2.3 bar is not 23 psi. On this John Cooper Works Countryman 2.2-2.4 bar converts to about 32-35 psi. Use the table, not a guess. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

MINI John Cooper Works Countryman placard versus sidewall

The tyre-information placard on a MINI John Cooper Works Countryman sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

Estimated pressure by tyre size (225/50R17 and others)

If your MINI John Cooper Works Countryman no longer wears the OEM diameter, start at the row nearest 225/50R17 or 185/65R15 and confirm with the tyre maker’s load table.

Load notes

Load moves the rear of a passenger car first. If the factory placard already has a “laden” column, use that instead of these sketches.

How to set the John Cooper Works Countryman

  1. Measure before the school run, not after the M25.
  2. Write LF / RF / RR / RL. Do not keep John Cooper Works Countryman numbers in your head.
  3. Add air in short bursts toward 34 psi (2.31 bar) front and 34 psi rear.
  4. If one corner is 4 psi down, hunt for a nail before you blame the weather.
  5. Log date, ambient temperature and the four readings.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this John Cooper Works Countryman.

MINI notes

MINI run-flats ride harshly if you overshoot. Stay in the printed band on this John Cooper Works Countryman.

Spare and inflator kit

A matching full-size spare on the MINI John Cooper Works Countryman usually follows the higher axle (often the rear, near 32-35 psi). A space-saver is commonly 60 psi / 4.1 bar — read that tyre’s own sidewall. An inflator kit is not a spare; check the sealant date.

Keep the MINI John Cooper Works Countryman on the printed band; use 225/50R17 and 215/55R16 only as a map for non-OEM wheels.

Questions about this John Cooper Works Countryman

Front versus rear on the MINI John Cooper Works Countryman?

This row is 32-35 F / 32-35 R. Even when they match, a laden rear can justify a higher number if the sticker prints one.

What tyre pressure should a MINI John Cooper Works Countryman use?

Catalogue reference is 32-35 psi front and 32-35 psi rear (2.2-2.4 / 2.2-2.4 bar), cold. Confirm on the door-pillar placard.

What PSI if I plus-size toward 215/55R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/50R17, 185/65R15 and 215/55R16 as a planning band.

How often should I check a John Cooper Works Countryman?

Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.

Is the sidewall number correct on a MINI John Cooper Works Countryman?

No. Sidewall PSI is a maximum. The John Cooper Works Countryman placard is the operating target, near 32-35/32-35 psi.
