When do you guys recommend removing this spacer? I have about 160 miles on 2015 750 hdi. Tracks seem quite loose with recommended air pressure and seem to be really pushing on side walls in ruts. I do know my one side is looser then other side. I also know that too tight is not good as its hard on bearings. Would like some other owners input on this. I did puncture a side wall today in a rut. Its very small and hoping i can patch it.
