35-45 psi F · 45-65 psi R · 2.4-3.1 / 3.1-4.5 bar · 276/379 kPa
The Nissan Expert catalogue band is 35-45 psi front and 45-65 psi rear — 2.4-3.1 / 3.1-4.5 bar, or about 276 / 379 kPa — measured cold. Size estimates on this page include 275/65R18, 235/75R15 and 245/70R16 — interpolated from the catalogue midpoint, not a second factory sticker.
Spare and inflator kit
A matching full-size spare on the Nissan Expert usually follows the higher axle (often the rear, near 45-65 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.
PSI, bar and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the Expert: 40 psi = 2.76 bar = 276 kPa.
| PSI | Bar | kPa |
|---|---|---|
| 35 | 2.41 | 241 |
| 36 | 2.48 | 248 |
| 38 | 2.62 | 262 |
| 40 | 2.76 | 276 |

| 60 | 4.14 | 414 |

Nissan notes
A Qashqai and a Navara do not share a number. Vans and taxis may sit higher than a family hatch.
Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 40 psi as a 20 °C baseline for this Expert.
| Ambient | Gauge (front mid) | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 37 psi | 2.55 bar | 255 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 38 psi | 2.62 bar | 262 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 39 psi | 2.69 bar | 269 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 40 psi | 2.76 bar | 276 kPa | Baseline |
| 30 °C | 42 psi | 2.9 bar | 290 kPa | Do not bleed a hot tyre |
| 38 °C (heatwave tarmac) | 43 psi | 2.96 bar | 296 kPa | Do not bleed a hot tyre |
Pressure against load
Load moves the rear of a light commercial first. If the factory placard already has a “laden” column, use that instead of these sketches.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only | 40 psi / 2.76 bar | 55 psi / 3.79 bar |
| Full occupancy | 40 psi / 2.76 bar | 56 psi / 3.86 bar |
| Motorway + luggage | 41 psi / 2.83 bar | 59 psi / 4.07 bar |
Nissan Expert placard versus sidewall
The tyre-information placard on a Nissan Expert sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 35-45 / 45-65 psi.
Estimated pressure by tyre size (275/65R18 and others)
275/65R18 is the first planning size here. 245/70R16 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 |
|---|---|---|---|---|---|---|---|
| 275/65R18 | 43 | 61 | 2.96 | 4.21 | 296 | 421 | Plus-size 18-inch |
| 235/75R15 | 41 | 58 | 2.83 | 4 | 283 | 400 | Older compact truck |
| 245/70R16 | 42 | 59 | 2.9 | 4.07 | 290 | 407 | Common 16-inch all-terrain |
| LT245/75R16 | 48 | 67 | 3.31 | 4.62 | 331 | 462 | LT-metric, higher load |
| 285/70R17 | 44 | 62 | 3.03 | 4.27 | 303 | 427 | Wide all-terrain |
| LT265/70R17 | 48 | 69 | 3.31 | 4.76 | 331 | 476 | LT 17-inch |
| 255/65R17 | 43 | 60 | 2.96 | 4.14 | 296 | 414 | Highway 17-inch |
| 265/70R17 | 43 | 60 | 2.96 | 4.14 | 296 | 414 | Typical 17-inch load tyre |
How to set the Expert
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Expert numbers in your head.
- Add air in short bursts toward 40 psi (2.76 bar) front and 55 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.
If the Nissan sticker and this page disagree, the sticker wins.

Questions about this Expert
Front versus rear on the Nissan Expert?
This row is 35-45 F / 45-65 R. Even when they match, a laden rear can justify a higher number if the sticker prints one.
What PSI if I plus-size toward 245/70R16?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 275/65R18, 235/75R15 and 245/70R16 as a planning band.
What tyre pressure should a Nissan Expert use?
Catalogue reference is 35-45 psi front and 45-65 psi rear (2.4-3.1 / 3.1-4.5 bar), cold. Confirm on the door-pillar placard.
Is the sidewall number correct on a Nissan Expert?
No. Sidewall PSI is a maximum. The Expert placard is the operating target, near 35-45/45-65 psi.
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.
