I have a 2002 sc430. My first set of run flats sounded like truck tires about 10,000 miles. Because my dealer neglected to check my alignment when asked, they replaced them for free. Now on my second set with 17,000 miles. The second set also became very loud at about 14,000 miles. There is a lot of tread left, as it was with the first set. Does any one out there have the same loud noise. If this is a normal occurance because of alignment, than Lexus should make a mandatory service adjustment with maintainense. These tires aren't cheap. About $2000.00 a set. This shouldn't happen with so little miles and so much tread. All sc430 owners should make a class action to have either the dealer or firestone be responsible. The loud tire noise takes the enjoyment out of driving sometimes. Do any of you have this problem?
