Astra 2001 1.6 16v estate fitted with cheap tyres produces road noise and a 'drumming' when run over 'town' viz., urban roads.
It has been found that this increases a lot with relativity small increases tyre temperature (say atfer a 40 mile hispeed motorway run @70/80mph or even being in hot sun or several hours)?
Anyone with any knowlege/experience of this phenomeon or similar?

Astra-G suspension doesn't suppress tyre noise very well so noisy tyres are very noticeable - it occurs with cheap or expensive tyres, my OE-fit Michelin XH1 were very noisy. Subsequent Goodyear NCT5 were much quieter and my current Goodyear Excellence are quieter still.
Be aware that "acoustic brake pad warning devics" are fitted and start to hum, like a tuning fork, when the pads need replacement.

Thanks Ruperts Trooper,
This begs the question why is the Astra G suspension like this, is it the front or rear? dampers or springs. The design is similar to the previous model.
Are there no kits to obviate this?
I suspect only some models exhibit this esp estates.
I why if sound deading panels would help?
Its just about tolerable when the tyres are cold, but irritates when there are hot?
I'll certainly look for the quietest tyres when I next change.
I take on board the acoustic brake pad warning but this is optional?
THe drumming I experience is as much a feeling as a noise and is exaggerated by blocked ears!
This may of course be down to the fact of having a quiet car for once.
Regards
brian

The 2001 Astra-G I had was the quietest car I've ever had for road noise, it was fitted with Michelin Energy tyres.

The acoustic brake pad warning is standard across the range on Astra-G.
I have a CDX saloon, with slightly more sound deadening than other models and road noise is certainly higher than it's predecessor a Cavalier mk3, particularly from the rear axle.
