Tires - DynaBeads

Recommended Posts

Anyone try these?  I've heard nothing but good things about the beads. I've read that they can balance a tire better than weights. Was wondering what the thoughts here were on em.   On that note, I'm thinking about starting to do my own tire replacement. I saw some videos on guys mounting tires by squeezing the tire together with zip ties to get them mounted, using something like windex to lube up the rim a bit.  It looked easier than using tire irons and less of a chance of scratching rims. It doesn't look too healthy for the tire though.  How all this started was that I've got a vibration problem after I had a new front tire installed.I don't remember noticing anything til I had the new tire installed.  I'm pretty sure its in the wheel/bars. It doesn;t feel like it's in the engine. I don't feel as much vibration in the pegs or the tank. It really feel likes its all up front.  I replaced the tires with a new set of q3's so it's not and probably never was a tire installation/ balance issue. Basically, when people you trust try to tell you in so many words that the problem is all in your head or just ride slower, you might start to take matters into your own hands and do the work yourself. I've put every single mile on this bike from 0. I know when something isn't right.  I've worked on  my cars and it's time I start wrenching this bike as much as I can within my skill limits.  There's a lot of things that are out of my skill level but I'm going to learn as much as I can. No-one cares as much about my bike  as I do :)  Let me know what you all think about the tire mount and the beads.

They work...until you have to change the tire, then little beads everywhere.  I used them, and sold them at the shop i worked at a while back.  When it came to change the tire i took it to iron pony and completely forgot about them.  Tire dude was not happy.  They also had eroded away so there was a conglomeration of powder, sand, and beads.

They are nothing but a gimmick in my eyes, and yes I have tried them once. Would be curious as to what Hoblick thinks about them, especially since he has done so many tire changes.

He has put them in my tires ;)

 

no Gimmick they are in every tire I own. Also ran in most semi fleets and large commercial tires, dump trucks, semis etc as spin balancing them is hard and costly. I used to work for Arctic Express and they had a fleet of 500 semis, all running Equal, a different brand but same thing as Dyna Beads. All commercial truck tire shops have them and install them too

OK so I guess I might try them.  The whole reason being, as I said, I want to start changing my own tires. If they work they would make getting a good balance on a tire a lot easier in a home garage.  I did see two videos where the beads broke down and stuck to the inside of the tires. Kinda curious about that since ceramic wheel bearings last forever. Im no physicist or polymer engineer so I wont even pretend to know anything about how durable ceramics can be.  The yays outweigh the nays so I'll probably give them a shot on my next set of tires. If I ride much more with 330racing ill be buying more tires probably by July.   Trying (and failing) to keep up with him.  I'm not expecting them to fix my vibration problem. As I said  I don't fault the tires there.  I'm leaning towards wheel bearings now but I will probably start with having a shop do a TB check/sync.  Along with checking torque on the bolts and checking engine balancers. I may try that myself. I only have 8k on the bike but its really starting to feel like wheel bearings.  I'm not feeling any pulsing in the rotors but I'm not ruling them out either. At $600 a pair for new oem, they will be the last thing I replace. I may even try a pair of low mileage take-offs. One other thing I need to find out is, how much the Brocks 4 into 1 full system changes the harmonics. I also had a lighter set of bar ends on last season and I went back to the stocks.  The stocks don't feel like they went on as snug as they should.  But, again, it really feels like its in the wheel somewhere.  Anyone have an opinion the zip-tie method of tire installation?

And btw, If I'm being stupid about something please tell me. I would rather  be called out on being dumb and learning something from it than messing up my bike.

Am I reading your post right....racing? Dynabeads are not recommended for racing per the manufacturer. Something about the soft tires.

They are fine for racing. The issue is with soft compound tires and warmers you can end up with some sticking. DOT race tires and Medium compounds no probs. Soft compounds with prolonged times in warmers on HI causes issues because the beads are not moving in the warmers and the soft compound gets sticky when hot

I asked him about them.  He mentioned he

has seen them become embedded in tires.

Other than that, wasn't much said about them

except that some people like them.

Sorry guys!  When I said 330racing, I meant the member here that goes by 330racing.  He's a damn good rider.  Much faster than me.  He keeps me on my toes and then some. A good guy and great fun to ride with.  I haven't had this bike on a track yet.  I'm running q3's currently. Not sure how soft they would be on a hot day at the track if I do decide to go. I will definitely think about it and do some more research.

I second this. My dump truck runs them.

Put me in the nay column fwiw, they may work, but I think a couple lead weights mounted on the wheel is better than a bunch of shit spinning around inside my tires. Car or dump truck? Whatever, my motorcycle that routinely goes over 100, no thanks.

Even better for bike going over 100. They are active balancing, so balance is always right. They reset and rebalance every time the tire stops and starts. With lead weights they only balance the time they are put on, balance changes as the tire wears so the balance is never perfect after the first time. Plus lead weights are ugly on the wheel, fling off, need to be duct taped on for track days, peel your paint off when removed, cost more to have done and if you get a lazy tire guy they probably were not balanced perfect to begin with. The beads cost about $3-$5 for enough to do the front and rear tire and you put them in yourself one time and done. As opposed to an average of $10-$15 a wheel as shops are charging around me to balance and then going in and paying again if on flys off.

I bought a $20 Harbor freight wheel balancer, and I have the Honda weights that snap in and grip the wheel center spline, no fly off. Easy to do, and no extra wear on the tire where there was never designed to be wear.
