Centramatics-Any experience

Bendare2: Thanks for the answer. Also the Hunter Down Force Balancer gave me a very smooth ride. 28,000 miles have passed since and apparently Centramatics is the correct answer.

I can understand Centramatics working at speeds say above 30mph.

Serious question: When do they start working, is it from the start (1mph)?

Had centramatics installed on my 22.5 steers.........work great for me.
Brochure says they start working @ about 22 MPH.

The large dynabeads worked well on my last coach.....U320 Foretravel....no complaints.

Tires have a better life when balanced......money well spent.

Happy trails.......Ol'Ben

While a good question from a physics standpoint, I wonder how much "out of balance" one could feel at speeds so low the Centramatics would not work.

Regular balancing was done for years and it really didn't do much.

Then came high speed spin balancing, which was better. But people never balance their tires like they should (which would be every tire rotation). Tires become out of balance as the wear and each tire will wear differently.

Now there is road force balancing because regular spin balancing wasn't doing their job. Just had my under 1500 mile tires that were spun balance rebalanced with road force balancing. They were all out of balance and are still slightly out of balance, but within road force specs.

I'd say something that will dynamically balance the tires and wheel assemblies as the tires changes is much better then the "old" way.

For me the tires will get balanced when installed and then let the centramatics care for them as they change due to wear.

But under 30 I'd say you couldn't tell and you're more likely to feel road surface changes. From what I read you won't feel tire problems until at least 30mph and anything under that is usually a bent rim problem.

I had dynabeds on our Mercedes and at low speeds I would hear them sloshing around.
Than at some point the car start having higher speed vibrations.
I did normal balancing with next set of tires and no issues.
I have 2 centramatic rings on front axle of my conversion. Smooth ride.
My Centramatic are older ones, where balls roll in dry groves, while newer design is filled up with oil.
Still I don't have to worry about freezing or corrosion in CA, so it works for me.

What do Centramatics do that the larger RV specific Dynabeads do not do, for hundreds less? Just asking for my own education.

Lots of Dynabead failures. Many times they don't balance, google videos on youtube, sometimes they end up clumped . Sometimes they're melted and pick up rubber and turn to big black balls. Mostly in motorcycle tires.

Centramatics proven in the 18 wheeler industry. None of the associated dynabead problems. No difficult transfer/cost with new set of tires, like dynabeads. Buy them once and then sell them or transfer them when you get a new coach.

Here are Dynabeads removed from a tire. the big black balls are the beads that picked up rubber. That could be an issue.

I have been using Centramatics for years and would not use anything else. I tried beads once and had a mess when the tires were swapped. Should have used a vacuum cleaner.

I'm convinced. When I have valve extensions installed I am going to have them installed.
