I am sick and tired of getting stuck in the snow (level ground) with the Dunlop SP winter sports I have on the '94 wagon. These tires are 'recommended' by MB and others (?). They are good in the rain and at speed and noise is good but they are no good at climbing hills (my driveway) and snowy roads. Couple that with the lousy traction control MB put in the '94 and '95 and I am having a hard time getting around the last couple of days. It's embarrasing. Quatrro drivers are laughing. What do you use on your wagons for snow tires?
