I believe this is a version of siping - you should be fine. Might improve your trailer handlingGreat Googley Moogley!!!!!

Yes, those cuts in the treads on those fairly new tires line up exactly with the fenders...
I've had a LOT more weight on this trailer in the past (taller stacks of oak), don't ever recall seeing this.
