There are tires available for golf carts that will not leave black marks on solid surfaces. These tires are called gray or non-marking tires. Non-marking tires are used on golf carts and transport vehicles at airports, on pathways at golf courses and anywhere indoors where scuff marks would be unsightly. In addition to gray and non-marking pneumatic tires, all solid Amerityres are non-marking, and offer a variety of other benefits.
