That's absolutely normal if you aren't running any camber.

Normal if you are not running any - camber. I added -2 Front -1.6 Rear ill add camber or subtract depending on tire temps i will let you know.

camber and driving style

a lot of people use the tires to scrub of speed at entry rather than braking properly, it's a habit that's hard to break.

could also be incorrect tire pressures, i remember i burned through half of my RE11's in a single day when i first bought them, then went online and checked the pressures (should have done it sooner) and had them last the rest of the season.

It's pretty typical, even if you dial up the camber it can still happen. If they are symmetrical flip 'em on the wheels after a few autox events or between track days and you'll increase the tire life.

I'm also running AD08's - autocross only, no track days - and have seen the exact same thing. I'm running the max camber I can under SCCA stock rules at ~1.3 deg front and ~1 deg rear. The AD08's are symmetrical and I flipped mine at ~115 runs after starting them at full tread depth. At that point, I had basically erased the shoulder sipes on two of them and had the other two worn down pretty far.

I think this will be setup/surface/driver dependent, but I'm now at 36-38 F and 34-38 R, pavement/weather/co-driver dependent. At those pressures I'm still scrubbing the 'tips' off the 'triangles' that indicate how much the tire is rolling onto the sidewall, but I can live with the wear rate. YMMV
