Two things effect the life of a tire, wear and age.

10 years is considered the max life of a tire regardless of milage and naturally the amount of tread is the second defining charteristic.

I see nothing on those pictures, they still have good tread, and are well under the 10 years. Keep using them!

Then put the old ones on CL and ask $125 for the 4 of them.

That is always a wise decision, you decide they are not suitable so your going to sell them to someone who probably knows less. Hopefully not used by their wife/daughter!
