Good asking price for used tires

[Lars]

Hello everyone, got a question.
I have 4 used tires I had taken off in favour of new ones. I still have the old to sell and wondered what a fair asking price would be. I will be listing them on my local Craigslist market.
A little tire info here...

(2 tires) Fuzion HRi
P185/60R14 82H
40% of treadware left

(2 tires) Kuhmo Solice HP4
P185/60R14 82H
30% of treadware left.
None of these tires leaked air pressure when they were taken off.

Is $60 for the set asking too much? Or is that price too low?
Thanks for any input.
