Premature tire wear?

Pressures and camber seem right on from this side of the keyboard. But it looks like they are rolling over. I would say more of a rolling over problem more than camber just by how rounded the outside edge is.

First suggestion is try the old white shoe polish trick. I would make a guess that 45/45 psi hot is as high as you would want to go on a street tire (36 to 38 hot on a more true racing tire, not too sure where the Nittos are). If it feels like it is “skating” then it’s too high.

On the driver side of things looks like they are pushing, how much steering angle do you put in when you drive. The better the tire, the less angle is required to make maximum grip. Even on the subconscious level try driving with just you thumb and fore finger pinching the wheel instead of a death grip.

Looking at the wear bars you could run more camber but that is not accounting for the 1.5" edge that you originally mentioned.

How’s the toe, could be toe in…

As for those tire. Just get them dismounted and flip them. Even if the say “mount this side out” “this direction only” they will be fine to get a couple more events out of.
