- Add air in short bursts, checking pressure between each
- Stop when you reach the recommended pressure
- Replace the valve cap
Many gas stations offer free air pumps, or you can invest in a portable air compressor for convenience.
Releasing Excess Air
If your tires are overinflated:
- Press the small pin in the center of the valve stem
- Let out small amounts of air at a time
- Recheck the pressure frequently
- Stop when you reach the correct pressure
It’s better to release air in small amounts to avoid underinflation.
Seasonal Pressure Adjustments
Tire pressure fluctuates with temperature changes. For every 10°F change in temperature, tire pressure can change by about 1 PSI. In colder months, you might need to add a bit more air to your tires.
Common BMW X5 Tire Pressure Issues
Even with regular maintenance, you might encounter some tire pressure issues. Here are some common problems and how to address them:
Underinflation Problems
Underinflated tires can lead to:
