Pour a dilute soap solution on the stem before beginning to determine if it's the source of the leak, and repair any leaks by replacing the valve stem core. The process takes about 10 minutes and requires a valve stem tool and replacement core.Continue Reading
The caps protect the stem from mud and dirt. Unscrew the cap, and save it to reinstall later.
Pour a small amount of dilute soapy water on the end of the valve stem. If it's leaking it should form bubbles.
Use the tapered end of the valve stem tool to remove any debris from the end of the valve stem so that they don't drop into the tire when you remove the stem insert.
Use the tool to unscrew the insert and remove it from the valve stem. Air leaks out of the stem when you loosen the insert. Work quickly so that the seal between the tire does not break.
Use the tool to screw the replacement part into the valve stem. Make sure it's snug, but do not over-tighten.
Use an air compressor to inflate the tire. Use a pressure gauge to check the pressure and ensure it's within the manufacturer's recommended range. Test for leaks.
Screw the cap back on the valve stem to provide protection as you drive the vehicle.
Drivers check tire pressure by removing the valve cap and pressing the tire pressure gauge onto the valve stem. A hiss sound occurs but stops when the gauge is pressed down hard enough. The user reads the marks on the bar that pops out or reads the digital display.Full Answer >
To check tire pressure, remove the valve cap, hold the tire gauge over the tire stem, and press down with a firm, swift movement. Read the marking on the bar that pops out if using a standard gauge or the reading on the screen for a digital gauge.Full Answer >
At their core, tire load indexes and speed ratings work under the same principle: the higher the number/letter, the higher the load the tire can carry, and the higher the speed it can reach, save for an H, which appears in the middle the speed chart.Full Answer >
The solution is intended for tires with minimal damage, such as small puncture wounds or slow leaks, and works for that level of damage. Larger or more complex areas of damage are unlikely to be effectively remedied.Full Answer >
