I put Pirelli Weatheractive tires on my ST back in October and I love them. Great handling in wet, dry, ice and snow., in the last month here in Twin Cities area the weather has been rather interesting going from the 50's to sub zero in a day. I been able in one day start with dry pavement to wet/rainy to ice then snow these tires are fantastic! Great grip and road feel in all conditions, the original factory tires were okay in wet and dry and just worthless in snow and ice, best money spent in my opinion.
