thankz buddy 
there hard but the wet grip is super,ive tested them in accelerations n hard braking.
the sound is v less,not v noticable,i even saw the gs2 but that tyre was hard as rock :s
dont really think there bumpy but yes due to the 60 profile the guy told me to avoid the dithes :S even though i argued these are just 60 not like 40 or 45
