I know this is an old thread.
I just took my American Elite's off after 14,500 miles of use. Front air pressure was always 36-38 and the rear was 40-42 psi..
The front was worn out. The rear was not worn out but was scalloped and howled so bad they were changed out. Was not handling like it used to either.
The original Dunlop's had 17,500 miles of use. The rear was howling badly and scalloped. Again, front was worn badly.
Put on Michelin Commander 2's this go round-have never had Michelin's on a bike. They are a nice looking tire but did not like the made in Thailand. Have Michelin's on 2 cars and p/u truck and have always been happy with them.
Have not ridden with these tires yet.
