Centramatic. Whats the point?

Ok. I have read up on the above and can see a point with big trucks where they put on 1000000 miles a year. But putting them on trailers where you can easily get your wheels balanced at a fraction of the cost. Is this for full time rv ers who put on high miles?

yep, there may be no point 4 many and little value for most others.

also beads can be put INSIDE the tires for a fraction of the price.

or latex sealants added which will help balance AND plug leaks.

besides, a set of SPINNers would do the same thing and lOOk mucho cooLer...




________

the 2nd set of tires on my unit went ~10k more miles b4 replacement while using the C'matics...

but most trailer tires DIE from age and INactivity, not mileage.

otoh with disc brakes the weighted pie plates do help keep the wheelz clean...

the stream interior ride is maYbe a tIny bit betta' with the plates too.

cheers

You can get your tires balanced but your hubs will not be balanced and an out of balance hub can shake your trailer to pieces.

I vote for Centramatics...they are not that expensive, and I believe the physics of it.

Having the running gear, tire, wheel, hub and drum, as an assembly, is near impossible to have done.

Beads can cause wear inside the tire, since they roll around.

Centramatics, not only take care of the running gear, but they also STOP vibration damages to the trailer that can easily be caused by the running gear.

Additionally, keeping the running gear in proper balance, adds to the tire life, and minimizes blow outs.

We have yet to have one customer make any complaint about their effectiveness.

Airstreams are not cheap, and sometimes to better protect your investment, you should add other things, that unfortunately, some owners disregard, causing unnecessary expenses later on, which can be huge.

What's the deal about beads wearing out the inside of the tire? Anyone have any problems with this?

I've used both Centramatics and DynaBeads, and both work. I prefer the DynaBeads because of several advantages: the amount of balancing can be adjusted by simply adding more DynaBeads if the running gear and tires are way off balance; ounce-for-ounce, the DynaBeads provide more balancing since they stay several inches farther away from the hub of the wheel thus providing much more centrifugal force; and the DynaBeads are much, much cheaper (and can even be reused if you want to go to that amount of trouble).

Again, who's ever seen tire wear from the inside from the DynaBeads, which have long been used extensively by over-the-road trucking companies?

I can't comment about Centramatics vs Dynabeads but I will tell you that the Centramatics do work! My cabinet drawers were coming open during travel. I had the tires balanced which didn't help (probably hubs out of balance?). I installed the Centramatics and haven't had a drawer come open since. To me that is proof, and all for only 0.3% of the cost of the trailer!

I just bought and installed Centramatics recently on Lucy. It ran right at $50.00 per wheel including shipping.

I installed Dynabeads on our 34' as well as my wife's 2006 Honda. The Airstream appears to be OK, but the Honda suffered tire tread separation on 3 of 4 tires approx. two months after the install. It may have been a defect in the run, but......

Since I am currently installing new axles on the trailer I went ahead and bought a set of Centramatics as well.

Before installing centromatics on my 68 shake damage was becoming a real problem. Since adding them a year ago I have have FAR less of this. They work.

Some hubs can be balanced.

I have no doubt that they work. I see the physics. I guess if you are experiencing problems with drawers coming open etc and having exhausted all other measures, $200 is worth the money.
