today I replaced the Michelin tires with Firestone tires on my Sportage in the hope that the road noise would disappear. But no luck. Road noise started months ago when I had the Michelin Hydroedge tires rotated and it has become intolerable. I have adjusted the tire pressure as recommended by many posters but no luck. I love my Sportage and don't want to get ride of so hopefully some of you really smart folks can help me out.
