The tire width is related to friction. The wider the tire, the greater the friction.

  The force that prevent the relative motion of the object (or relative motion tendency) is called friction. The direction of friction is opposite to the direction of relative motion (or relative motion) of the object. Methods for increasing the friction include increasing the pressure, increasing the roughness of the contact surface, and the magnitude of the pressure.

  The methods for reducing harmful friction are as follows: 1.reducing the pressure 2. to smooth the object and the contact surface 3.separating the object from the contact surface . The friction of classical physics is applied to an indeformable object, and the rubber of the tire is deformed and thus this theory does not apply. In reality, a wider tire can provide greater "static friction", or grip.
