European and UK handbooks usually quote bar. The MINI John Cooper Works Cabrio catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). Size estimates on this page include 195/65R15, 185/65R15 and 205/60R16 — interpolated from the catalogue midpoint, not a second factory sticker.

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.

Condition	Front (est.)	Rear (est.)
Driver only	34 psi / 2.34 bar	34 psi / 2.34 bar
Full occupancy	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	38 psi / 2.62 bar

How to set the John Cooper Works Cabrio

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

Ambient	Gauge (front mid)	Bar	kPa	Note
−5 °C (hard frost)	31 psi	2.14 bar	214 kPa	Gauge reads low; do not overfill once warm
0 °C	32 psi	2.21 bar	221 kPa	Gauge reads low; do not overfill once warm
8 °C (UK winter morning)	33 psi	2.28 bar	228 kPa	Gauge reads low; do not overfill once warm
20 °C (set cold here)	34 psi	2.34 bar	234 kPa	Baseline
30 °C	36 psi	2.48 bar	248 kPa	Do not bleed a hot tyre
38 °C (heatwave tarmac)	37 psi	2.55 bar	255 kPa	Do not bleed a hot tyre

MINI notes

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

Spare and inflator kit

A matching full-size spare on the MINI John Cooper Works Cabrio 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 John Cooper Works Cabrio

What PSI if I plus-size toward 205/60R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 195/65R15, 185/65R15 and 205/60R16 as a planning band.

How often should I check a John Cooper Works Cabrio?

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

What is that in bar and kPa for the John Cooper Works Cabrio?

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

Should I bleed pressure after a motorway run?

No. Heat raises the gauge. Set cold only. Bleeding a hot tyre leaves it low the next morning.

Front versus rear on the MINI John Cooper Works Cabrio?

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.
