Tried to get a new rear tire put on today, but they were booked for the day. They were closing early today, and they're closed tomorrow, til next week. Headed out with the wife on Friday for a 4 day get-away, and looks like I'll have to wait til I get back from the trip. Kinda sucks too. It's getting smooth in the center of the tire, and the edges are cupping. You can feel it when riding solo, especially in the turns. Actually feels better when two-up, so hopefully it'll ride okay while we're gone. Got about 8 or 9 thousand miles on the set, and the front still looks great. Will definitely be getting a new one next week.
Anyone else had an issue with their E3's cupping on the rear?

Not an engineer so maybe this will help a little.

In addition to riding style and habits, a lot of tire life has to do with things you have no control over such as road condition and surfaces.

tire cupping
For the life of me, I can't understand why we get so few miles out of our motorcycle tires. With todays technology and materials, the tires should be lots better than they are. Of course the manufactures are making big profits and the dealers can keep steady employment for the guy in the back changing tires. Of all the tires I have had on motorcycles over the past 30+ years this is the first for a cupped rear and if my new E3 cups I think it shows a problem in the tire itself. Would like to know what pressure folks are using to get the best mileage, I run 38f/42r.

I run 42 up front and 44 in the rear. I know it's a tad higher than recommended but it's what someone on the forum suggested for me. And after seeing the picture from the original poster, I can see that my rear is wearing in line with the others.

I ran 38 in the tire in the original post, as that is what my tire guy told me to run. When I bought the 2nd one, he told me to run 40 in it. I don't think this one is gonna get any better mileage than the first one. My front tire still looks great though.

I too only got about 7 to 8 thousand miles out of my rear tire and I keep an eye on tire pressure. I think I'm going to go back with the old D-402. I know folks say they don't stick or corner as well, but they last longer and I've never had problems with them like the sidewall cracks in the Metzlers I had.

I got better mileage by about 3500 miles than any other tires...I really need to change my riding habits...Cupping was pretty bad and i ran 42psi on rear...front is still perfect...
