A front-wheel drive Nissan 280 ZX still wants even corners. 2.2-2.4 vs 2.2-2.4 is an axle split, not a left-right split. Size estimates on this page include 215/55R16, 185/65R15 and 245/40R18 — interpolated from the catalogue midpoint, not a second factory sticker.

Nissan 280 ZX placard versus sidewall

If the Nissan sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

Estimated pressure by tyre size (215/55R16 and others)

If your Nissan 280 ZX no longer wears the OEM diameter, start at the row nearest 215/55R16 or 185/65R15 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
185/65R15	33	33	2.28	2.28	228	228	Small / older car
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
195/65R15	34	34	2.34	2.34	234	234	Very common compact
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
225/50R17	35	35	2.41	2.41	241	241	Touring 17-inch

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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	36 psi / 2.48 bar

How to set the 280 ZX

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep 280 ZX 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.
Log date, ambient temperature and the four readings.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this 280 ZX.

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 280 ZX 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.

Keep the Nissan 280 ZX on the printed band; use 215/55R16 and 245/40R18 only as a map for non-OEM wheels.

Questions about this 280 ZX

Is the sidewall number correct on a Nissan 280 ZX?

No. Sidewall PSI is a maximum. The 280 ZX placard is the operating target, near 32-35/32-35 psi.

What tyre pressure should a Nissan 280 ZX 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 Nissan 280 ZX?

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 Nissan 280 ZX?

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

How often should I check a 280 ZX?

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