Cabin noise

(And actually, we have heated seats and I don't want pillows because in the winter that would defeat part of the heating operation.)

I'm embarrassed to admit this, but here goes...

I thought my Z was super-loud on the road noise from day 1 (I'm at about 1800 miles). Getting ready to go on a 1400 mile trip next week, so I thought I'd check my tires. Holy crap! I was between 45 and 48 psi. I'm sure a few of those psi are from going from 20 degrees when I picked the car up to 70 degrees now, but I have a feeling they were overfilled from day 1.

And I'm usually really good about checking my tires, but my gauge was in my truck and it's kept one place, the Z another. But I should have checked.

End result is this: road noise was cut by over half when I went to 35 psi. Like you can actually carry on a conversation now! My wife is very happy. And the ride is much improved though I definitely see the need for sway bars with the properly inflated tires.

So check your tire pressures (along with everything else) - it makes a huge difference.

I found that my change to Hankooks, although much larger, offer a quieter and softer ride. Psi level also contribites as Scott mentioned. Strangely, I hear very few pings in the wells from debris. Is it the tire tread configuration?
