Advice needed please. Does anyone have any recommendation for quiet running tyres, mine are currently ' Falken Linam' 195-70-15's and due for replacing due to age, although listed as 71db they do seem to be quite noisy, either that or in old age I remember the van running quieter on the road and it has had sound proofing to stop the drumming.

I'm afraid 69db is as low as it goes for our tyres.
I use the quietist pirellis I could get
At the end of the day we're the victims of tarmac quality.
I can say fresh tarmac is a joy to travel on

Turn your stereo up

db is a logarithmic scale so there’s quite a significant difference between 69 & 71.

Every 6db increase is an effective doubling of volume, if I'm remembering rightly

I have Falken Ziex ze914 tyres at the moment.... good value for money and pretty quiet...

I didn't know that
It's still a din at 60mph

It's more complicated than that - I went away to have a read because I had 3db, 5db and 6db in my mind

So from some sound specialists

3db, is a doubling of the energy needed to make the sound (and about what most people would perceive as being louder)

6db is the sound increase from a doubling of the voltage in an audio environment and the mathematical derivative of log10 squared

10db is what the human ear perceives as a doubling of the sound level.

The 3db rule is the one used in the world of HSE

Best example I read was if one typewriter is 60db, then 10 typewriters would be 10 times the energy, but would measure 70db and sound twice as loud.

Next you get into frequency weightings, where actual sound frequencies are weighted according to the sensitivity of the human ear, more than one weighting scale exists !

Coming back to the OP, the difference between 69db and 71db might be noticeable, but only marginally. I would be much more concerned about grip. There's only 4 skinny bits of rubber on the tarmac, which you need when cornering and braking.

Thank you all for your input, I think I may try the Michelin Agellis as they available in the size needed, as in another post I will have to replace the current carpet lining again so may also try more soundproofing and accoustic carpet. Re turning up the stereo I would but the dogs don't like it, that's only for beer and bbq trips The typewriter explanation was very clear re db, but I fear that younger people would not understand

If they are inquisitive I suspect they will just ask Siri, or one of her friends
