The tech-y lines look like a flourish added by a designer on a flashy concept rendering, but the grooves you see in the tire above are actually laser-etched. Tires have long been molded with grooves to channel rainwater outwards and help provide traction in adverse conditions, but the precision afforded by lasers should help engineers elevate this science to a new level. (It also doesn’t hurt that it looks cool as heck.)
