I tried searching but could not find any info on this. I would like to get a spare wheel for my MS. Should I get it with or without TPMS? Will having a fifth TPMS sensor screw up anything? Will running a wheel without a TPMS sensor put the car in some sort of a limp home mode, disable autopilot, etc.? I am going on a long trip and would like to order the spare from TireRack today... Thanks!
