Didn't find much info in my quick 10 minute search across the web. I can only find they were for a race series called Jeepspeed. I'd like to know if they will be available in a normal street version. Like 6 or 8 ply instead of 3-ply.

 

Those are probably the AT1's. I'm used to seeing the General Grabber AT2 tires.
I could be wrong, but thats what I think that tire is.
