I bought SVT wheels from Zoomin 3L a short while ago, and they are some awesome wheels with great tires on them. I put them on, and I notice they make kind of a wirring noise, kind of like a lower pitched whistle and it kind of pulsates when im going slowly. I have also noticed that when doing about 70MPH there is some vibration... Should I expect this from a 2 inch increase in rim size and brand new tires. Or do I need to take these tires to get them balanced?

check balancing and tire condition also have you tried rotating them to see if it makes a difference.
