The Fiat Ducato 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 215/65R16, 225/75R16 and 195/75R16C — interpolated from the catalogue midpoint, not a second factory sticker. Commercial and load-biased bodies like this van often need a higher rear; LT or C-type sizes such as 195/75R16C are not filled like a Fiesta.
Fiat Ducato placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this Ducato is the pillar sticker, near 40/55 psi.
Pressure against load
Load moves the rear of a van 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 |
| Payload / towing | 41 psi / 2.83 bar | 59 psi / 4.07 bar |
Estimated pressure by tyre size (215/65R16 and others)
If your Fiat Ducato no longer wears the OEM diameter, start at the row nearest 215/65R16 or 225/75R16 and confirm with the tyre maker’s load table.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 215/65R16 | 40 | 57 | 2.76 | 3.93 | 276 | 393 | Compact van |

How to set the Ducato
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Ducato 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.
Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 40 psi as a 20 °C baseline for this Ducato.
| 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 |
PSI, bar and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the Ducato: 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 |
| 44 | 3.03 | 303 |
| 45 | 3.10 | 310 |
| 50 | 3.45 | 345 |
| 55 | 3.79 | 379 |
| 60 | 4.14 | 414 |
| 65 | 4.48 | 448 |
Spare and inflator kit
A matching full-size spare on the Fiat Ducato 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.
Fiat notes
No special Fiat exception: the Ducato uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.
Keep the Fiat Ducato on the printed band; use 215/65R16 and 195/75R16C only as a map for non-OEM wheels.

Questions about this Ducato
What PSI if I plus-size toward 195/75R16C?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/65R16, 225/75R16 and 195/75R16C as a planning band.
Front versus rear on the Fiat Ducato?
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.
How often should I check a Ducato?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
Is the sidewall number correct on a Fiat Ducato?
No. Sidewall PSI is a maximum. The Ducato 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.
