Have now read a zillion reviews and talked to Tire Rack. I will need to drive my CLK 55 this entire winter since my diesel is in CA. with my daughter. According to Henry at Tire Rack the LM-25 will not give me much ice traction while the Revo 1 will. The Revo 1 is soft like the old WS-50 that I used for years. I used the LM-22 last few winters but never encountered any ice. Has anybody driven with the Revo 1 or the WS-50 on thier AMG? Any info would be appreciated as i will order the tires in a couple of weeks.
