I've always doubted if wheels are properly balanced by Honda when delivering new car. But didnt do anything. A few months ago when my car mileage was 15k kms, I got the wheels balanced just for the heck of it. I could see weights already there, which means Honda did try to balance them when car was delivered. But after balancing car is silky smooth at high speeds, in a way it wasnt before.
My advice - if you know a good tire shop, there's no harm getting wheels balanced again. Nothing can go wrong, it won't cost too much and will last a while before balancing is needed again.
