I just ordered Dunlop E3 250, and curious how Dyna beads work. Does it balance the tire? In taking the wheel to the shop and thinking of using Dyna beads....
It's actually the opposite of that. They do little for static balance, since they move around in the tire. But they do an excellent job of dynamic balance since they reposition to balance the rotating tire. They start balancing at something around 25-30 mph, but you can't tell a tire is out of balance below that.Ive never used them but am interested in them as you all seem happy with them. I see how they counteract static balance issues, but they would nothing for dynamic balance but I guess dynamic isn't as noticable :dontknow:
Thanks for providing that BobbyMac. That was very enlightening. I had always wondered how they actually worked. I knew they would spread out evenly inside the tire, but I didn't have this knowledge or understanding about the whole process and the functions of the Dyna Beads.
Good info. I have had ours over 140 and have had no issues at all. Glass smooth. I have seen bikes without weights/beads ride smooth. I think the balancing has more tolerance on a bike then a car. So, I can totally understand what your friend is saying and it makes sense.I've had beads in for two tire changes now (re-used for the next set). This last time, out of curiosity, I took my rear wheel with the new tire (Dun. E3 250) and my old beads installed down to my friends' MC shop to spin test on his computerized balancer. We spun and re-spun about ten times. Usually it zeroed out perfect, but the readings were a little inconsistent. It only varied by a quarter of an ounce (the amount of weight to add or remove for the machine to indicate a perfect balance) but my buddy said you probably wouldn't feel a vibration until about 150 MPH with that amount of discrepency. I've had mine to at least 135 MPH with both sets of tires and it has always felt smooth. I was expecting a perfect read every time, but I'm happy and am sticking with balancing beads.
