Soft and super soft are what they say. Clay tires are a a little different some brands seem a lot softer than others like HB & Panther pink seems more like a super soft to me. JC Gold & PL MC feels a lot harder.

I have found that the clay tire compound really only works on a wetter track with good grip.
Where I race the clay tires either work really well or not at all.

Sorry for all the posts in a row but I have done a lot of tire testing the last few years. That may have something to do with me being broke
