RE003 is not "semi slick" only the outside shoulder looks aggressive only. I m using it now, coming from PS4, I would say the dry performance of RE003 is better than PS4 and on top of that the sidewall of RE003 is harder than PS4, giving the sensation where the tyre don't flex as much as PS4 under hard cornering. But when it comes to wet, cannot compare with PS4, PS4 much much better in wet condition especially if there is water puddle. RE003 just can't give me the confidence on wet road.
