Are Dunlop D60 A2's noisy?

[only5kgt@uswest.net]

Greetings,
The question above is exactly the whole point for this time.
I have a set mounted on my '85 Coupe. This car has a *bunch*
of tire noise. I don't mean you can't hear the radio, but
it's louder than any car I've had- kind of like a 4x4 on
somewhat aggresive rubber. Yes, I've checked out the wheel
bearings (all OK) and the driveline has been ruled out (it's
directly proportional noise-to-speed with no change
on-off-throttle-neutral, etc.) The size is 185-60/14 on
stock Ronal R8s. Wheels have been balanced and tire pressure
is 32 all around. Is this hum just due to the chassis design
of the type 85? Or is there a quieter tire out there?
Any input appreciated...
Rob
