Can rubber in tire treads have "soft spots" that wear faster than adjacent rubber, thereby causing cupping? I replaced all four struts and tires
13K miles ago and now have cupping so severe that there is major road noise, which is significant because this 94 Sentra does not have the soundproofing that newer automobiles have.Apparently, I am not the only one with tire noise; I periodically hear automobiles going down the street with that same kind of tire noise.
