Re: Tire Noise - Bridgestone Potenza??
Thanks to both of you for your suggestions.
The tire pressure has been spot on (30/33) both before and after the re-balancing and in case I failed to mention it, the tires are RFTs.
The BMW Factory rep was at the Dealer when the re-balancing was being done and agreed that BMW will pay for it, although he stated that this is normally a Dealer/customer charge. Sounded like BS to me, especially for a new $80,000.00 car with 2200 miles on it. Actually, the tires never felt like they were out of balance, but after only 2,200 miles, perhaps the cupping or abnormal wear wouldn't have been present.
The noise is still present from 25 mph on and is rather annoying. Sounds like wind, but I'm sure it's coming from the tires.
I've driven on highway sections of concrete, asphalt, with the windows down/up, even moved the tranny into Neutral to check if the noise was coming from the Steptronic , but the noise was still there. While driving through a tunnel with no other vehicles, I rolled the windows down and still heard the noise reflecting off of the tunnel sides.
I had a similar problem several years ago with Bridgestone S-03s on a Porsche that I owned and Bridgestone acknowledged the problem (a "bad batch") and replaced them. Perhaps the present problem stems from a "bad batch". Car was delivered on 7/25/06.
Thanks. All further suggestions or info will be appreciated.
