5.4Rotation of Tires and Wheels:

On the Grid Approach Lane, a Grid vehicle's tires and wheels, which are situated vertically for normal roadway operation, may rotate down and inward to a horizontal position once a Grid vehicle is established on the Grid Rail. Thereafter, the vehicle's tires will contact the inside of the Grid Rail I Beam at a predetermined pressure (approximately .3 times gravity or "g") supplying sufficient traction for Grid vehicles to reach their optimal velocity.
