The amount of gripping between the tires and the road depends on the contact force between them that is friction. The friction in turn depends on the magnitude of the normal force generated from the ground.
In case the car is on the horizontal level road, the magnitude of the normal force is proportional to the magnitude of its weight. However on an inclined slope, the normal force has a horizontal component in addition to the vertical, which does not contribute in increasing the friction.
Therefore the frictional force between the tires and the road is more on a level road than on an inclined slope, thereby allowing car to grip better.

The friction force between tires and road on the level road is more than when going uphill or down hill.
