A quick check can usually reveal the low tire: if your Civic has a Tire Pressure Monitoring System (TPMS) with a readout, you’ll see which wheel is underinflated. If not, you can confirm with a standard tire-pressure gauge by testing each tire against the factory-recommended pressure.
Understanding the TPMS readout on the 2017 Civic
The 2017 Honda Civic can warn you about underinflated tires with a TPMS alert, and many trims provide a per-tire pressure readout in the instrument cluster or multi-information display (MID). This lets you identify the specific tire that’s below the target pressure without guessing.
To use the on-board readout, follow these steps:
- Turn the ignition to the RUN position (the engine can be off) and access the Vehicle Information or Tire Pressure screen using the steering-wheel thumb controls.
- Look for a display that shows each tire’s current PSI, often labeled LF (left front), RF (right front), LR (left rear), and RR (right rear). The tire with the lowest pressure is the one that needs air, compared to the recommended value printed on the driver’s door jamb placard.
- Note that the readout reflects cold pressure; if you’ve driven recently, you may want to recheck after the tires have cooled to get an accurate reading.
Using the per-tire readout is the fastest way to pinpoint the low tire on most 2017 Civics that feature this display capability. After identifying the tire, inflate it to the recommended cold pressure and recheck all four tires for consistency.
Manual method: checking tire pressures with a gauge
If your vehicle’s readout doesn’t show per-tire data, or you want to verify what the display says, use a handheld tire-pressure gauge to measure each tire’s PSI. This is a reliable, model-agnostic way to identify the underinflated tire.
Before you begin the manual check, prepare the following:
- A reliable tire-pressure gauge and access to the door-jamb placard for the recommended cold PSI.
- A level, safe surface to park on and a few minutes to measure all four tires (and the spare, if you’re inspecting it).
Then perform these steps:
- Park on a level surface and ensure tires are cold (ideally no driving for at least three hours). Remove the valve-cap from each tire.
- Press the gauge onto the valve stem firmly and note the reading for each tire. Record readings for LF, RF, LR, and RR, if your gauge distinguishes positions.
- Compare each tire’s PSI to the recommended cold pressure listed on the door jamb placard. The tire with the lowest reading—or any tire significantly below the recommended value—is the low tire.
- If a tire is below spec, inflate it to the recommended pressure, then recheck all tires to confirm even inflation.
Manual checking gives you an exact measure of each tire’s pressure and is useful anytime the on-board display isn’t showing per-tire data or you suspect a reading error.
What to do once you’ve identified the low tire
After identifying the low tire, take these steps to stay safe and avoid damaging the wheel or tire:
- Inflate the tire to the manufacturer-recommended cold pressure listed on the placard. Recheck with a gauge to ensure accuracy.
- Inspect the tire for nails, screws, sidewall damage, or other punctures. If you find damage, consider repair or replacement as appropriate.
- Check the spare tire as well; if you’re using a temporary spare, drive cautiously and replace it with a proper tire as soon as possible.
- If a tire continues to lose pressure after inflation, have it inspected by a professional — there may be a puncture or a faulty TPMS sensor.
Always address a low tire promptly. Driving on underinflated tires can reduce fuel efficiency, handling, and tire life, and can increase the risk of a blowout.
Key details to know for the 2017 Civic
Use the door-jamb placard for your exact cold-pressure targets, as recommended pressures vary by tire size and trim. If your Civic is equipped with a per-tire pressure readout, you’ll typically see LF, RF, LR, and RR pressures displayed, helping you quickly identify the low one. If you don’t see per-tire data, rely on a reliable gauge and the placard to determine which tire needs air.
In all cases, maintain proper tire pressure across all four tires and the spare, rotate tires as recommended by Honda, and check pressures at least monthly or whenever you notice handling changes or a TPMS warning.
Summary
To determine which tire is low on a 2017 Honda Civic, use the on-board Tire Pressure Monitoring System readout when available, which often shows per-tire PSI (LF, RF, LR, RR). If the display isn’t available or you want confirmation, check each tire with a trusted gauge and compare to the door-jamb placard. Inflate the low tire to the recommended cold pressure, inspect for damage, and recheck all tires for consistent inflation. Regular maintenance of tire pressure enhances safety, efficiency, and tire longevity.
