Hi Guys and Girls,
Having tried numerous performance tyres (45 series profile and lower) over the years from all the major manufactures ..
I have found that directional tyres (arrow on side of sidewall showing direction of rotation when fitting) generally are the worst offenders for noise ..
when compared to asymmetrical tyres.
For years, directional tyres have been at the forefront of high performance tyres and we have all suffered with their major two downfalls in order to maintain high grip levels.
(1) Noise
(2) Comfort
Over the last few years we are seeing a change by tyre manufactures to move their high performance tyres into asymmetrical design and finally we have quieter tyres and and an acceptable level of comfort. A tyre that will ride the bumps (increased grip) instead of bouncing from one bump to the next.
A prime example of a high performance tyre is that of the Michelin Pilot Sports 3 which I have fitted to my Audi A5 (4.2)... my sunny Sunday sports car.

(a) Stops tread movement on high cornering loads (great steering response)
(b) A larger contact patch when cornering (fantastic grip)
(c) Stops the noise from the centre of the tyre travelling outwards (far quieter tyre than other performance tyres)
Compare the Michelin Pilot Sport 3 to the top of the range Michelin Pilot Super Sport ... they both still have these same design features

PS: My wife has the new mazda 2 Genki as her around the town car but I find myself really enjoying the fantastic steering (for an electrical assisted steering car) and the general all-round balance
