The term "gravel" covers all surfaces that are not either asphalt or snow. Different types of terrain make specific demands on tyres which, in addition to resisting wear and outside aggression, are designed to cut through the loose top surface in search of firmer ground unterneath.
|GM and GL||Good traction and good transversal grip. Recommended for Autocross and Rallycross|
|GZG and GZS||Asymmetric L=left R=right|
fairly closed pattern for increased ground contact and optimized grip and traction.
|GZE||Asymmetric L=left R=right|
More open pattern for a better traction on slippery surfaces.
