Step-by-step instructions

Follow these steps

Follow the written instructions in order; illustrations are optional, not a requirement for a complete guide. If a component or label looks different on your car, stop and check your own manual.

  1. Step 1 of 7

    Confirm whether the car uses the original turbo or non-turbo package

    Review the N-WGN JH3 trim and tyre size actually fitted. Honda's 2020 manual separately labels 155/65R14 75S for non-turbo and 165/55R15 75V for turbo equipment.

    Check before moving on

    Trim, sidewall and placard agree.

    All steps ↑
  2. Step 2 of 7

    Read the actual cold-pressure placard

    Check the manufacturer's label and compare it with Honda's 2020 table. The label on the actual car takes precedence if equipment or year differs.

    Check before moving on

    Factory label is legible.

    All steps ↑
  3. Step 3 of 7

    Choose the correct figures for each axle

    Honda lists non-turbo 155/65R14: FRONT 240 kPa and REAR 230 kPa; turbo 165/55R15: FRONT 210 kPa and REAR 210 kPa. Do not treat these as interchangeable.

    Check before moving on

    A single matching row is identified.

    All steps ↑
  4. Step 4 of 7

    Take four readings when tyres are cold

    Park safely before a drive or after cooling, remove caps and use the gauge to read each tyre. Repeat any unstable reading to rule out a bad seal.

    Check before moving on

    Four repeatable gauge values recorded.

    All steps ↑
  5. Step 5 of 7

    Adjust carefully to placard values

    Add air or release it gradually, rechecking until each tyre matches the confirmed front/rear cold value. Never inflate to a sidewall's maximum just because it is printed on the tyre.

    Check before moving on

    Tyres match vehicle placard.

    All steps ↑
  6. Step 6 of 7

    Inspect and restore valve caps

    Look for cuts, bulges and uneven wear; secure all caps. Take concerning defects to a tyre professional rather than assuming pressure adjustment corrects them.

    Check before moving on

    No visible hazard and caps refitted.

    All steps ↑
  7. Step 7 of 7

    Record the grade-specific results

    Save the date, size, trim and four readings. Check again periodically, before long drives and after changes to tyres or wheels.

    Check before moving on

    Inspection log completed.

Pressure is tyre/powertrain-package-specific. Never infer turbo settings merely from the JH3 chassis alone or transplant later N-WGN trim numbers without confirmation.
