dyna beads

Postby donhiatt » Fri Mar 01, 2013 10:43 am



I am putting a new 130/70 r18 shinko se890 on my front tire of my 89 goldwing trike and am installing dyna beads..I have been told they will stop the cupping.I had a bias tire on the front and it cupped in about 1000 miles --boo
Does am one have history on the beads using a radial tire??

Well I've been using them in my truck now for over a year, and they are working great - no vibration, excellent wear. And it has radial tires, obviously.

There is no limitation given by the company for using it only on bias ply tires, I expect you'll be quite happy with them.

I cannot state whether or not the dyna beads will stop cupping, but they sure make the balance of the tires nice and smooth. 10K miles and no cupping on a set of Avon Cobra front and back, and they still look good. These are the first tires that I have put the beads in, and I like them.

I don't remember what I put in my truck, I made a guess - I think around 12 oz per tire? Whatever the amount was, it wasn't enough, I ended up ordering and installing another 4 oz per tire, and that did the trick. It's been great ever since.

Same thing here, running the same tyres on my GL1800 and have seen a similar mileages without any cupping and no vibration.. I am very happy with them. I also installed them in my truck and am also very happy with them. I can't see why a bias belted tyre would make any difference to their ability to balance the tyre, not sure about the cupping? You might try running a slightly higher tyre pressure and see if that helps with the cupping.

Here is a link that has tire charts for a bunch of different tire sizes. Tells you how much for each size tire.

It doesn't hurt to use too much, but not enough will cause an imbalance. You might not need much if your tires are already close to being balanced, but if the tires are starting out imbalanced, you'll need more to counteract the imbalance. It all depends on how well the tire was balanced when it came out of the mold.

]Yesterday afternoon, I put 2 ounces of Dyna beads in my new front tire, took it for a short ride, had no wobble at all. I really felt I made a wise decision to install them. However, this morning, after a below freezing night, I left my house, went I would say the 1st quarter of a mile, and developed a wobble that almost threw me off my bike. I was going about 30-35 because it was cold and I had all I could do to keep from crashing. I was really scared. I've been riding for over 45 years and never ever had this occur. I managed to slow down, with the wobble still there until I just about stopped. Got off the Goldwing, checked all bolts on the forks and everything appeared to be normal. Started off again, it felt like a perfectly balanced tire and no issues for the rest of the day. My conclusion? I believe moisture inside the tire caused the Dyna beads to freeze to one point on the tire and let loose as I slowed to a stop. I can't emphasize enough how dangerous and instantaneous that wobble was. So, if you're using them, they've had a chance to freeze time/temp wise, and it's cold out, I suggest kicking around the tire to loosen them up and go real slow at first to make sure you don't experience what I went through.

If you have that much moisture in the tire you need to demount it and start over with a dry tire. If the moisture is still in there it will do it again, as it will clump up again.

It wasnt the dyna beeds that caused the wobble it was moisture from the compressor you used to inflate the tires. You need to demount and start all over again. If you dont you will have this problem again and again, next time you may not be so lucky. 8-)
Ride safe, Todd

Correct, and next time make sure you fill your tires with a compressor that has an air drier (dessicant) on it.

I currently have dyna beads in my tires. but, I plan to remove them come warm weather and install this product.

Ride-on not only balances the tire but works as a sealant as well without damaging wheels the way Slime will.

Just be aware that many shops will either refuse to change your tire, or will charge extra, as the liquid sealant makes a huge mess on the tire changing machines when the tire is demounted.

Yes they will and I can't really blame the shops either. But, it is my understanding that Run-up does not make a mess like Slime does. Watch the video, I think it addresses the mess concerns.

Re: dyna beads UPDATE

Postby Senkoguy1 » Wed Apr 02, 2014 8:32 pm

I got a call today from Dyna Beads and as I suspected, there is a lot of moisture in my tire that is causing the clumping/freezing issue. What I had done was take my air tank to a gas station, filled it, and used that air to fill my tire. Apparently I used an air machine that did not have a dryer filter so Dyna Bead's recommendation is to remove the tire, wipe it really dry, then have Nitrogen pumped into the tire.

Now, I've ridden the bike for a couple of days now as the freezing temps here in New York are pretty much done with, and I haven't experienced the wobble at all. I still feel I made a good decision in using these beads because I no longer have that slight "wobble" Goldwings are known for. Not that I do it, but I can let go of the bars when slowing down, no wobble at all. I am recommending Dyna beads to people I know but I'm hoping their instructions for installation include the need to put in "dry" air so no one goes through the harrowing experience I had.

When mounting the tire make sure you use very little liquid around the rim. That liquid can have the same affect on the beads also. Your compressor may have been dry but when tire was mounted it could have been excessive liquid around the rim.

I have been getting about 9,000 more miles on my tires when using the dyna beads. No cupping on them.

I also went to using the beads in my cars, truck, and even my motorcycle trailer tires.
car and truck valve stems have a flap of rubber on them- so I use a drill and drill out that piece of rubber to install beads through the valve stem.

Thank you for putting this out there. I was looking into putting them into my '81 GL1100, and I wouldn't have known to look for moisture or using a compressor with an air dryer. Now I know!

Tire installers commonly use a sticky, goopy tire lubricant to allow the tire bead to seat on the rim. If this is slathered on the inside of the rim or tire, the beads can and will stick to it, and won't work properly. They should know to use an alternative lubricant, or use it very sparingly, and only on parts of the rim and bead that will have it "scraped" clean of lube when the bead seats.
