Hi all,

My mind might be playing tricks with me but it seems the raod noise from the front of my car is getting louder - it increases with the speed of the car - nothing really below 15mph - but there after increases with speed and is worse on better surfaces, sounds almost a rhythmic hum - question is whether this is...

increased road noise as my fronts are close to replacement (Pirelli pzeros; or

Something more sinister.

There isnt any knocking on turning that I can hear

any suggestions would be appreciated

Anthony,

I would guess with the Pirelli tires needing replacement, that is the source of the increased road noise. I had the same issue with both front and rears when my Pirelli's were worn and ready for replacement as the Pirelli's are notorious for noise.

I would suggest you do do a search for tire replacement threads on this site and you will get several making recommendations for other manufacturers ( other than Pirelli) that have worked out well for folks.

When my Pzero's got worn down they got VERY noisy.

Jim

its widely known that pirelli tyres give a lot of noise as they wear. but however try to get the noise and gently swerve left and right to see if noise decreases and increases more one way than the other as this should discount that you maybe have a wheel bearing issue! if noisier to the right then generally its the left hand front wheel bearing(loaded side) and vice versa!
