How to check Subaru Ascent tire pressure?

To check Subaru Ascent tire pressure you will first need to determine its recommended tire pressure for the front and rear tires. Take off tire valve caps and use a tire pressure gauge to check tire inflation in every tire. Adjust Subaru Ascent tire pressure to its recommended levels. If overinflated, let some air out by pressing down the center plunger in the valve stem. If underinflated, add air with tire inflator. Recheck tire pressure to make sure all tires are properly inflated. Replace the valve stem caps. Make sure to check tire pressure when tires are "cold" and have not been driven for at least 3 hours. Remember that the front and rear tire pressures may differ.
