Timing could be better as snow is on the way out . . . but these are an amazing tire. Total new design from Vee and they are really headed in the right direction for a snow tire. This is the 4.8 PSC Compound + studs.
I also have a 4" version (non studed) that I will report back on concerning non-snow performance.
