19.5 Dually tires

[Tomtint]

So I have a couple F450s with the 19.5s .. One of the trucks is a 2021 Limited diesel that I pull our 5th wheel camper with. Truck has about 22K miles on it and when I got back from Fla last spring The tires were shaking in the rear.. Went to a couple different shops.. One was a truck place and they balanced them but it still shook.. I bought centramatics.. Still shook.. Bought 6 new tires.. Still shakes.. The wheels are balanced with weights and centramatics in between the dually.. Maybe take off the lead weights ? ..Dont know if that's messing up the balance using 2 systems.. ? .. On the other F450.. Its a 2018 V10 4x4 dump truck.. Has about 15 k miles and a number of years ago I put Kelly tires it for traction in the snow.. They shake like crazy over 50MPH.. same centramatics, ..still basically underivable over 50MPH. Brought the truck to a tire guy and he says tires have flat spots..need 6 new tires... So do I do begs, wheel weights or try the centramatics .. ? This is getting aggravating and expensive...

I have had the Kelly 19.5’s and the Goodyear 19.5’s. Basically the same tires, with no issues. No shaking like you describe.
Today, I am picking up a set of 6 Continental HD3’s.

I have a bit of a shake with my Kaufman trailer tires between 30-35, then it goes away. Could never figure out the reason. The bed kind of “hops” slightly between 30-35. Balanced all the tires and it did nothing.

I put these on my F550.

Off shore tire, but good pricing and tread is kind of a Continental copy. Never had any issues with them. No balance or shakes, good winter traction and weared good.

This may sound crazy but have you checked to see if you have one that is out of round? I ask because that is a problem I had several years ago.

On the 2018, did they spin balance the old tires first?
On the 2021, if tires weren’t it, next I would look at is wheel bearings and brake rotors

The 18 is at the tire shop now. That's the one that has the Kellys.. Tire guy said the first one he spun had a flat spot. .. But they all shake.. front and rear. Truck has 15k on it so i highly doubt it's a bearing anywhere. Those Kellys had beads, weights and now centramatics.. Never a good ride over 50mph.

Yes they were spun first and had weights on them. The 21 is pampered.. No mechanical issues whatsoever.

Have you had someone follow you taking a video? It might provide some insight, like wheel hop or wobble. Having the wheel weights with the centramatics doesn't matter. I have weights with mine, and when it through a weight, no change in ride!

The only way you can check if a tire is out of round is having a machine that can test for this. An out of round tire will balance but you need the tire machine that will test specifycally for out of round

Do they sit a lot, for long periods of time?

The truck only has 15K miles so it's not really used everyday. Sometimes its only driven 1x a week.. Sometimes it won't move for a couple weeks.

I got the 18 Dump truck back today.. The shop misunderstood my request and put my polished wheels on and they the old wheels in the back... I wanted them to take the tires off the polished wheels and put them on the steel wheels. .. That said, the only thing it hs now is the centramatics. Its drivable.. A little shake it the rear at over 60mph.. Now I need to get tires put on the steel wheels and start over.

I have brand-new tires on my Silverado. It sat for a week in this sub-freezing weather on concrete.
I drove it Friday last and all 4 tires felt like they were square. Drove it 40 miles before they felt normal again.

So back to the 19.5 debacle .. Had the tires taken off my polished wheels and put on the steel wheels, Balanced with weights and its decent to drive now with minimal vibration.. It's a dump truck so I expect a certain amount of a rough ride. Took the F450 Limited that has the new Bridgestones on it back to the shop that installed them.. It had lead weights and centramatics and it felt like the tires were square.. It was nothing short of awful to drive. .. The original shop took the weights off, removed the centramatics and put bags / beads in the rears... I drove it about 60 miles and it was absolutely miserable .. You couldn't leave a coffee in the cup holder without it splashing out.. So today.. Back to another shop.. Remove rear tires and suck out the beads.. rebalance with weights, no centramatics and re install.. Still sucks to drive... This truck was silky smooth with Continentals but they wore out at 20K miles. Im tossing the back four tires and putting rib tires on the back that match the fronts.. Its getting to the point where I'm going to get rid of the truck next...

Have you checked the drive shafts? I am pretty sure that truck has two shafts with a sort of hanger bearing between them. The rubbur in the mount where two shafts join go bad.

Carrier bearing.

Man that’s unfrigginreal.
I’m on my 4th set of tires on my Ram and every time I change tires, I fear an incurable vibration, but nothing has ever happened (yet).
My latest set looks like ag tires. I thought “now the truck will vibrate”, but it’s still smooth!

That’s a carrier bearing, The truck has 24k miles on it ..I can’t imagine it old fail that soon. The “vibration” has changed with every method of balancing. It went from a wobble at 60-65 and nothing at lower speeds. To tires feeling like they were egg shaped, to tires feeling like they had flat spots, to constant vibration to the point that you can’t pu5 a cup of coffee in the holder without it splashing out.. I believe it has to be the Bridgestone tires… I’m having them removed Sunday.. they have about 500 miles on them and have been a problem since day 1
