I have put a deposit on an AMG GTS. Superb car in 99/100 respects but the road noise when motorway driving is too much for my liking (and certainly for Mrs BB). So a condition of going through with the purchase is that the Michelin Pilot Sports are changed with tyres with a lower decibel rating - the road noise from the 75db noise rated Michelins is incredibly intrusive. I have chosen Dunlops with a 70db rating but they seem to be hard to come by....a few questions if you'll humour me. Will this make a significant and discernible difference to the noise inside the car? I think so...simply in percentage terms they'll be 8% quieter., although the db ratings refer to road noise outside the car...... And the second question - a long shot - has anyone on here been faced with a similar problem of road noise and solved it another way.....I'm thinking whether I should consider some form of sound proofing...

Thanks for your contribution Chaps. And you're right it's definitely a daft problem to have in the context of other significant worldly problems....but it is an irritation. Maybe it's the design of the AMG itself that exaggerates the road noise of the tyres (MPSS)...some commentators on YouTube have said the boot area can act like a sound box........If only Kumho did tyres in the rights sizes, I'd have them like a shot....
Thanks all.....dynamat looks very interesting. Certainly an option. We've managed to locate the Dunlops which are alleged to offer 4db less road noise. That should give a decent sound reduction and if not sufficiently, the dynamat will be added into the mix.....as to the question on 'am I sure I want a GTS'.....well yes! Chris Harris gives it a decent rating; it can't be bad at all in that case. I'm looking forward to trying to live with it longer term than I have some other cars. Always been a big Merc fan.

Interesting comments on Dunlop's.....I have read that these ones are specifically designed for extreme performance vehicles and have huge grip which explains why the fuel economy rating is a bit down. I'll report back after taking delivery of the car. I'm keeping the MPSS's anyhow so have a back up....and now I know about dynamat... I'm covered, hopefully.

Just reporting back now I have the car.......and I'm happy to say that the 70db rated Dunlop GT Maxx tyres appear to have made a real difference to the intrusive road noise that I had experienced with the 75 db rated MPSS tyres. And they do seem to have an amazing grip. This car is so much more composed than my former F Type R Coupe and the power is transferred to the road effortlessly even when the roads are wet and when using a heavy right foot. The Jag in comparison used to slip and slide all the time (it had Pirellis).... may be this is why my wife describes the AMG as 'boring' and the Jaguar as 'exciting'....I certainly know which one I prefer.
