Hi,After speaking with my dealer about the noisy tyres on my Vectra 1.8vvt they said i could buy brand new ones for the discounted price of £45 each fitted.This was for Dunlops.I initially agreed but asked to take out a similar car with different tyres to mine to listen to the noise.
I went out in a 1.8 sri 07 plate and while the tyres where slightly quieter than mine,there wasn't that much difference.I'd say about 10% quieter.
After this test drive it was quite a shock because i thought the other car would be whisper quiet.I wasn't prepared to pay £180 to have my tyres changed for the sake of 10% difference.
I since have had the clutch replaced under warranty today(modified clutch from Vauxhall,lovely and smooth again instead of juddering up the street!) and they gave me a Corsa 07 plate car for the day.The noise in this car was even worse than the veccy and there was a constant droning sound from underneath.The tyres that were on this car where Goodyears so i have come to the conclusion that its not all the tyres fault more that its lack of sound proofing because all the cars i have driven with different tyres sound the same as mine.
I have since put 2 layers of underfelt in the boot and that made a big difference.I then temporaryly fitted underlay felt under the bonnet card.This made a massive difference to the sound and have now been looking into buying a felt material that is fire proof.
This is what i'm thinking of getting...
So anyone else thinks that their tyres are noisy then unless you can get them for free i wouldn't bother with the expense.Sound deaden the car instead.
