I just swapped the OEM Summer Continentals for All-Season Toyo Proxes STII on my 4.4i Sport with the 19' staggered setup. I've only done a couple of hundred miles, but my first impression is that they roll smoother, are less noisy and more comfy than the Contis - bear in mind, they don't look as wide. I also live in the NorthEast and have a dedicated winter setup.

The Toyos cost me $1,086 delivered (+$99 for fitment/alignment), so, not a bad deal.
