Tire question





I came across tires (goodyear eagle f1 gs ) for both the front and backs.
Now l realize that they are no longer made but they are supposed to have a depth of 7/32's and only driven 2000 miles which l question if that's possible but l can be way off!
Now l realize that each tire has a code which will tell me when the tire was made but l can't find the thread. Any help
Also l am aware that l tire can have a lot of thread but dried out. Is this just a feel thing or is there a better way to find check it out.
I hope to pay no more then $400, if it's more then l will buy new tires when l need them.
Thanks
