What Brand of tire? Michelins or Bridgestones? If I had to guess, I would say Bridgestones. There has been some discussion, that on the F the Michelins are a better choice. The Bridgestones don't handle as well, show wear a little quicker, and are noisier than the Michelins. I have the Michelins and have a wee bit over 500 miles with no such issues.
