Can't offer a comparison to others vs. V70's (which my car came on, 175's and 235's, K60 which I believe is medium compound), however intially really not a fan of V70's as I found the car really skittish and could spin the wheels aplomb not seemingly trying (and yes I admit, I have driven in the cold/damp/wet so my own fault). However, my opinion has now changed dramatically after a dry day out and up & over the Hartside Pass (you southern boys are so unlucky where you live) a week or so ago. I have clearly never got them anywhere near hot enough before and as I went up the pass (with its many little squirts and hairpin bends and a knowledgeable lead car to follow and help me understand what a decent speed for the road was) the car came alive! By the time I reached the top I felt like a hero (I suspect my pace was fairly limited in reality) but the car felt unbelievable, so planted, so much grip, so much confidence inspired. My initial reservations were a product of my driving in the damp and not actually understanding how to switch them on. Now I would recommend and I will probabky be buying again rather than changing to something else in case they aren't as good. Good lesson learned by me as part of my ongoing seveducation
