They probably won't balance them for you because they can't guarantee it since the tires are from elsewhere. Plus, they'd probably say something else was wrong with your car that costs a lot to fix just to spank you and your wallet
I don't know. But I do know I bought 4 new tires at NTB in Houston, Tx and had a problem with 2 tires and the guy there didn't want to rebalance my tires because I didn't buy then there. (At his store)
