I worked in a mechanic shop for 4 years that did tyres every day and you sir are definitely right.
Even the slightest up and down on the balancer with an all terrain will cause a whoop whoop that sounds kinda like a wheel bearing gone

chevor I developed vibration issues with the dually. I suspect it was an out of round condition caused by the rears side by side dragging in turns. I mean the rubber has to give somewhere.

Wrong - what you are describing would suggest somehow a very rare situation where a major defect had gotten thru. I personally have not seen this in recent ( to me...40 years or so is recent ) years.

Modern tires damn well better be round.

If I saw the slightest bit of "out-of-round" on my balancing equipment (mine is an Eagle EB 1000) I wouldn't watch it for very long...off the balancer it would come...and I would have a warm, friendly loving kissie-poo stick-it-where-the-sun-don't-shine....conversation with my tire supplier....(just kidding..he most certainly isn't "that kind" of guy....!)

Obviously, without seeing the wheel-tire combo. this fellow has been complaining about, mounted up and spinning, I am in no position to diagnose his issues.

Have Scotty beam you back up to the present era - what you are describing COULD have happened 50 + years ago with "bias" tires.

Wheels on line purchase, Tires local shop... shop says wheels are bad.... I'v had them balance them twice and they change dramatically on weight... Then took to my usual tire shop (should have gone there in the first place) and he unmounted and remounted, got them better, but still not acceptable on the highway... He says its the tires...



I'm more inclined to believe its bad tires over a machined wheel....



Seems no coincidence that the Duratracs are Goodyears and that my dealer just went thru 3 sets of Goodyear SRAs on my OEM wheels due to bad tires... very hi road force and highway vibrations... 3rd set seem ok now...



Waiting for the tire dealer to call me back to try to warranty these things, but I'm sure he'll blame the wheels...


Thatís the very reason I donít buy Goodyears. All that Iíve ever had were bad in one way or another. They came new on two different trucks Iíve bought and less than 15,000 miles on them, the belts started separating. Goodyear of course wouldnít stand behind them. Wonít ever run Goodyears on anything again.

Not like the old days with "bias" tires, where any "out-of-round" under 5/32 was considered acceptable. Most every tire shop in those days had a "tire knife" - essentially a lathe on which you mounted your tire/wheel, and it was "turned" or the tread was cut down until it was round.

Could a radial tire be significantly out-of-round? My understanding is, if that happened, any kind of "quality control" at the factory would eliminate that.

What do you mean "cant be balanced". Any tire can be balanced, if you are willing to add enough weight. With modern tires, I would be surprised if it would take more than 4 ozs to balance. Anything over that and I would look for some kind of manufacturing defect.

I am having trouble getting my head around your description - something off here - once mounted on a modern computerized wheel balancer, and "spun up" it should be pretty obvious whether your wheel is below standard, (meaning bent, out-of-round, etc) or if it is the tire.

Assuming your tire man is both honest and competent, he should be able to show you what the problem is, by simply having you look at the tire/wheel combo. when he mounts it on and spins up his wheel balancer.
So, on the OEM wheels, I'm not an installer, but there is a limit to how much weight you can get on a rim, sticky or hammer on... and you are correct, 4oz, or less, In offroad tires like my 37s on the jeep, they require so much weight one needs to use internal beads.... 12-20 oz.

The new machines use road force... "A road force tire balancer, a state-of-the-art balancing machine, uses a load-roller to simulate the force of the road, and thereby ascertain the combined uniformity of a tire and wheel package. Road force balancers measure the force variation and runout of the whole tire and wheel assembly."

The tires had high roadforce, like 60... under 20 is ideal... took 3 sets of goodyears to get a balanced tire with low roadforce and thus no vibrations. The vibrations was significant. Ever loose a wheel weight ? for a quick trip no issue, but hours of driving, no way.

The duratracs have around 6 -8 ozs and spin true but when loaded vibrate.. RF around 30-40 right now...

So yes a manufacturing defect that cant be seen by the eye... But since it took 3 sets of SRAs to make my new truck drive like a new truck off the lot, and the duratracs are also GY, I'm guessing some where there is a gap in the quality control...

My guy has shown me the numbers, but I didn't buy the tires from him this time. Took a short cut to a closer dealer, and they are the ones who don't believe the tires are the issues..

Hah! I bought a 1/8Ē headphone jack to do this a couple years ago (before Radio Shack went under) and itís still hanging on a peg above my workbench

Yes, tires are not round....you can watch 'em hop on the balancer.
And makin' yer way around the round, it's different thicknesses too.
Can't be balanced....it's more common than you think.
