Dynabeads, do they really work?

[Hockster]

I used them in my last set of KM2's. I installed them new and they seemed to have a sign wave balance pattern. It felt like every 1-2 minutes I would feel this odd what felt like a balance issue. It wasn't a bad vibration just this weird noise that wasn't very loud just a bit annoying on long trips. Removed them and had them road force balanced and no more weird noise.

Interesting. I was winding what your of terrain you were running on with success. I've heard of problems with the beads not being able to settle down and balance the wheel when constantly jostled from off-roading or even highway joints and potholes.

Is there any alternatives? I have trouble keeping wheel weights on my wheels. My UCA knocks them off.

Thanks for the help.

How is your uca knocking them off?

I have not used beads. But I have a ton of experience with balance issues. I can tell you that 100% of the time it was due to lug centric wheels rather than hub centric. I think the main issue with lug centric wheels is that when put on a balancer they either use the center bore of the wheel, or they use a mickeymouse adaptor that tries to use the lug wells.

I bet that the folks who have issues are using lug centric wheels.

BTW, the reason wheel makers use lug centric is not because it's a toss-up on which is better. It's because they have to make only a few versions to fit many trucks if lug centric and they need to make like 5X more if hub centric.

On your truck the hubs are machined on a lathe. Where a hub centric wheel mounts it's perfectly true. The car makers doesn't have to hold a tight tolerance on the holes they drill in hub for the lug bolts. Maybe yes, maybe no. Too much chance for error.

On the last set of lug centric wheels I owned, Centerline Racing Wheels, I had the 35" goodyear tires balanced maybe 40 times at 5 different shops. In the end we found that we could balance a tire perfectly. Take the tire/wheel off the balancer, put it back on, and check and it would several ozs off. The last shop I used was a custom wheel shop and for $50 a wheel then machined and inserted custom rings in each wheel to make them hub centric and amazingly the tires rode perfectly after that.

Hub centric also puts all of the load as a sheer load on the lug bolts. I suspect that they are not designed for a sheer loads. Factory wheels are hub centric and the hub carries the load.

Lug centric sucks.

Good info but I am confused on your last point? Was that a typo or do you not like the Hub Centric for some reason?
