The original Michelin Pilots on my A3 Sport quattro (now @17k) are nearly ready for replacement, but have become so noisy I began wondering what would be a quieter, but still effective tyre. Then all became clear, thanks to HJ's advice page in Sat's Dly Telegraph. His common sense explanation to a reader pointed out as the tread goes down more tyre hits the road surface, hence more noise. Wish that had occurred to me!
BTW, I got a great deal on Bridgestones via a pal - being new, they'll be quieter, I assume.

While that may be true, it is still the case that some tyres are noisier than others.

Agree.I believe that tyres with an irregular tread pattern are quieter than oneswith a more uniform pattern.

If you measure carefully, you will find that the tread pattern on most tyres is irregular in spacing. This is done to avoid allowing the tyres to produce a pure tonal noise.
Although the actual noise level produced by the tyre isn't altered much, the human perception of a pure tone is that it is much more irritating than a broad band noise source.
Of course, in this case, the human perception is the important factor.
