Which requirement related to tires is essential to ensure proper vehicle adherence to the road surface?

Question

DentroTest · Accepted Answer

Vehicle adherence depends almost exclusively on the condition of the tires, as they are the only point of contact with the ground. According to current regulations, to drive safely and ensure water evacuation (preventing aquaplaning), the tread depth of the main grooves must be at least 1.6 mm. The other options are dangerous: excessive air pressure reduces the contact patch, thereby decreasing grip, and mixing different types of tires on the same axle or between axles alters the car's stability and handling.
