<div class='quotetop'>QUOTE(priussoris @ May 1 2007, 03:59 AM) [snapback]433136[/snapback]</div> There is definitely something wrong with your tire / tires. Check them again - even have the tire rep put them on the rack and carefully inspect them. You may have a large roofing nail embedded in the tire... as the head of the nail hits the road - it smacks it, making a noise that you can hear. You may also have a bulge in the tire - separating the tread from the casing - that hump would also make the sound you are talking about. Either way - you have a problem that needs to be carefully evaluated NOW... before you have a catastrophic tire failure while you are driving.
