They were the cheapest ones I could find with a tread pattern I liked. The cheapest 165 I found was this And they were more moneys.
To me I'd think they'd be more likely to float if you hit a patch of slush on the highway.
I liked this one better and hope it'll do ok in slush and snow, not pack the treads and hydroplane as easily. My hopes at least. Maybe a tire engineer will chime in? They're probably rock hard compound compared to blizzaks or michelins and not the greatest on ice but if I have any trouble stopping there's always curbs or other cars to slow me down. Everyone has their preference for tires and reasons for treads or brands. I had blizzaks on my caravan and hated them for the most part, packed with snow and you needed to spin to get through deep snow.
