Wheel balancing, Needing too much
I took my wheels to a shop to get them balanced and two of were ablle to be balanced out just fine. The other two were way out more than the mechanic says is normal and he couldnt really balance. I saw the machine and if I read it correctly, one of them was saying 25 oz, and the other was saying I think 36 oz. Anyhoo. the mechanic said he pretty sure its got to be the tires that is causing it.
The wheels are a set of old school Vectors, and one of the tires is a bf goodrich and the other tire is a uniroyal tiger paw. What are your opinions ? There is nothing physically wrong with the vector wheels, they look great.

Sometimes breaking the tire from the rim and reseating it 180 degrees from the original position will help to correct a large imbalance. Your numbers may be too far out to correct without new tires. Maybe try another shop. Good luck with it. mike...

The wheels have a certain weight distribution to them and the tires do too. Rotate the tire 180* on the rim and see if it helps.
Good luck!

The 180 is the first move. Make sure the beads are properly seated by looking for lines on the tire compared to the rim lip. Those 2 tires could be flat spotted from sitting or sliding too. At 10 years old, you need to be shopping for replacement.

Fix a flat or slime in a tire will give you erratic balance readings also.
It seems odd that two different tires would need that much weight.
Are you sure the guy balancing the tires knows what he is doing or his machine is correct or calibrated?

I know the guy pretty well. The other two wheels balanced fine. However, what Stoutstuff said is possible. The car was sitting since September, so anything is possible. Anyhoo, the tires are 10 years old, maybe its best for new ones.

New tires are much less costly than body parts (for the car and for YOUR body)

It could also be that the machine the guy was using was faulty or not 'null' checked to start. Those machines have to be calibrated; and the parts they use to mount the wheels have to be balanced, as well.
Most tires/wheels take less than a few ounces of weights distributed as needed. With anything over 5 ounces, I'd guess the balancer has a problem.

As for it not balancing, Im wondering why your tire guy didnt break the bead and rotate it 180? I worked as a tire jerk for for several large parts stores through college and that was the FIRST trick we did when a tire wouldnt balance....and it worked every time.

As an alternative thought, what shape are the rims in? i had one where the tire was taking a huge weight to balance. rotating on the rim helped but not enough. Turned out the rim itself was out and had a slight buckle to it that was throwing things out.

Mark the wheels as to how much weight they need, THEN go buy and mount 4 new tires. Pay attention as to what wheels need more weights with new tires. See if there is slime/sealant inside.
Then you can determine what the problem was!
