The furthermost tread on the tire is only riding half on and half off the road. I can tell because the tread is darker on the outside and lighter on the rest of the tire.

At what point will this affect my tire wear?
Well, you have way more weight on the middle of the tire so it is wearing out faster. Now tires these days last an incredibley long time, the hard slippery tires on my tracker have 65,000 miles on them and might have lost 1/3 of their original depth. Realistically I think tires should be replaced more often so "prematurely" wearing out the middle isn't a bad thing, it gives you an excuse to buy new tires again.
