Thats the biggest load of bs I have ever heard.
One question were the tires installed by a chain store or just a local tire place.If it was a chain store and you are not getting the satisfaction you deserve try taking it to another store as they are all interconnected,if it was a local tire place you might end up having to go somewhere else,have the tires rebalanced(probably the culprit as everyone else has said)and then calling your local Better Business Bureau and filing a report.
