Knobby Tires
by admin on Sep.17, 2008, under Glossary
Unlike slick tires, knobby tires have a lot of tread pattern, with knobs or bumps of various shapes, designed to dig into soft surfaces for better traction. Knobby tires get better traction on soft surfaces such as mud, gravel, snow, and dirt, compared with smooth treaded tires.
Knobby tires perform extremely bad on paved surfaces. The knobs greatly increase rolling resistance, and create annoying vibrations. They also corner badly on pavement, due to squirm.
