I think I read on Falken's website they have a 75,000mile warranty.
Mine came on the car when purchased.
Do you happen to have the link to the document you reference?
I am not super experienced in reading these rating values so any additional documents would help.
Went searching for more posts and found that Stevedmc went 80,000miles on the Falkens if I recall from a previous post.
It looks like from your data above that the tread on the Kumho 51A is better.
So far the falkens are doing well for me cannot complain, they cost about the same as the Kumho's where I am.
