What makes tires not hold balance?

Mark wheels and tires to see if they are moving relative to each other.. otherwise its a tire problem.
 
They did say they were out of balance. Wouldnt they unflat spot in my 11 mile drive? I dont know if they checked them for out of round.

With my experience with Goodyears, over numerous sets, on numerous vehicles, no weights were lost, no movement between the tire and wheel, they were initially balanced, and any 'Set' due nylon cap ply, or sitting for a bit before becoming 'round' again and running smooth was taken into account. Balance machine was calibrated, runout of the wheels was checked, the "Smartweight" feature if using a Hunter Roadforce balancer was turned off, etc.

I just think they are poorly constructed. It wouldn't surprise me to hear that other brands, especially 3rd tier brands, are too.

If you bought these at Americas Tire, they will probably swap them out for some better quality tires.
 
The only tire I have bought that lost balance was defective from the factory, the carcass wasn't centered in the tread mold and it took a few ounces to balance on factory rims. The other 3 were OK, but now I know to not accept a tire that needs so much weight compared to the other 3, especially after they needed to rebalance it....
 

What makes tires not hold balance?

Assuming they were properly balanced, the answer could be:

1) "Driving by touch"...i.e., bouncing off curbs and other road hazards
2) Poor quality off-brand tire from a Chinese or Indonesian sweat shop.

That's about it.
 
If they appear to get unbalanced after sitting parked overnight, it is likely the tires are "flat spotting".

Modern radials will never flat-spot overnight. It might be a concern if one is storing a vehicle for several months, but even that possibility is rare. I routinely store a few of my cars for months at a time, and have never had such an issue...even with Douglas tires.

I wish I could have got better tires from Americas Tire but they were way out of my budget. These maypops were $440 otd mounted and
" balanced". A comparable set from Americas tire would have been $1200

Well I don't hit curbs but I do drive on my rocky dirt road every day.
 
I think the tires would meet to be removed and the bead and rim surface cleaned of silicone, or anything lubricious.

@CapriRacer would know more. At least you know that's the problem

I hesitated to post in this thread because I wanted the OP to provide more data.

So first, tires don't suddenly go out of balance or suddenly out of round (with a few exceptions).

Tires do go out of balance and out of round over time due to irregular wear - a misalignment condition.

So one of the things I'd be looking at in the OP's case is the road. It's not uncommon for people to forget that the problem only occurs on a certain road.

And since wheel end vibrations tend to be worst at the resonant frequency, which usually occurs in the 50 to 70 mph range, it is not uncommon for people to miss this.

And tire moving on the rim? I've only seen this when silicone was used. I've seen small slippage in some cases, but small enough not to matter.

I am running lower air pressure. 25 psi as it smoothes out the wash board dirt roads I have to drive on every day. Maybe I need more air pressure? I have seen tires slip on semi trucks. Never thought it would happen on my 3600 lb jeep.

What size and load range are you running?

Happened to me from too much tire lube from mounting. I posted about it in a couple threads. CapriRacer gave me some info with teh possible silicone so I had shop clean everything and redo it. I couldn't find direct post but this is the long post I put on DriveAccord when it happened. One tire slipped 180 degrees, the other either 90 or 270.

Wrong/Excess Tire Lube
 
I'd mark the wheel and the tire relative to each other. See if the tire is slipping on the wheel rim.
My tire guy does this routinely. Always says to take it easy for a few days and if I see the lines no longer line up to let him know. They've never moved.
