I just got an '07 GTI last week and after driving it about 700 miles (road trip), I got a flat! The entire interior side wall of the tire was torn to shreds, but luckily no damage was done to my rims. I took my car to the dealership to replace the tire and when I rode off the lot I heard a weird "whoop, whoop, whoop" sound coming from the passenger-side rear tire (the spot where the tire popped or so I think it is coming from there). I immediately brought it back and had them look at it, they claimed there was no problem. I brought it back the next day to have the alignment specialist look at it and he said that the rim and wheel ran true and the alignment wasn't the issue. So my service rep said the noise wasn't even that noticeable and that I should drive it for like a hundred miles and see if the noise goes away or gets better because it will all be covered under my warranty (not the advice I wanted to hear for a brand new car). Also, if i stick my fingers behind the rear wheel-wells on both side, on the driver side i can easily fit three fingers down the back length, but i have a little harder of a time on the passenger side. Any ideas? Am I just overreacting and the sound is the normal sound of the 18's?
