A large percentage of tires have a significant dynamic inballance.
Some cars are not fussy about dynamic balance - others are very fussy.

I only have experience with a sum total of five (5) tires.
And, so far, they've balanced just fine with my HF static balancer.
As I said, I have BBS wheels (standard BMW issue) so maybe that plays a role.
Also, the 5 tires were all bought at the same time from Tire Rack.
Dunno if that has an effect at all (probably not).
I removed all the weights first.
I then balanced them (none needed more than a short strip of weights).
Pretty much that was it.

Car never vibrated.
If it did, I'd take it to the shop.
But it didn't.
You were lucky and got a set that didn't really need much balancing.
My guess? Continentals or some other tire that lists at $200 or so
each.. And you got lucky that they needed a multiple of 1/2 ounce to
balance out.

You get a tire that needs 1.75 to 2 ounces to static, and it may need
4 to dynamic balance it. You might have 1.5 on the outside at one
spot, and half way around the tire another 2.5 to 3 on the inside.

Get that on the front of a twitchy little sedam like a BMW320 with
only a static ballance, and your hands will get a good massage from
the steering wheel, even if the bumper doesn't jump.
