The quickest way is to use the Tire Pressure Monitoring System (TPMS) and its readouts on the instrument cluster or information display. If the system isn’t clear, you can verify with a tire gauge against the door jamb sticker’s recommended pressure.
Understanding the TPMS readout
The CR‑V 2019 uses a TPMS to alert you when a tire is under-inflated. When a tire drops below the recommended pressure, a warning light typically lights up on the dash. Many models also offer a per-tire pressure readout on the driver information display, showing each tire’s current psi and helping you identify the low tire without guessing.
What the readout shows
On the information display, you’ll usually see four values labeled for the tires (for example, FL/FR/RL/RR or LF/LF/LR/RR). Each value indicates the current cold pressure for that tire. Use this readout to identify which tire is lowest relative to the others and to the recommended level.
To make the most of the readout, follow the steps below before relying on the gauge or inflating.
Using the TPMS readout is the fastest way to spot a low tire, but you should verify with a manual measurement if you’re unsure or the readout isn’t clearly indicating a tire.
Manual verification: checking each tire with a gauge
If you prefer or the display doesn’t clearly identify the low tire, manually check all four tires with a tire pressure gauge. Here’s how:
- Locate the recommended cold tire pressure on the driver’s side door jamb sticker or in the owner’s manual. Note the value for the front and rear tires (these may be the same or different by axle).
- With tires cold, remove the valve cap and press a tire pressure gauge onto the valve stem to get a reading for each tire. Record the psi for all four tires.
- Identify the tire with the lowest pressure and compare it to the recommended value. If a tire is below the spec, that is your low tire.
- Inflate the low tire to the recommended pressure using a reliable air source. Recheck the pressure to ensure accuracy.
- Repeat for the other tires if needed and recheck all four after inflation to ensure even and correct pressure.
After inflating, the TPMS should recalibrate as you drive. If the warning light stays on, or a tire continues to lose air, there may be a slow leak or a puncture that needs professional attention.
What to do after inflating
Drive a short distance (a few miles) and recheck the tire pressures. The TPMS light should turn off once the system recognizes all tires are at or above the recommended pressure. If it remains illuminated, consult the owner’s manual or a Honda service professional to diagnose a potential leak or sensor issue.
Safety tips and maintenance
Always check tires when cold and keep a reliable gauge in your vehicle or toolbox. Regularly inspect tires for damage, wear, and punctures, and rotate them as recommended by Honda to promote even wear and reliable TPMS readings.
Summary
On a 2019 Honda CR‑V, low tires are signaled by the TPMS warning light and, in many trims, a per-tire pressure readout on the instrument cluster or infotainment display. Use the readout to quickly identify which tire is lowest, or verify with a manual tire pressure gauge against the door jamb’s recommended pressure. Inflate to spec, recheck, and monitor the system to maintain safety and optimal performance.
