No more than what's listed as max recommended pressure on the tire sidewall. Apart from that you're free to try out what feels best when riding. Low pressure will increase the risk of bottoming out the tire(the rim striking the surface) which is an almost certain way of getting a snakebite AKA pinch flat.
Imagine your leg was a flat inner tube. Imagine pumping air into that inner tube which slowly begins to fill up. With just enough air you can bend the tube in half with relative ease. Now Consider the joint where the inner tube bends as your knee joint - pumping too much air into the inner tube makes it difficult to bend the tube in half. In other words a sprained knee feels like your knee joint is filled with too much air making it difficult to achieve a full range of motion.
To hold air.

It depends on ocean currents, air pressure, and weather. But 40 miles from Cuba to Miami on inner tube could take a day or two.
One way would be to fill the tube with air, and then hold it under water and look for bubbles. Wherever the bubbles are originating from on the tube is the source of the leak.
Inspect the inner tube, if puncture is small, use a repair kit and put air in, if it is large (unlikely) you need a new tube
It is located on the top of the air intake tube. This tube comes from the left (driver side) inner fender area & connects to the bottom half of the air cleaner box (where the air filter is)
The valve is a one-way system. It allows the cyclist to inflate the inner tube with a pump - while preventing air from escaping.
Bicycle tire inner tubes tend to have 10-15 psi of air pressure, so the air tends to be the same temperature as the ambient air temperature.
there should be an air canister, with a tube leading into the throttle body. u can remove this tube and unscrew the bolt to get the old air filter out.
The air inside your inner ear has to be the same pressure as the cabin air... When the plane is going up, the cabin air pressure is dropping. The higher pressure air inside your inner ear leaks out thru your eustachian tube. It is easy for the air inside the inner ear to leak out, however, when the plane is coming back down, the cabin pressure is higher than the pressure in your inner ear... that higher external pressure presses against the soft tissues in your head and makes it harder for the air to flow back thru the eustachian tube into your inner ears. The long exposure to the dry cabin air also contributes to the problem. The easiest remedy is to bring gum. Chew the gum the entire time the plane is descending. This works your jaw and the tissues around your eustachian tube to work the air back into your inner ear. Also- drink plenty of fluids to stay hydrated.
