I'm guessing you have never run the tires with the arrow going the
wrong way...  I'm sure that someone has done this piece of testing
already & I am wondering if anything 'bad' happened.

First hand info is good but a search engine can help too.

 >>A directional (also called a unidirectional) tread pattern is
designed to roll in only one direction and incorporates lateral
grooves on both sides of the tire's centerline. These point in the
same direction resuin v-shaped tread blocks. These grooves enhance
hydroplaning resistance at high speeds by pumping water more
efficiently through the tread pattern. <<
