Skuddbutt, commonly referred to as tire mark, is a term used to describe a spot left behind by a motorcycle during skidding. Skuddderbutts can be seen on streets in the midst of slick weather, such as heavy rain or snow. These marks function as indicators of possible sliding or lack of traction and should be handled carefully. Drivers are cautioned to decrease their speed and keep up a safe distance from skudder bottoms to avoid any potential collisions. Stay safe on the roads!
