The incisions open onto the contact surface of the tread, are essentially parallel to one another, and having a mean inclination alpha different from zero relative to the direction perpendicular to the rolling surface (S) of the tread. The tread is characterized in that, when viewed in a section plane perpendicular to the rotational axis of the tire, each incision in a given rib, relative to a perpendicular to the contact surface of the rib at the point where the incision intersects the surface, has an inclination which varies through the thickness of the tread, each incision being inclined at an angle beta1 relative to said perpendicular at its point of intersection with the rolling surface when new, the angle beta1 being larger than the angle alpha, and at an angle beta2 at the point of the incision furthest inside the tread, the angle beta2 being smaller than the angle alpha. The point of the incision furthest inside the tread being located, relative to said perpendicular, such that it is ahead of the point of the incision located on the contact surface of the rib.

An enclosure providing a workspace for astronauts, deep-sea divers, etc. wearing pressurized suits includes a housing providing a substantially-closed chamber, a port providing access to the chamber, and a connector circumscribing the port. The enclosure's connector is configured to mate with, and form an airtight seal with, a complementary connector of the suit to close the chamber. A pressure control system may be provided to pressurize and depressurize the chamber. After connecting the enclosure to the suit, the closed chamber may be pressurized to balance pressures internal and external to the suit to facilitate manual operations. Any mated connectors of suit portions internal to the enclosure may be decoupled to expose a human limb, etc., and yet the pressure in the chamber may be maintained. The suit may include a limb-engaging seal resisting intermixing of chamber gases with suit gases while matable connectors of the suit are decoupled.
