Out of round steer. Will centramatics cure this shake ?

you can get a tire shaved but centermatics wont fix a out of round tire.

 

how do you know for sure your tire is out of round? Did you specify in a post i missed?
Like someone else mentioned, use counteract, and pull your brake drum off and bang it on the ground. I had this happen twice to me. Just a little rust or debris between brake drum and hub makes a big problem in vibration and steering wheel shimmy. Use a wire wheel or scraper in between threads on hub. Just the SLIGHTEST amount of rust like i said throws that wheel off going down the highway. check inside of brake drum too.

 

I would indulge in a little hysterical too when seeing those weights it will take to pound a square tire round again.

My heavy truck alignment was done at the old peters and springs in down town baltimore. I don't know if they are still around.

 

You could use that tire on trailer.

Centermatic is tiny steel balls with some kind of grease inside of tube. No control whatsoever. I assume when truck is running they will sit about bottom because they are super greased and no force bringing them up only gravity holding them back. Basic physics. If they have to move around with tire most likely will stuck on heaviest spot.

What I am trying to say is Centermatic has nothing to find a right spot to balance your tire.

 

Ask Kevin Rutherford for advice.

 

Take a good look at your wheel hub and rim for cracks. We just replaced one but not before it bounced a steer all to hell. Crack didnt show up until after a good power washing. New hub and tire, all is well again.

 

Never said it would. Just saying get the alignment done with new set. Using laser it works . Computer align systems need calibrated every cpl yrs

 

I disagree on the Centramatics. Since I installed mine on the steers the hands feel much better at the end of the shift.

 

Ok, well they are an expensive option and hard to imagine how that thin 1/2 diameter tube filled with shot could balance anything out of whack on the externe left or right side of the tire. I suppose if the center of the tire is where the balance issue was confined to they would help. Counteract beads are a fraction of the cost of centramatics and do a 10 times better job balancing out the whole tire and wheel assembly.

 

i fail to really grasp how either centramatics or counteract ect work. my mind tells me that they even out tire wear by constantly changing the imbalance vrs actually balancing the tire. if anything centrifugal force should cause them to seek the heavyset part of the tire to collect. the heavyset part of the tire will want to travel the longest path. seems like the beads rolling around under centrifugal force would seek the heaviest part of the tire vrs the lightest part like there claimed to do. as the part of the tire that is travleing the longest path will also have the highest cyntrifugal force. unless there is another force at work that i am not thinking of. i have tried them before and had worse tire wear than with spin balanced tires. the downside balancing tires with weights is they do need to be periodically re-ballanced as the tire wears.

the only other thing i could think of would be if the actual bounce of the tire against the asphalt re distributes the beads of away from the heaviest part. but then they will be re-distributed every time you hit a bump in the road then the tire would have to oscillate to balance again. even if that is how they work it still would be less than ideal as the tire would need to oscillate after every time they are disturbed in order to balance. with seems less than ideal. i feel that they really only help by constantly changing the imbalance so the imbalance is in a different place every time to help keep the tires wearing true. vrs actually balancing the tire.
