Front Tire Wear

that's what I figured, thanks! no real problems so far, I'll have to see if the new one makes any noticable difference when I decide I need it!!
 
I have heard for years that cupping results from tires that are out of balance and will be worse if the suspension is not working well, i.e., by allowing the wheel to hop. I don't recall ever having this problem on any of my motorcycles.
 
cupping tires

cupping tires

120/80/16's on both bikes? I think that helps contribute to the problem. They always feel like they're pushing and going to tuck under. Also that big area of unused rubber on the edge where it drops off like a cliff. It seems those fronts have a narrow contact patch when leaned over contributing to wear in one area regardless of tire pressure. Carter
 
You are probably right- the problem could be more noticable on the 16in fronts. I have seen it on the Dunlop K591 and Metzeler ME33 fronts that I have run. I always use correct pressure, proper balance and have the front suspension set up stiff. I am very hard on tires though and replace them often. Ride Safe, Ed.
 
You're right about the cupping on K591's. Ran the K591R's on my FZ750 street/race bike. Was really hard on the tires, trail braking, track use, extreme cornering loads, etc. They cupped badly and when they got really bad replaced them. The air pressure and balancing were always correct and the tires worked perfectly well until the tread got scarce where they were cupped. Always stuck like crazy and were very predicatable when driven at their adhesion limit. Thank God I don't do that anymore!!!
 
The softer compounds might also be more prone to this. I have always used the R compound on the 591's and the CompK ME33. That original FZ750 was a really nice bike- I remember racing a few of them in the late 80's- it was pretty fast back then. Ride On, Ed.
