front tire cupping

[Grumpy Goat]

My exBMW corporate bike has severe cupping on the front tire. I can’t recall the brand but it’s what came on the bikes from the factory and presently has about 6200 km on it. My experience has shown me it’s a result of requiring more rebound but that’s not something I can dial in anymore. Time will tell over future kilometres.

Probably Michelin Pilot Road 4. I and others have had cupping with those tires that were factory supply on our bikes. But in my case, I had a heck of a lot more miles on it than 6200 km - more like 8000 miles before cupping showed up. Continued to ride until it wore out (more) then changed to Dunlop RS 3 (and 4) and the cupping went away. No change to the rebound.
