Ok, I have no complains about the Kumho Optimo tires but not liking the thick band of ribs on a good portion of the sidewall. Is there a reason they have these ribs? It looks like crap and putting on tire dressing doesn't go on smooth as the excess oozes into the cracks and then it will sling over the fender wells no matter how much you wipe off. Not putting the tire dressing on the ribbed section looks ghetto by applying it everywhere but the ribbed area. Any thoughts?
