My 407 cupped too. My dealer replaced it free of charge but they didn't have the 408 in stock so they gave me another 407 and told me that when a 408 came in they would replace it again.

 

3400 miles on my 407s (09 SG ) I can hear the front roaring while coasting or breaking at 45 down to 25 mph ( radio off ). Sounds like an knobby tire at the moment, no handling issues or visual signs of cupping. I was thinking of getting it changed out at when riding season was over or at my 5k service, I figure its only going to get worse. I heard some say dealer would not do anything and others say tire was replaced but had to pay labor? Haven't read the details of warranty but I would assume warranty would include labor on this. What should I expect to hear from my dealer when I bring it in? I am asking as of Aug. 09 ( recently ) because I am sure initially there was denial of any issue.

 

Replaced my front at 7000 miles because of cupping. I had to put another 407 on. It will have to be replaced soon because of cupping. I check the air pressure every week and even tried running a little extra in the second tire but it didn't help
