Hi, my 2013 Legacy has been making a buzzing noise from the back that I thought was cupped tires. Changes with speed. I replaced the 1 year old tires with another brand that I like on two other cars but when driving away from the tire store the same sound was there! It is noticeable enough that people have asked me what it is after riding in the back. I am slow & easy on cornering and the alignment has been perfect. My original tires lasted 80,000 miles! Any ideas before I take it to a shop?
Side note I'm not a fan of these 17" low profile tires. There isn't any sidewall to flex. It is such a rough ride compared to my old Impala and LeSabre! I'm tempted to buy 16" used Legacy wheels, saw some 2011 ones listed locally for 65 each.
