About 350 a set. I purchased them right after they were released , prices may have come down. I believe I paid 199/ rear - 151/front.I can't say how they compare to the pr3 , I came off a set of pr2s. These have more round profile than the pr2s. It took me a little whole to get used to a tire with such a round profile. As far as grip, I can't say if they grip at better . IMO I always felt that a good tire , was a tire you didn't notice, because if its not slipping around , you never notice it!
