19.5 Dually tires

You buying tires from same dealer?

I bought the tires from a dealer who first balanced them with weights, and used the centramatics. They wobbled at 55-70 mph. Same dealer removed the weights and centramatics and installed beads.. they shook just as bad. Maybe worse at lower speeds. Then took the truck to 2nd dealer,
Who removed beads, put on weights , no centramatics and now have wobble at 60-65 and a hop at 40-45 mph

I had a Suburban with a vibration. New Michelins did not help as much as I hoped. I wonder if the driveshaft or drums were out of balance. I gave up. My Dad driving it never took it up to 70. He is not as fussy as I am. He used to be.

Tires on mid 70's Dodge van were bricks in Cleveland Ohio winters. They smoothed up after the tires warmed up after 10 miles.

Does the truck shake when it is on a heavy duty post jack and the tires are off the ground spinning at 40-60 mph? Do you see any wobble in both directions? Look to see if the tire runs round and look to see if the tread runs true. How much weight did the wheels get when running rim weights?

I thought someone asked if you had a follow vehicle with a passenger to video the wheels to see if any show wobble at speed.

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.

All new automotive tires have a "mounting guide ring" around the bead area. This bead/ring is concentric with the tire bead to insure proper positioning when mounting.
If the tiny bead on each of your tires is not concentric with the rim edge, the tire is not mounted accurately.
New tires have red, yellow and or white dots to aid in mounting too.
