These tires replaced a set of half-worn Michelin Pilot Alpin PA3 tires (I picked up a puncture in one of the PA3s and couldn't find a replacement, hence the half-worn). Compared to the PA3s, the Xi3s have similar wet weather grip and noticeably lower (but still acceptable for this type of tire) dry grip. Unfortunately, I can't comment on snow or ice performance because I never had a chance to try the Xi3s in the snow. The biggest difference was in dry weather feel - feedback was significantly muted with the Xi3s and there is also significant 'tread squirm' with the Xi3s. If I had to give each a subjective score relative to a summer tire (using a Goodyear Asymmetric as the reference summer tire), I would give the PA3s an 8 and the Xi3s a 4 - there really is a huge difference between the two. Ride comfort and noise levels are quite good with the Xi3s - a little better than the PA3s.
