It may be they are using "bubble-balance" machines. Apparently they worked
pretty well with unbelted bias ply tires, or maybe the profiles were higher
then or the front suspension less sensitive. Anyway, lateral imbalance makes
bubble balance useless these days, but the machines are probably a tiny
fraction of the price of spin balance machines.

If you've ever had a ceiling fan with flimsy blade mounts you've seen the
effects of lateral imbalance. If a blade is not rotating in the same plane
as the others no amount of diddling with weights will correct it.

IIRC, they only spun 'em once. At discount, they spin until they are
done. OTOH, I had to NTB tires that were so bad, no one could balance
'em. That's why I've never been back.

In my case, they were spun on a machine at all locations.

I like the way tires were balanced at a shop back east... On the car!
That way, the entire spining assembly is treated.
