Mitsuoka Rock Star tyre pressure in kPa

Drivetrain: front-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

kPa

231 / 231

2.31 / 2.31 bar · 32-35 / 32-35 psi

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

Kilopascals show up on some Asian stickers and ISO sheets. 231 kPa front and 231 kPa rear is the Mitsuoka Rock Star midpoint (100 kPa = 1 bar). TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

kPa, bar and PSI

kPa-led conversions. 220 kPa is 2.2 bar and about 32 psi — handy if this Rock Star sticker uses SI units.

kPa	Bar	PSI
207	2.07	30
221	2.21	32
228	2.28	33
231	2.31	33.5
241	2.41	35
248	2.48	36
262	2.62	38
276	2.76	40

Estimated pressure by tyre size (205/55R16 and others)

If your Mitsuoka Rock Star no longer wears the OEM diameter, start at the row nearest 205/55R16 or 215/50R17 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
195/65R15	34	34	2.34	2.34	234	234	Very common compact
225/45R17	35	35	2.41	2.41	241	241	Sport 17-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch

Mitsuoka Rock Star placard versus sidewall

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

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Rock Star.

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

How to set the Rock Star

Park the Mitsuoka Rock Star for at least three hours (cold tyres).
Use a calibrated gauge, not the only meter on a forecourt hose.
Set the placard for that axle — about 32-35 psi / 2.2-2.4 bar front and 32-35 psi / 2.2-2.4 bar rear on this catalogue row.
Recheck all four. A 2 psi miss on a front-wheel drive Rock Star is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

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	37 psi / 2.55 bar

Mitsuoka notes

No special Mitsuoka exception: the Rock Star uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.

Spare and inflator kit

A matching full-size spare on the Mitsuoka Rock Star 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 Rock Star than nitrogen upsells.

Questions about this Rock Star

Front versus rear on the Mitsuoka Rock Star?

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.

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.

Is the sidewall number correct on a Mitsuoka Rock Star?

No. Sidewall PSI is a maximum. The Rock Star placard is the operating target, near 32-35/32-35 psi.

When does TPMS warn on a Mitsuoka Rock Star?

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

What is that in bar and kPa for the Rock Star?

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