I appreciate you pointing that out...I had actually seen that post. While his post has lots of information in it, it didn't really deal with equivalancy of compounds between Jaco and CRC. CRC only seems to have a few compounds FR/RR compared to quite a few for Jaco.

Perhaps I'm just too dense to decipher it myself, but it would be helpful to hear others' experiences with CRC vs. Jaco tires
