I run 36-38 on my Saab and Volvo on the WRG2s. I am not sure what the safety issue would be. They completely tear it up in the snow. I am getting a set for my '13 this week to replace the Conti's which I will run in the summer.
I run the WRs all year round on the Volvo in the Northeast and get 50k miles out of them.
