Wheel weights

[kapinallinen2]

Brand new Duratracks.
Them boys tried their earnest to get these balanced.
Surprisingly, only one was off according to the road-force machine/technician. Dismounting and rotating 180 degrees took it to the "spec"
Had to dig into it, found out that automobile manufactures get the grade A tires from tire manufacturers, we get the grade B, forgot who gets the C`s, might be the 3rd world countries?
Anyhoo, been smooth for the past 40k or so miles.

I think road force puts natural road driving force, and sets the bead on the rim.

It's not about the type of weights used, it's the way that they're placed around the wheel. It's not normal practice to place weights (of any kind) on both sides of the wheel (180 degrees apart). In the lower right pic the amount of weight at the 11 o'clock position is about double the weight 5 o'clock position of the wheel. In the upper left pic there are seven weights at the 1 o'clock position of the wheel and five on the 7 o'clock position. And in the upper right pic there are four weights near the 7 o'clock position of the wheel and a single weight near the 4 o'clock position. It looks like only the lower left wheel has weights in one position on the wheel.

I will add this disclaimer: I have no experience with road force balancing. Nor do I know how it's done other than I can recognize the equipment used for that. Maybe this is normal practice when road force balancing? For normal tire balancing it's not normal practice to place weights in more than one location around the wheel. I've had cases where I split the required weight and attached half to the inside of the wheel and half on the outside when I had problems getting one to balance, or needed a lot of weight. But never 180 degrees apart because it defeats what you're trying to do with normal balancing.

Definitely not road force balanced. And when you don't use the weight that you hammer into the lip, this is how I have seen weights placed. Just not in that excess, and usually no gaps between strips. The tire machines I have seen used, depending on how it's configured, will show weight locations for both inside and outside of the wheel.

I get it, you don’t have experience balancing tires. If you did you would see that putting weights 180 degrees apart has a cancelling effect. Put 5 ounces at the 12 o’clock position and 5 ounces at the 6 o’clock position, and you haven’t affected balance at all. You’ve just made the tire 10 ounces heavier.

So in the worst case from the OP’s pic, I’m not sure the actual weight of each segment, but for demonstration purposes let’s assume each segment weighs 1/2 oz. So there would be 11.5 ounces at the 11 o’clock position, and 5 ounces spread out between the 5 and 6 o’clock positions. The net difference is that the 11 o’clock position is 6.5 ounces heavier. You could achieve the same result if you just put 6.5 ounces at the 11 o’clock position and no weights anywhere else. Make sense?

I’ve used computer spin balancers, static balancers, hell I’ve even used old school bubble balancers. None of them specified putting weights on the inside or outside of the wheel. I used to give the customer a choice of using taped weights or clip on weights when most stock wheels allowed them.

I do have experience with balancing tires. Maybe not ohsyicydoing it myself, but helping my dad don't growing up, and watching almost every set of tires I've bought in my 32 years of driving get mounted and balanced. And there are definitely machines that will show both inside and outside weight placement for the clip on weights. There was a time when tape on weights weren't a thing.

whoever balanced these have no clue what he's doing or just being too lazy to remove the old weights.
