Counteract DIYK-5 Do It Yourself Tire/Wheel Balancing Beads Kit - Off -Road, Light Duty Truck Tires, (4) 5oz DIY Bead Bags, (4) Valve Caps and Cores, (1) Core Remover, Injector Bottle

Tried as a last resort since no shop around my area can balance my model A wheel/tire, not easy to install with tube tires (took 30 minutes per tire) but results seem good. I can’t detect any shimmy or vibration at 45, which is my max comfortable speed.

I was skeptical that this would work. I have a cargo trailer with tandem torsion axles. It rides very smoothly even over rough terrain. The wheels were not balanced and I could feel vibrating at certain speeds. These glass beads really work to completely eliminate any vibration. I even bought an extra for the spare which I will rotate with the others. This is a worthwhile investment.

Purchased to use in flatbed trailer tires. So far I am impressed with how it works. Trailer does not shake & vibrate like it used to. Installation is a different story. Took a little bit to learn how to get beads to actually go into the tire, but once I figured it out, it was not terrible bad.

I am not a professional mechanic, but I do have a tire machine and balancer at my house, so take it for that. I run 37s' on my Superduty. I needed new tires... I have heard of these beads but have never used them. I actually dredded this job. 37" tires are hard to dismount, hard to remount, hard to lift... hard to put back on the truck, nothing fun about working with them. I talked to a few people and decided this is the way to go for big tire. I mean I could have thrown my back out putting these tires on my spin balancer... but I didn't want to. So I dismounted my old tires and to my surprise there were beads in the tire. Actually one of the tires didn't have the bag broken... so I made sure that wasn't going to be me. I opened and dumped the bag into the tire while I had the bead broken. I set the beads and mounted the tires... took her for a spin... no weird vibrations @ 40 (in the dark in the rain). I will see how the do at highway speeds, but I am confident they will work. So how do they work?Cut an imaginary disk out of "rubber", like a frisbee... now hold that disk right in the center and spin it about your fingers, like a pizza or something... it runs smooth because it's symmetrical and you are holding it in the center. Now imagine there is a rock on the outside rim of the disk and when spinning that disk it wobbles because the rock takes the disk out of balance. But we have magic beads... how do the beads know where to go to counteract the rock? How do they know where to go??? I imagine the rock pulls the disk outward... this is like the waiter and tablecloth trick... The rock is pulling the table cloth away from the table... where are the beads going to go? directly across from the direction of pull... so there is weight opposite of the rock and it counteracts the force. correct me if I am wrong.... I think this is how they work.

First, these DO follow sound and proven physics, so they should work in principal, BUT:The quantities in the charts available, published online and included, give very generic numbers, based only on the width of the tire and type of bike. For a dual-sport with 21/18" wheels with rim locks, 2 oz are given for the front wheel and 3 for the back. However, the weight required for the static balance I did before was 4.6 oz and 5.7 respectively. Therefore, double the amount spec'ed and no guidance for what to do if it's not enough, nor how to tell, etc.The product comes with special valves with "filters" to keep stuff out of the valve, which are really just a little cap added to the end. They didn't hold air after a day of riding and, worse, I COULDN'T GET THEM OUT of the valve stems without resorting to drastic means, namely pliers to essentially rip them out. They would unscrew, then click back into the stem so the only thing to grab was the plunger tip, but the threads reengaged each time! Final extraction revealed the "filters" to be gone and the tips of the valves to be bent, preventing them from sealing and catching in the threads preventing the valve from coming out.If twice as much as is specified is what's actually required, the expense is not worth the trouble. Now, I'm not sure what to do with the junk in my tires, since I'm not convinced it's doing what it's supposed to and the wheels can no longer be balanced conventionally.Originally, Counteract said I could get a refund without having to return the product. Amazon requests the product back, though, in order to refund the purchase price. Then Counteract customer service was unwilling to do anything about it, finally saying they weren't accepting any responsibility because I had to weigh it out myself. As if. Even if I were an idiot unable to use a digital scale, there's still the crappy valves.

Im pretty new to the use of beads but all i can say is wow! I've never felt offroad tires run this smooth before!

These beads are slow to install...30 minutes per tire.

The beads are the best way to balance your tires. Used them for years and no more ugly weights

I was kind of sceptical at first even though there are many YOU TUBE videos out there. I decided to put them into my new tires on my Burgman 650. Before it was starting to get shimmy at about 110 km, but after I inserted the right amount ( 2 OZ as per chart I downloaded and removed all the stick on weights) I tested it out and even at 135 km per hour it was smooth. It worked perfectly. I highly recommend it.

No crei que se fuera a notar pero realmente se mata una diferencia en el manejo , si me gustó

Motorcycle tires. Kit was missing the hose! Not a big deal.

The media could not be loaded. la instalación fue muy fácil1-sacas la válvula y pones un gato de bajo baja la llanta asi como la foto que salga el aire de la llanta2-luego perforas el bote y lo tapas con cinta TAPE y vierte dentro todas las perlas tapas el bote con su tapa y manguera3- conecta la manguera al pivote dela llanta y vacía las perlas si se tapa que un ayudante empiece a subir el gato poco a poco y las perlas entraran muy rápido si es necesario destapa el agujero perforado del bote para que entre aire y sigan fluyendosi no tienes ayudante con el pie puedes ayudarte para subir el gato asi como en el videolas probare y posteare si son efectivas en la carretera

None of the 3oz bags actually had 3oz of beads in them. They were 3.9, 3.85, 3.75, 3.75, all weighed using a calibrated scale. Good easy to use kit though.
