"KO2 have been discontinued, replaced with the K03. I ordered up a set today to replace a set of KO2 with too many miles on em."
According to BF Goodrich's website they still make the KO2 and you can still order them. I bought five LT295/65 R20 ALL TERRAIN T/A KO2 tires last Friday. The website also says the KO2 is a snow/ice wet pavement tire and the KM3 (not KO3) tire is a mud tire.
