If you are trying to save money – it doesn’t cost much to have the wheels professionally balanced. Probably less than what some of us spend each week on vending machines at work.
Just go to a good shop like discount tire and not some backwoods shop.
And by “set” the tires, yeah just proper mount and balance. ALSO – is there a chance the tires are those stupid unidirectional tires that are suppose to rotate a certain way? Maybe it is backwards?
DIY is fine with most things but tires is just something best left to a shop. If you had to pay yourself for the hassle, it would cost more than what a shop would ask.
