I bet his tire is loose up there.

We have had a few people standing on that exact rack. It does not come close to touching the roof. I have seen tires that were not secured all the way and will make a ton of noise up there though.

I would check all mounting bolt into the factory tracks and than your bolts that mount to the rack. If thery are all tight, than it has to be your tire.

If everything is secured properly, and you still feel it's hitting the roof take some side profile shots and post them up.

Hope that helps.
