Tire, life.
 

Well just seeking to see, what tires people use and about, how many kilometers they got out of them 210/70r14 nitto terra grapplers purchased them 14/30's stand about 50% according to web page. what tire size you got? drive a lot off/on road?

What is important is that you should determine the manufactured date of a certain tire and should be consumed within 6 years upon manufactured.

Thanks for sharing information about tire life !
