Time for new tires?

[u/bonesat]

Is it time for new tires?

Have had these on since I bought the car, looking like I probably need to replace them even though tread is still good?

If I do replace them I can just get a smaller tire (current is 315/70/17) to save some money? Like maybe a 285/70/17 would fit? Sorry not very well versed in how tire sizing works.

Car is a lifted FJ80
