The rear of a light commercial takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the Fiat Scudo is 45-65 psi / 3.1-4.5 bar. Size estimates on this page include 265/70R17, 235/75R15 and 285/70R17 — interpolated from the catalogue midpoint, not a second factory sticker.
Fiat Scudo placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this Scudo is the pillar sticker, near 40/55 psi.
Estimated pressure by tyre size (265/70R17 and others)
Planning cold pressures for sizes often seen on a light commercial. This Scudo sample opens with 265/70R17, then 235/75R15 and 285/70R17.

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 |
A family light commercial 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 Scudo.
How to set the Scudo
- Park the Fiat Scudo 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 35-45 psi / 2.4-3.1 bar front and 45-65 psi / 3.1-4.5 bar rear on this catalogue row.
- Recheck all four. A 2 psi miss on a front-wheel drive Scudo 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 40 psi as a 20 °C baseline for this Scudo.
| 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 |
Fiat notes
No special Fiat exception: the Scudo 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 Fiat Scudo 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.
A cheap gauge and a monthly habit will do more for this Scudo than nitrogen upsells.

Questions about this Scudo
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.
What tyre pressure should a Fiat Scudo 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 Fiat Scudo?
No. Sidewall PSI is a maximum. The Scudo placard is the operating target, near 35-45/45-65 psi.
When does TPMS warn on a Fiat Scudo?
Direct TPMS typically flags about 25% below placard — near 30 psi on this row. Fill to the sticker, not to the lamp.
What is that in bar and kPa for the Scudo?
Mid-points are about 2.76 bar (276 kPa) front and 3.79 bar (379 kPa) rear.
