I have a 2003 VUE, 6cyl AWD. I need to get snow chains but the owners manual says "If your Saturn has P235/65R16 size tires, don't use tire chains. Use another type of traction device...." Well, I checked and that's exactly what size tires I have on my VUE. P235/65R16. So what is the type of "traction device" I need to get for my VUE? What is the proper name and where do I look for it? Thanks, Cathy
