thinice,
No!, and Yes!
For 2500 Sprinter wheels your local tire shop should be OK, but a truck tire shop would
be better as alot of car tire shops cannot mount/dismount Sprinter tires.
Don't ask me why, as I do not know! Maybe their jacks and equipment are not heavy duty enough for Sprinters.
If you have a 3500 Sprinter, the local truck tire shop can balance them, but without the
centering adapter that the MB dealers have, they may not be able to get them centered
in the balance machine precisely enough (they depend on a taper that's supposed to engage a radius on the wheel, but they only get a sharp edge contact point on a 3500 Sprinter Van wheel unless they have the MB wheel centering adapter.
Someone out there must have a lathe and a bunch of about 3/8" scrap steel and could go into the business of making 3500 centering adapters that fit the most common truck tire shop
balancing machines.
I can get the dimensions, but do not have the lathe!
So, yes, you might get a good balance job at a high end local truck tire shop, and then again
maybe not if you have a 2500.
If you have a 3500, the possibility of them getting a really good balance job (that takes out the imbalance without trying to compensate for wheel center runout) is a bit less.
