I have a 2011 Yukon with 20" tires 275/55r20. In the manual it says no chains are to be used on the tires due to low clearance. Does anyone know of some good low clearance cable or chains to use? I was looking at the Super z6 ones but don't know anything about them. if anyone knows some good ones for the size tire i have let me know which ones you have if they work good. Thanks
