Saw these at an online shop.

Looks like these are made by some Italian mfg. They're definitely not Jacos.
BTW, I also noticed that these Ital. made tires go by shore rating and not the color dot rating. To me the shore rating is easier to go by. Just wondering how the shore rated tires compare to the color dot rated tires because the color dot rated ones have different kinds of rubber other than just one being harder or softer than the other.
