I run the TRUE snowflake winter tires, Blizzaks on my 04 duramax and 2015 duramax in the winter. W965 IIRC These are true studdless winter tires. I get around 20K miles on them, go on/off as needed during the winter mounted on a seperate set of rims. Last about as long as a studded winter tire.
There are not many true studdless winter tires avaiable in LRE, but the blizzaks and Michelin ice are available.
I've towed with them, and they are fine in the winter. Like any true studdless winter snowflake tire, they will wear fast,especially in the summer.
Dry traction is like any studded winter tire, not great, but wet traction is very good.
Interestingly, when the original snowflake rating came out it was for studded or true studdless winter tires. Now it seems like this has gone the "M&S" route where lots of tires have snowflake rating. And the difference can be pretty dramatic.
