Check the Tire Pressure Again
If you’ve filled your Subaru’s tires with air and yet the tire pressure light is still on, there are a few reasons why this could be happening. One of the most common reasons is that the tire pressure simply wasn’t high enough to begin with. Make sure to double-check the recommended PSI for your specific vehicle model.
Another possibility is that there could be a slow leak in one or more of your tires. If that’s the case, you’ll want to bring your Subaru in for a professional inspection. It’s also possible that one of your tires has a bad sensor, which would require replacement.
Whatever the case, it’s always a good idea to regularly check your tire pressure to ensure your safety on the road. Don’t ignore the tire pressure light on your dashboard, as it’s a helpful reminder to keep your tires in tip-top shape and avoid potential accidents.
Use a Tire Pressure Gauge
Now that you’ve filled up your tires to the recommended pressure, don’t assume that they will stay that way forever. Temperature fluctuations and general wear and tear can cause the pressure to decrease over time, so it’s important to check it again regularly. To do this, you’ll need a tire pressure gauge.
These handy tools are inexpensive and easy to use. Simply remove the cap from the tire valve, insert the gauge, and take a reading. If the pressure is too low, you can add air back in until it reaches the recommended level.
This process might seem like a hassle, but it’s important for safety. Overinflated tires can lead to blowouts, while underinflated tires can reduce fuel economy and increase the risk of accidents. By keeping an eye on your tire pressure, you can ensure that you’re driving safely and efficiently.
Refer to the Owner’s Manual
When it comes to checking your car’s tire pressure, it’s always a good idea to refer to the owner’s manual. Every car is different, and the recommended tire pressure for your vehicle may not be the same as your friend’s or neighbour’s car. The owner’s manual will give you clear instructions on how to check the tire pressure and what the recommended pressure should be.
It’s important to check the tire pressure again after a few days to ensure it’s still at the correct level. Even if you think you’ve got it right the first time, a few pounds of pressure can make a big difference in how your car handles. By referring to the owner’s manual, you can be sure that you’re not over or underinflating your tires, which can cause uneven wear and tear on your tires, and affect your car’s fuel efficiency.
So, next time you’re in doubt, remember to check the owner’s manual for the correct tire pressure for your car.
Check the Valve Stem
If you find yourself wondering why your tire pressure light is still on even after filling your tires, you might want to check the valve stem. Sometimes, the valve stem can be the culprit when it comes to low tire pressure. A damaged or faulty valve stem can result in air leakage, causing your tires to lose pressure even if you recently filled them.
It’s a good idea to inspect the valve stem for any visible damage, such as cracks or tears. If it looks damaged, it’s best to replace it as soon as possible to avoid any further pressure loss. Be sure to also check the valve cap since it serves as a seal that prevents air from escaping.
If the cap is missing or not tightly secured, it could lead to air loss and trigger your tire pressure light. By keeping a close eye on your valve stem and cap, you can ensure that your tires remain properly pressurized, providing better performance and safety for your Subaru.
Look for Damage or Debris
When checking the valve stem of your vehicle, it’s important to inspect it thoroughly for any signs of damage or debris.

A damaged valve stem can cause a slow leak in your tire, leading to decreased fuel efficiency and potential safety hazards on the road.
Look for any bends, cracks, or rust on the stem, and remove any dust or debris that may be stuck to it. It’s also important to make sure the valve cap is securely in place, as it helps prevent air from escaping and dirt from entering. Taking the time to regularly inspect your valve stems can save you from unexpected flat tires and potentially dangerous driving conditions.
So, next time you’re checking your tires, don’t forget to take a close look at the valve stems!
Check the Valve Core
When you’re checking your bike’s tire pressure, it’s important to also check the valve stem. The valve stem is responsible for keeping the air in the tire, so it’s crucial to make sure it’s in good condition. Start by inspecting the valve stem for any cracks or damage.
If it looks fine, then you’ll want to check the valve core. The valve core is a small part that sits inside the valve stem and is responsible for controlling the airflow in and out of the tire. To check the valve core, first, remove the valve cap.
Then, use a valve core tool to unscrew the core from the valve stem. Inspect the core for any damage or wear and tear. If it looks fine, then you can go ahead and reinstall it.
Make sure that it’s tightened down securely to prevent any air from escaping. If you do find that the valve core is damaged or worn out, then it’s important to replace it right away. You can do this by purchasing a new valve core and using the valve core tool to remove the old one and install the new one.
Overall, checking the valve stem and valve core is an important part of maintaining your bike’s tire pressure. By keeping these components in good condition, you can help ensure that your tires stay properly inflated and your bike performs at its best.
