The way roads are crowned will also have a bearing on cupping. I live in Florida, and mine have always cupped and wore the same, no matter what bike, brand of tire, and they show usually around the 4.5K mark, then go down hill pretty quick. Metzler's, Michilen's, Avon's, Bridgestone's, etc. With the exceptions of my K60's, But they have 8K on them right now, and 6K were from out west in less than 3 weeks. Other than the typical squared rear from slabbing interstate, they're doing great. I run 36 PSI front & rear on the K60's, which is lower than on street tires I have had in the past.
