PhoenixGTS

as really quiet. They are pretty quiet, but I noticed that they actually get noisy as you are slowing to a stop, for example coasting up to a stoplight. But then I thought wait a minute, when you make a u-turn in the S4 the front differential (or center I am not sure) makes a ton of noise, so I started to think, maybe the ST115s are so quiet that what I am hearing is a differential noise. Odd thing is that I do not recall the "right before stopping" noise with the stock Blowtenzas or the Pilot Sports I had on for a short time. Any thoughts?
