using now for just over 1k km mileage - dry grip is awesome, wet seems slightly better than 003, but no complaints from me so far

cant help there unfortunately, i usually have music playing relatively loud, and tire noise was never a factor for me

Personal opinion - wet performance - PS3 outperforms RE004

What size are you looking at? Prices definitely vary depending on that.

With that being said, what i paid for RE003 is almost the same as RE004 (7 months already tho, changed at the beginning of the year).

PS3 definitely better in the wet.
Dry grip RE004 is marginally better in my opinion.

Cant comment on comfort or noise, not points which I look at.

Maybe others will be able to comment. Cheers!
