Can you replace valve stem without removing tire?

What causes a valve stem to leak?
Wear and tear is the main cause of a leaking valve. It has a mechanism consisting of a spring-mounted valve that closes tightly with the air pressure inside the tire. Over time, the stem valve may become brittle and cracked, which may increase the risk of air leaking through it.
Can you drive with a leaky valve stem?
We have good news for you! You CAN continue driving! The purpose of the air valve cap is to keep dirt and debris out and to keep air inside in case the air valve ever does leak (you can find out if it is leaking by spraying some Windex on the valve and see if it bubbles).
How do you tighten a valve stem?
How to Tighten a Valve Stem Turn the valve stem clockwise as far as you can with your fingers. Hold the valve stem while you turn the valve tool clockwise onto the top of the valve stem. This action will attach the valve tool to the valve stem. Continue turning the valve tool clockwise until the stem is tight.

How do you know if your valve stem is leaking?

How do you know if you have a bad valve stem?
If a valve is bad you’ll have a constant and very slow leak through the base or the valve body. The other possibility is that the mounting surface of the wheel where the bead of the tire seats has become damaged by corrosion or dented from hitting a pothole.
Do tires leak air without the cap?
While a missing valve stem cap may seem harmless, it can lead to loss of air pressure. Without a cap, dirt and debris will enter the valve stem where it can break through the seal. When this occurs, air will leak out of the tire through the valve stem.
Are valve stem 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. The loss of tire pressure also causes your vehicle to burn more gas.
How long does it take for a slow leak to flatten a tire?
Most regular cars’ handling will start to feel “squishy” when a tire gets down below 20 psi. If it drops under 15 or 10 you quickly start to risk sidewall damage and catastrophic failure. Some leaks will drain a tire in a matter of minutes, others in a matter of weeks.
How tight should a tire valve stem be?
One detail is knowing how tight is enough for your valve cores. Over-tight can cause the small gasket to deform and even split and under-tight will result in a slow leak. (This was 3/4 turn after the leak stopped.) So, I would suggest that you can simply tighten a core until the leak stops then rotate 1/2 turn more.
How tight should valve stems be?
With my Prestas I tighten the nut barely finger-tight before inflation, then tighten again after inflating, as tight as I can with my fingers. You don’t want it so tight you won’t be able to remove it if you have to do a roadside repair (without a pair of pliers), but you want it to stay on and not rattle.
