Nissan · 100 NX · Rear

Nissan 100 NX rear tyres: 32-35 psi / 2.2-2.4 bar

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

psi rear

2.31 bar · 231 kPa at the rear axle

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

Loaded 100 NX rears often need the sticker’s second column, not a copy of the front 32-35 psi figure. Under-inflation cooks the shoulders of a 100 NX; over-inflation wears the centre rib and bangs every cat’s eye.

Nissan 100 NX placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this 100 NX is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (225/40R18 and others)

Planning cold pressures for sizes often seen on a passenger car. This 100 NX sample opens with 225/40R18, then 245/40R18 and 205/60R16.

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

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	38 psi / 2.62 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 100 NX.

How to set the 100 NX

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep 100 NX 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 100 NX.

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

Nissan notes

A Qashqai and a Navara do not share a number. Vans and taxis may sit higher than a family hatch.

Spare and inflator kit

A matching full-size spare on the Nissan 100 NX 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 Nissan sticker and this page disagree, the sticker wins.

Questions about this 100 NX

What is that in bar and kPa for the 100 NX?

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

Front versus rear on the Nissan 100 NX?

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 100 NX?

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

When does TPMS warn on a Nissan 100 NX?

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

What tyre pressure should a Nissan 100 NX 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.
