Your tire could be losing air due to a faulty valve, a nail or other puncture, or because some joker is letting out the air.
Take the cap off the valve stem. Put a little saliva on the tip of a finger. Cover the tip of the valve stem with that. If it blows a bubble, that is your problem.
Next look at the tire and feel it. You are looking and feeling for the head of a nail. (If there are sharp rocks or broken pieces of glass in the area, you only want to look! You do not want to cut your hand.) You may find it. Then you will have found the problem!
Actually, you will have to take it to a shop to have it fixed. You could have saved yourself all that trouble because they do that anyway.

Can a tire loose air pressure within three days?
Yes. And it can loose it in a lot less time if there is a nail or other fastener has gone through it. Some metal "spears" can let the air out of a tire in only a few minutes.
Which one would be the heavier tire air tire or punctured tire?
There would be no detectable difference.
What would you put in your bicycle tire to inflate it?
air with an air pump
Is there any need of air or water medium for tubeless tire?
Well obviously there is a need for air, how else would you inflate the tire .
what is the basic function of an air valve?
The basic function of an air valve is to control the release of air that is under pressure. Common places where an air valve would be used is on an inflatable tire. It is used to add more tire pressure to the tire.
How do you remove front tire from a 1995 dodge caravan?
First, break the lugnuts loose with the lugwrench while the tire is still on the ground. Then jack up the vehicle near the tire that needs to be removed. with the tire in the air. Finish taking off the lugnuts. Tire should come off.
If you stop a tire quickly - dead stop - would the air inside the tire continue to go round from inertia?
The air inside the tire would continue to move the same as the water in a glass will still move after you stop stirring it.
Why does tire pressure reduce?
Tire Pressure usually goes down when the temperature gets cold outside, or the vehicle has sat for a while. Because tires are made of rubber they expand and contract with the temperature difference. Another thing that causes tires to loose pressure is the air inside them. Because warm air rises, and cold air sinks. When the tires are contracting from the cold, the air inside the tire sinks out through the contracted openings around the rim and valve stem, just enough to loose some pressure.
Can you use a tire pump to air brush?
Probably not. It's unlikely that a tire pump (particularly if it's a manual one) would give enough air flow for air brushing.
Does a car tire weigh more with air or the same when its flat and tire is on a rim?
The chemical signature for air is H20, or 2 parts Hydrogen and 1 part Oxygen. As each of these elements has mass, even in a gaseous state, the short answer is that air weighs 0.070 lbs oer cubic foot. So at one atmosphere of 14.7 PSI (that is the pressure of the air around us) when the tire is flat, if you knew the volume of the tire, you could compute the weight of the air in the tire. Now, if the tire were inflated to 26 PSI, it would be at 1.77 atmosphere, so the weight of the air in the tire when inflated would more than when it is flat. No, H2O is the chemical signature for WATER. Otherwise the answer would be correct.
When would the air pressure inside a bicycle tire be lowest?
When you are not sitting on it.
What happens to the air pressure inside a tire when it is warmed?
The warming air would expand and the tyre pressure would go up.
