How can I reduce tyre noise?

I would like a car that cruises quietly without the tyre roar that a lot of cars seem to suffer from on run flats e.g. my current BMW 840d coupe and Mercedes E400d estate.

A lot of factors can contribute to tyre noise, and run flats in particular can suffer from this as they have a stiffer construction to resist punctures. Generally speaking the wider your tyres are, the more noise they will generate, while all-season and winter tyres are also generally noisier than summer tyres.

We would suggest looking for an alternative tyre with a low noise rating. Looking on blackcircles.com, if your Mercedes is fitted with 245/35R20 tyres you could look at the Pirelli P Zero PZ4, which has the lowest noise rating of 68dB in this size.
