Owner's manuals usually recommend to check the tires' air pressure weekly.
air pressure
No -- Keep the same recommended air pressure in your tires at all times, but check and add air when the tires are cool and have not been running. Use a tire pressure gauge.
The recommended air pressure for mountain bike tires is typically between 25-35 psi to ensure optimal performance and traction on various terrains. Adjusting the air pressure within this range can help improve grip and control while riding.
Low pressure.
If air is escaping from your tires then you have a leak. Repair the leak and no more air will escape. This is not to say you never have to check the air pressure. Tires are made from a porous material and as such will loose a very small amount of air even under the best of circumstances. Check the pressure on a regular basis.

Proper air pressure in bike tires is crucial for optimal performance and safety. It affects the bike's handling, speed, and ability to grip the road. Incorrect air pressure can lead to increased rolling resistance, decreased control, and a higher risk of punctures or blowouts. Regularly checking and maintaining the correct air pressure is essential for a smooth and safe ride.
Air expands when heated so therefor increases the preasure
It depends on the tire type and the load of the vehicle. Tire pressure is the amount of air in a tire that inflates the tire to the maker's specifications. For specific tire pressure on a specific vehicle, please look at the sidewall area, as most tires display the recommended pressure according to maximum load.
Even though all four tires have the correct tire pressure, the light will stay on if the pressure in the spare tire is incorrect. This is because of a sensor in the tires.
The air pressure inflates the tire and holds it away from the rim.
