I have ~800 miles on my coupe. When I first got it, it had some tire balance symptoms so the dealer Road Force balanced all four. Along with doing that they lowered the tire pressure to ~29-30 from the recommended 33! But having said that I think that these Bridgestone Turanzas are noisy & rough riding and am thinking of replacing them.
So my questions are:
Did the dealer (along with the balance) lower the pressure just to lessen the balance symtoms?
Do you think the dealer would do anything about swapping the tires with another brand?

Thanks
Jack

The tires have no warranty from the dealer. Your only recourse would be through Bridgestone/Firestone but chances are VERY slim that they would do anything. The only thing you can do would be to wear these down and replace them when it's time.
