Interior Noise?

[Lyn]

I'm pretty new to Boxsters and have had my 2003 S for less that 2 months. About 99% of that time has been spent with the top down enjoying as much of the spring time in Phoenix as possible. However, I've had the top up the last few days, because the outside temp has finally gotten to the high 90's and am surprised that the interior noise level with the top up is not a lot less than with the top down. It's a different kind of noise, driveline related instead of wind related, but noise nonetheless.

The noise is best described as a constant "thrumming, or resonance" that is the same under partial power, or with the clutch disengaged and coasting. I've got the stock exhaust and Perelli P Zero tires and it is definately not engine noise. I'm wondering if this kind of noise is a normal expectation with a Boxster and I should just be patient until the high summer passes, or am I hearing more than I should. I've got 6 months of warranty left and want to capitalize on it if possible, but don't want to be chasing ghosts either. Thx for your input.

Could be a wheel bearing, does it change with vehicle speed?

I've got Perelli P Zero tires

That there's the problem

Had them on my 01' S, they were so noisy it was unbelieivable, I also heard a sort of howl come from them at times

If the noise bothers you, replace the tires with yokahama's or a more quiet breed of tire

I wouldn't put Yoko AVS on, they get even louder as they wear

Type of tires and how many miles you have on them make a huge difference for noise. Rear Michelin PS2 tires replaced after 28K miles on our 997 made the car much much quieter inside

28k miles out of ps2's? were you on the cords?

I'd consider myself lucky to get 1/2 that!

Lots of good input and all is appreciated. It's likely the tire issue, as many of you indicated and I guess I'll have to live with it for a while as they were fresh when I bought the car and I hate to contemplate putting out the bucks for a new set of tires already.
