2.3 bar is not 23 psi. On this Cooper SD 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 Cooper SD Countryman placard versus sidewall

If the MINI sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

Estimated pressure by tyre size (225/40R18 and others)

225/40R18 is the first planning size here. 225/50R17 is usually the plus-size or LT step. Keep load index at or above original equipment.

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 Cooper SD Countryman

  1. Measure before the school run, not after the M25.
  2. Write LF / RF / RR / RL. Do not keep Cooper SD 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 Cooper SD Countryman.

MINI notes

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

Spare and inflator kit

A matching full-size spare on the MINI Cooper SD 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.

If the MINI sticker and this page disagree, the sticker wins.

Questions about this Cooper SD Countryman

How often should I check a Cooper SD Countryman?

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

Front versus rear on the MINI Cooper SD 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 is that in bar and kPa for the Cooper SD Countryman?

Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.

When does TPMS warn on a MINI Cooper SD Countryman?

Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.

What PSI if I plus-size toward 225/50R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/40R18, 205/60R16 and 225/50R17 as a planning band.
