I have a Checkpoint ALR3 Gen3 with a little over 2000 miles on it running on the stock Bontrager Girona Pro tubeless tires. I noticed tonight that I had a wet spot on the rear and upon further inspection found a small gash on it. (First photo.) Then I realized compared to my front tire (second photo) I have no tread left on the center part. It seems to be holding pressure but I’ll recheck it in the morning. I’m guessing at the bare minimum I need a new rear tire but should probably just replace both.
Aside from the gash I’m also guessing based on the wear patterns I’ve got the pressure wrong on the rear at least. I’ve been running 45psi in both since I bought it in March. (Which the LBS told me to use and the Bike Tire Calc app confirmed.) But any better suggestions on that? I’m only really riding paved neighborhood roads and bike paths with it.

Back wears out faster and I usually go through two rears per front. Some will say to put the new tire on the front and put your front on the back – it helps ti gave the better tread on front as a rear flat is easier / safer to deal with.
