Sorry this isn't a Harley, but the Ducati forum is just only talking about chicken strips. So I have a new (around 800 miles) set of Pirelli Rosso II tires on and I noticed grooves that run the entire circumference of the tire. I've never noticed this on any of my other bikes. This was after a day of really pushing it in the twisties. Any input would be greatly appreciated!

Thank you!

 

They look like mould marks to me, part of the manufacturing process. Take a look at a new tyre if you can, just to check.

 

I've seen that on my latest set of tires (Bridgestone S21), usually after a track day, where the different compounds meet up but not that far down the edge of the tire. Looking on the Pirelli site, it is a bi-compound tire maybe a similar issue?


They go away if that's what it is FWIW

 

Just bought the 02 last summer
so are these the AEs where talking about or is it something else thats out now.
