They were the ones actually made in Carlisle. They were used on about half the minis originally. There's an Indian head logo on either side of the word Carlisle on the sidewall, along with Made in U.S.A. There are a couple of later series, the newest being made in China. The quality of the new ones is poor. I bought Cheng Shin, Hi Run, and Carlisle recently. The Carlisles sadly enough were the lowest quality of the three. Lots of people looking for the DIH ones for restorations.
