Infiniti EX30 bar chart (2.2-2.4 / 2.2-2.4)

Drivetrain: all-wheel drive
Body: SUV / crossover

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

European and UK handbooks usually quote bar. The Infiniti EX30 catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target. Keep side-to-side spread inside about 2 psi so the all-wheel drive hardware is not working on a radius mismatch.

Estimated pressure by tyre size (215/70R16 and others)

Planning cold pressures for sizes often seen on a SUV / crossover. This EX30 sample opens with 215/70R16, then 245/60R18 and 225/65R17.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/70R16	34	34	2.34	2.34	234	234	Compact crossover
245/60R18	36	37	2.48	2.55	248	255	Heavier CUV
225/65R17	35	35	2.41	2.41	241	241	Very common 17-inch
245/55R19	36	36	2.48	2.48	248	248	Low-profile 19-inch
235/60R18	36	36	2.48	2.48	248	248	Plus-size 18-inch
235/65R17	35	36	2.41	2.48	241	248	Mid-size SUV
225/60R18	35	35	2.41	2.41	241	241	Highway CUV
255/50R20	37	37	2.55	2.55	255	255	20-inch plus-size

Load notes

Load moves the rear of a SUV / crossover 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

How to set the EX30

Park the Infiniti EX30 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 all-wheel drive EX30 is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this EX30.

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

Infiniti notes

No special Infiniti exception: the EX30 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 Infiniti EX30 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 EX30 than nitrogen upsells.

Questions about this EX30

What tyre pressure should a Infiniti EX30 use?

Catalogue reference is 32-35 psi front and 32-35 psi rear (2.2-2.4 / 2.2-2.4 bar), cold. Confirm on the door-pillar placard.

Front versus rear on the Infiniti EX30?

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.

When does TPMS warn on a Infiniti EX30?

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 EX30?

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

What PSI if I plus-size toward 225/65R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/70R16, 245/60R18 and 225/65R17 as a planning band.
