I ran the 215/65/16 on mine. I didn't have them studded since rarely does ice stick around here for more than a few days and I didn't want to tear up the road. They just had zero grip on ice, even at parking lot speeds. I had them on when I went up and spent a day ice racing on a frozen lake up here, and they were basically useless, especially compared to the people running regular snow tires that just blew past me. The thing that really made me dislike them was having to replace them after less than two years, and that was back when I had a different car to DD and rode my motorcycle as often as possible. My current Duratracs barely show any wear despite being on my DD for over a year now.
**alright, thanks guys.
what ya'll think about these?
