psi front

2.31 bar · 231 kPa at the steering axle

32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa

A 3 psi miss on one front corner of this John Cooper Works Cabrio shows up as a wander before the TPMS lamp bothers you. Target 34 psi (2.31 bar) cold. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed MINI tyre.

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

225/50R17 is the first planning size here. 205/55R16 is usually the plus-size or LT step. Keep load index at or above original equipment.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
225/50R17	35	—	2.41	—	241	—	Touring 17-inch
225/40R18	36	—	2.48	—	248	—	Low-profile 18-inch
205/55R16	34	—	2.34	—	234	—	Typical mid-compact OEM
205/60R16	34	—	2.34	—	234	—	Taller 16-inch
195/65R15	34	—	2.34	—	234	—	Very common compact
185/65R15	33	—	2.28	—	228	—	Small / older car
245/40R18	36	—	2.48	—	248	—	Wide touring 18-inch
225/45R17	35	—	2.41	—	241	—	Sport 17-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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	36 psi / 2.48 bar

Steering feel on the John Cooper Works Cabrio lives on this axle. Do not drop front pressure to “soften” a plus-size 205/55R16; you will roll the sidewall in a roundabout.

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.

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

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.

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.

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.

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.

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

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