Should I give the tire shop another try for balancing?
I had my wheels rebalanced at a professional shop as there was some "bounce" which I assumed was from using a bubble balancer. After putting these on the car the ride was worse. One of the other guys was following me and said it was really bouncing - and the shocks are newer and they seem fine. They did tell me that they didn't road force balance the tires but if I bring them back they'll do that. There aren't any weights on the outside of the rim.
Given how these look with the large weights and the stickies would you go back to this shop for a redo?

As has been posted many times use a shop with the Hunter-GSP9700 machine. I can't say if that much weight is legit. Others may know more.

1. Did you tell them not to put weights on the outside of the rim?
2. How old are those tires?
3. An out of balance tire doesnt cause the car to bounce, a front out of balance will cause a vibration in the steering wheel, a rear out of balance will cause a vibration in your seat.

I'm going to take no for $200, Alex.
If they were unable to properly balance them, they should have said so. If the tires were unbalanceable, they should have told you so. They had their shot.
Cut your losses and have a professional do them.

Whomever balanced that tire doesn't know how to properly balance a tire. I would take it elsewhere and have it load balanced on current equipment. I've been in the business close to 40 years, and bubble balancers were obsolete before my time. They work, but the new loaded mode balancers are much better. you want both planes balanced, the inner lip of the wheel and the outer lip. When multiple weights are seen on the same plane in different locations, it's a sign of incompetence. A properly balanced wheel will be weighted in only ONE spot on it's respective plane.

In my 40+ years of balancing wheels, I've never seen a "STEEL" wheel balanced that way with stick on weights on the inside. also if done correctly, you don't need to split the weights either. IMO you need to find, at least someone with a road force balancer, and here's the key, and someone that knows how to use it. Now if the tires or wheels have a problem, out of round, flat spotted or bent, then all bets are off.

If your friend who was following you home saw your car "bounce" then you either have a tire with a thrown belt or a tire that is somehow out of round...either would show up on a high speed balance machine. Go elsewhere.

My last 'thrown' belt was on Kelly-Springfield tires decades ago...
That'd possible but a long shot IMO...

Moral of the story, don't go to places that offer coupon deals!

The Hunter GSP9700 is a great machine. BUT, the operator needs to understand what he/she is doing. In the hands of an untrained individual, that machine will still produce poor results.
A highly trained individual can still achieve great results with a lesser balancing machine. He/she needs to understand the concepts of "Out of round" and "Imbalance" and be willing to measure, index and adjust wheel/tire assemblies.

Go somewhere else that has better balancers and personnel.

They are 5 year old American Classics manufactured by McCreaery Tire and Rubber in Indiana, PA (plant code is CY). I don't understand the double height stick-on weights.
I'll start the easy search for a shop with a Hunter system. How you evaluate personnel is a lot more difficult.
Thanks for all the help. Will more on with more work on my '61.

One of my peeves ... Not many shops can/will take the time to index. The shop I currently use, we discussed it, and they did a great job last time on my daily driver. This time no such luck. Spin'r on the road force and slap the weights on. Like talking to wall when they're busy - do you feel any vibration? .... Thats not the point I want the least amount of weights necessary.

The shop that does my balancing on all my cars will actually walk you through the whole process and explain it to you while you watch. He's not listed on the national list but he know his machine.

However... if your car is bouncing, and that bouncing can be seen by someone following you... you have more than a tire balance issue IMHO.
You have a bent rim... or bent rims.
You have out of round rims.
You have out of round tires.
You have shifted or ruptured belts within the tires causing them to be out of round.
You have seriously flat spotted tires.
No amount of balancing is going to correct these situations.
