How important is changing the oil in the front forks? Some say, do it every year. Does this improve tire wear? My front tire looks bad, no cords showing, just looks like the left side is cupped in spots . Low oil in shock? I have read on here somewhere that the Dunlops wear on one side like that, and to change up the manufacturer, maybe a Michelin or Pirelli would last longer. Oh yeah, I'm on a 08 Fat Bob, fat tires...expensive.
I have discussed this topic on a lot of different motorcycle boards over the years,uneven front tire wear.Typically my left front tire wears faster on the left face,opposite the single brake rotor.Which I believe to be a major cause of this uneven wear pattern.
Other ideas include making longer left turns,more friction from riding right side of road crown,bad wheel bearings,etc etc...a definitive answer has yet to be found to my satisfaction.It may be a combination of factors,yet low fork oil isnt high on my list of suspects from my research on the topic.
I do find it highly unusual that you are riding a fatboy and having this problem,my past experience is harleys front tires in general wear evenly up front with high mileage,while their rears deliver half the life.The opposite of the metrics in general.
