If you had them for years, then you have used the KO, and you are right about them, they did get bad/mix reviews and even BFG now compares the KO with the KO2. I was aware of it before buying the KO2. I have found threads that it was obvious misunderstanding by some, who didn't know they were reporting on KO2, but were in fact, reporting on KO, giving the KO2 some bad reports. I stand corrected, but the KO2, were only available in last year or so.
Regarding claim of Snow flake, yes, several very well known manufactures put that on tires, that didn't meet those specs. In fact, it became an issue that DOT is considering mandatory testing and not leave it up to the manufactures association (Trust them to monitor themselves, I don't), as they have proven to be as honest the the VW Diesel gate. Which is why I read every third party review when they did test the KO2, not KO. As I don't give tire manufactures the benefit of the doubt. I believe I brought this up, in one of the threads here.
Okay on the fine print, those words weren't found in small print on KO2, so I have no reason to suspect your fine print applies to KO2.
I do recall reading that fine print on many other tires, though most refer to a wear indicator, not a percentage, it seems to be a common warning, which is the reason why you replace your tire, when it reaches the recommended wear level. Applies to all tires, regardless of type.
Prior to this, for 12 years or more, I always used Toyo GSI5, which I use all year. (They did upgrade/update each year or so, noticeably better each year) They were very great tires and lasted 60 to 80k, but a bit noisy summer time/dry roads. Which is why I decided to try these KO2, and it the first year, so with only about 10k, it too early to declare it a winner, but so far so good.
Weather is too changing here, (Get lots of warm Chinook Winds) so to have studs, I prefer to not use. I had them many years ago, but stop when it was banned in the province that I lived in. I think, Alberta will not bother you with them. Red neck country, we tend to use rocks instead of sand for sanding here. You can tell by the windshield, only province where you don't get warned or ticketed. lol
If I do find anything negative, I will inform this thread. So far, I haven't found anything negative and I'm expecting the performance that I got from my Toyo GSI5, where I have gone through 5 sets in 12 years (Went through CRV, Camry Hybrid, Odyssey. I do lot of mileage each year) to be met by KO2, if not better. I never used the GSI5 on a truck, so I have to keep that in mind.
