Towing with Dedicated Winter Snow Tires (snowflake rating)

I run studded Cooper M +S on my F 350 throughout the winter. Tow the TT a few times up ski hills. Good traction but get only maybe 2-3 years out of them. Hakkapelitta LT2 studded 275 R 70 18 that is rated for close to 3700lbs are something that I would consider next time. Have double the studs compared to Cooper. Just installed Hakkipelitta 9 studded on my wife's vehicle and have had great results.

We live 5 months up in ski resort. Lots of snow/ice.
