High speed vibrations with Dyna Beads

[ttpete]

I've never used the beads, and I don't intend to try them. I own a Coats bubble balancer, and I can balance a wheel in about 10 minutes. Why mess with something that's worked for me for about 30 years?

Fitted new tyres yesterday - took the tubes out, fitted them into new tyres, the Dynabeads stay in the tubes. That saved me 20 minutes of balancing by those times.

You've got to break down your wheels if you don't like the product to get them out. I used them in my 2009 Harley Street Glide and got a real bad vibration around 60MPH and up. After the many phone calls to Innovative Balancing's "tech support" (which is a complete joke because they don't have any tech support) they couldn't explain it at all... all they could say was that it had to be something loose or wrong with the bike. So, I spent several hundreds of dollars between having my tires aligned with the rim (the dot and the valve stem), having my Fall Away checked-out, having my rims checked for defects, having every nut and bolt checked-out and ultimately having the wheels broken down to remove the POS DynaBead BS product. Went back to weights and immediately lost the vibration. Will NEVER use a scam product like this again and will NEVER deal with these Innovative Balancing yahoos again. DON'T DO IT..!! I only wish someone would have warned me beforehand. When I finally called to ask for my money back, all Carol (the owner) and her minions would say was "we'll gladly refund any unused product". When I asked how I could get my money back since I had obviously used it, they again just said (like a broken record) "we'll gladly refund any unused product". This meant of course that I was not getting any money back. I've never received any money back from them for my "used" product. In summary, their little white ceramic beads that go so easily in the valve stem, cost me roughly $500 to fix and ultimately remove. Don't be a sucker... they're counting on it..!!

Yea how come they work for most people then? I'd have to say that at least 75% of people around here like them, including me. Just because you didn't doesn't give you the right to call the company a scam.. Get a grip, pal.

I have been using dynabeads then airsoft BBs for the last 30+ tires


most of my prevous bike had nice oz, marchesini cast and forged wheels. they usually take a quarter oz to balance. so beads would work fine

my zrx has some HEAVY wheels which took 1.5 oz to balance without tires as I found out for the first time last week. I mounted a used angel (pirelli) but the paint spot faded so I did not clock and just put in my usually amount of BBs. got a vibe above 80mph so I balanced it the old fashion way.

[Megadeus]

In cars, which have a longer radius from the axle to the tires' edge, I find a static imbalance to emerge around 45-55 mph.

If I balance said tire and I have a vibration around 65~75 mph, I am suspect of a road force induced imbalance. A road force caused by rim run-out or imperfection in the tires' construction.

Sometimes the road force imperfection can be alleviated by reclocking the tire on the rim 180 degrees. Most of the time it's a runout issue with the rim. ie... bent lip, broken spokes, etc....

The other kick in the nuts is that if you ride a bike with an imbalance for a while, say 500+ miles, you end up wearing the tire circumference into an oblong shape. (Think egg shaped) The oblong shaped tire induces a vibration no matter how many times you put weights on it or put balancing media into it. Dynabeads only work with a good true rim and a new tire. Worn/questionable tires (track take offs) will not always balance out because you don't know if it's worn evenly.

This is why some people bitch that dynabeads didn't work for them. Their used tires are F'ed.

Good for you! But I'd say you're the only person on this thread with a tire balancer.
For people like me who change their own tires and don't own a balancer, and have no need to since using Dyna Beads, they are a lot cheaper than taking the tire/rim or the whole bike to a place that will charge, what I consider a healthy fee to change and or balance them. I also don't have to buy and fool with lead weights.

I run tube tires. After the two minutes it took to put the beads in the tubes on the first set of tires I changed out, I have never have to balance any of other five pairs of tires in 30,000 miles. I don't change tubes until they are toast.
Bottom line for me is...they work! For an initial up front cost of 10-20 bucks, I'll keep using them until they stop making them.

Another thing, I've only been riding four years and had never heard of the paint dot on a tire until about a month ago so of course all my tire changes didn't line this dot up where it is supposed to go....Still no vibration! Even more of an endorsement for Dyna Beads. Next tire change I may have to try this dot thing out.

Where is the dot supposed to be again? Across from the air valve?

That's the light spot. Valve goes to the dot if there is one. You'd be surprised how good tires can be now. I've mounted many that didn't really need any weights.

I lucked out on the balancer, picked it up at a swap meet years ago for fifty bucks. But there are balance arbors out there that are really inexpensive, and It's not difficult at all to balance with one of those. Try Harbor Freight.

Thanks! I have four tires to mount soon so I'll be looking for the dot.
I've seen homemade balancers on here somewhere. I've had zero problems with the magic beads so I'll stick with them for the time being.
I've been wanting to try the air soft BB's in my truck tires but haven't gotten around to it.

Hey Kurt,

Next time you get your bike up to 60 mph .......... pull in your clutch and let your motor go back to an idle while the bike coasts down the road. I'm guessing that most of your vibration will go away when you do this.

Next time you want to have your tires balanced, call me. I'll do it for $250!

I wish he would have told us how he really felt about them instead of beating around the bush...

FYI, a tire doesn't "stay" in balance, even if it was a so called "perfect tire" when mounted to a good rim that was concentric and in balance itself. Tires wear unevenly-regardless of other factors and even if in balance with rim weights in the beginning of their life. You can not use beads & rebalance with rim weights or spin new tires for best balance spot but fact remains they can & do go out of balance from uneven wear.
I use the beads and have stuck with the 2oz rear/10z front as advised by the seller. They work for me & keep my tires spinning smoothly over the life of the tire. I don't sell them, have been a pro car & helo & industrial mech that also worked in a tire factory a good bit & life long bike guy. I also reuse them-they tirn a little black as the collect some stuff off the tire liner but still nice little round beads after many revs in there.
FWIW,The new Michelin Pilot Road 2's I just bought did not have balance spots on them. Years ago when I worked on the balance machines in a Goodyear tire plant the machine dropped a colored wax dot of various colors based on what spec it met, not based on the light spot, it was about if that car tire met an auto mfg's spec for being a OEM new car tire or it also indicated that the tire was unsuitable for any use. There were other checks such as human visual inspection prior to balance check & force variation check after the balance check.
I wish we could get a realsitic view from someone that works in MC tire place but they all seem to be foreign these days-all we get is superficial info from mags r.e., MC tires as they are paid advertisers in the mag so is "light info" & somewhat biased too.

So now you have me wondering if the dot on MC tires means anything or is of any real concern.
As I said earlier, I have never lined up any "dot" (didn't even know they existed) on any of the 12-14 tires I've mounted. No problems what so ever. I even reversed one of them half way thru it's life, no matching up anything, and it was still a smooth ride for the next 4,000 miles.

The dot is the light side of the tire. It is to be placed at the valve stem.

I have a Snap-On computerized balancer at my disposal. I have Dynabeads in the tires.

We had a customer buy a set of wheels that were way out of balance to the point they needed 3 1/2 ounces of lead weights. He couildn't bear that ugly stuff on his shiny new wheels. So we got him some Dynabeads and installed them. Worked very well on a very shitty set of wheels. I was sold. And I was quite skeptical prior to that experience but that's changed.

Just to be clear, you didn't try the wheel/tire assembly (with DynaBeads) on the computerized balancer. Correct?

[blackx70]

When I got my bike, there were weights on the front wheel. I replaced the tire and removed the weights. I did a spin balance and could not find a heavy spot. I have been running with no weight on the front and everything seems fine.
