Had a set of PS2s on my S4 - FANTASTIC tyres. Also had em, Eagle F1 (GSD3) and Toyo T1s, on my Scoobies. Didn't really notice road noise (mind you a scooby with de-cat renders you pretty deaf to most things!!LOL!

)
Current tyres are Dunlop Sport max on front, and Conti on the back. Road noise not an issue really.
Will be looking at PS2 or depending how I get on, the Contis (only had the car a month)
