!'

Now the Service Manager is brand new at my Dealer and I had not met him yet. He comes over as I'm starting putting in the beads for the last tire. At to my suprise, he knows about 'hub' versus 'lug' centric wheels and he was familar with the Dyna-beads.

We talked for a while and I'm getting a 'good' feeling about this guy. During our talk, he said 'Fred, Why didn't you let us balance your tires, you have spent a lot of time and money on the Dyna-beads.' Bill, 'I would have but you do not have the proper adaptor plate.'

At this point Bill went over to the balancing machine and pulled it out. 'Here it is, looks like it has never been used, I saw it when I was checking things out'.:S:S:S

Hope you enjoyed,

Fred
  • Dyna Beads are thought by a lot of people who have tried them as snake oil. Especially motorcycle people who have had less than stellar luck with them. Personally I'd either use metal weights or leave them unbalanced. JMO of course.
  • I put Dyna Beads in my new 19.5" tires in Feb 08. Nitrogen to 90 psi and when I gave it to my son in 2011, I lowered a couple to balance them all out at 85 psi. I think it was 8 oz of beads for each 150 lb tire and wheel combo, but I have slept since then just not in a Holiday Express.

    My brake drums are out of balance by 5.5 oz. The tire/wheel assembly is out by 2 oz. Please explain how 3 oz. of beads will correct this balance, and at what speed.


    How are you using tire weights to balance your brake drums currently?

    As a practical matter if I was getting bad vibration at a corner and thought it was due to brake drums and I was using beads I would try rotating the wheel 180 degrees on the hub so that the out of balances counteract each other.

    At least until I could get the brake drums turned and balanced.

    I've always heard it called a Haweka. I find most good sized tire shops will have it but you have to ask for it because most modern rims don't require it (Land Rover steel rims do).

  • I got this one a couple of years ago.Air compressor

    I haven't had to use it much, but I am impressed with it.
    Very quiet, and fast. Other good things too. Will follow up later as work is calling.
  • OP replying to my own thread.

    Now that I have to use water and oil free air compressors (A little moisture is ok as the beads are ceramic, but I'm going to avoid if possible), I need a compressor.

    Since I don't have a working 12volt compressor and finding a suitable air source while traveling is a joke, I want to go ahead a get a decent 12v.

    I'm interested only in a quality unit that uses aligator clips directly to the battery. and can handle 80psi for my Michelin XPS Tractions:)
