What is the tire cap called?
Valve caps, often called dust caps or tire pressure caps, are the tiny plastic caps that screw onto tire valves.
Are tire caps necessary?
The tire valve stem cap is a critical component of the tire because it helps maintain tire pressure. Every tire has a Schrader valve; this valve is necessary to keep tires inflated. The tire valve cap acts as a cap for the Schrader valve. Without the tire cap, the Schrader valve is not completely leak proof.
What happens if I lose the cap to my tire?
A tire with its valve cap missing will not immediately lose air, but over time the slow air leak tire will lose pressure and require more fuel. You better check regularly and make sure all your valve caps are there and fixed correctly.
What do you call the thing that inflates tires?

Will a tire go flat without a cap?
When the cap is removed, the valve stem is exposed and can get clogged with road dirt, grease or ice. This can make inflating the tire difficult. A missing valve cap can also lead to a slow air leak over time, eventually resulting in a tire going flat.
Are tire caps universal?

How much PSI should my tires have?
32 to 35 psi
On newer cars, the recommended pressure is most commonly listed on a sticker INSIDE the driver’s door. If there’s no sticker on the door, you can usually find the specs in the owner’s manual. Most passenger cars will recommend 32 to 35 psi in the tires when they’re cold.
Do tires lose air when not driven?
You may find that your tyres lose pressure or start to slightly deflate over time while the car is immobile. This is because rubber is porous, and while it’s not enough to cause an issue normally, air molecules can make their way through the rubber slowly over a period of time.
Why do my tires keep losing air in the winter?
The main reason for this is the dropping temperatures, which cause the air to become denser and consequently lower the tire pressure. Couple that with tires naturally losing pressure over time, and fall and winter can be a busy time for pressure checks and adding a little air.
Can a tire go flat overnight?
A tire is liable to go flat overnight if it has been previously punctured during the day by any sharp object such as nails or broken bottles and the tire pressure is gradually lost during the night. When such happens, the reduction of air pressure is faster after it is parked at night.
