The rear of a passenger car takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the MINI John Cooper Works Cabrio is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include 245/40R18, 195/65R15 and 205/55R16 — interpolated from the catalogue midpoint, not a second factory sticker.

Estimated pressure by tyre size (245/40R18 and others)

Planning cold pressures for sizes often seen on a passenger car. This John Cooper Works Cabrio sample opens with 245/40R18, then 195/65R15 and 205/55R16.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
245/40R18	—	36	—	2.48	—	248	Wide touring 18-inch
195/65R15	—	34	—	2.34	—	234	Very common compact
205/55R16	—	34	—	2.34	—	234	Typical mid-compact OEM
215/50R17	—	35	—	2.41	—	241	Plus-size 17-inch
185/65R15	—	33	—	2.28	—	228	Small / older car
215/55R16	—	35	—	2.41	—	241	Slightly wider 16-inch
225/45R17	—	35	—	2.41	—	241	Sport 17-inch
225/40R18	—	36	—	2.48	—	248	Low-profile 18-inch

Pressure against load

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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	37 psi / 2.55 bar

A family passenger car with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this John Cooper Works Cabrio.

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.

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.

A cheap gauge and a monthly habit will do more for this John Cooper Works Cabrio than nitrogen upsells.
