I guess judging by the reaction of my passengers, mine doesn't work.

 

A. I rotate my spare in so everything is the same.

B. I picked up a nail last week. I didn't need the spare because of on-board air. I just had to top off and get to Big-O to have it pulled and plugged. BUT a spare is 1) in most states legally required and 2) there for when it's needed. I go by the thought - better to have it and not need it than to need it and not have it.

 

How the vents/exhausters works,when is in cargo some trunk?

 

Without a vent in my tailgate I'd explode

 

Think of the air as a solid occupying all of the otherwise unoccupied space in the Jeep. When you close the door and push more air in, with the arc of the door, the air inside needs to go somewhere. Just like water, it will flow in the direction of least resistance - which in this case is any crack or opening like the vent.

 

I´ll try cover it tomorow

 

Have somebody shut a door while your jeep is sealed ... you see the flaps on the vent open and let the air out ...

 

when i go off roading ill just throw my spare in the back of my jeep.....i like the look without it.
