32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa
The rear of a passenger car takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the Mitsubishi Santamo is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include 245/40R18, 225/50R17 and 225/45R17 — interpolated from the catalogue midpoint, not a second factory sticker.
Mitsubishi Santamo placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this Santamo is the pillar sticker, near 34/34 psi.
Estimated pressure by tyre size (245/40R18 and others)
If your Mitsubishi Santamo no longer wears the OEM diameter, start at the row nearest 245/40R18 or 225/50R17 and confirm with the tyre maker’s load table.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 245/40R18 | — | 36 | — | 2.48 | — | 248 | Wide touring 18-inch |
| 225/50R17 | — | 35 | — | 2.41 | — | 241 | Touring 17-inch |
| 225/45R17 | — | 35 | — | 2.41 | — | 241 | Sport 17-inch |
| 215/55R16 | — | 35 | — | 2.41 | — | 241 | Slightly wider 16-inch |
| 185/65R15 | — | 33 | — | 2.28 | — | 228 | Small / older car |
| 215/50R17 | — | 35 | — | 2.41 | — | 241 | Plus-size 17-inch |

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 | 35 psi / 2.41 bar | 36 psi / 2.48 bar |
| Motorway + luggage | 36 psi / 2.48 bar | 37 psi / 2.55 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 Santamo.
How to set the Santamo
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Santamo 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 Santamo.
| 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 |
Mitsubishi notes
No special Mitsubishi exception: the Santamo 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 Mitsubishi Santamo 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 Mitsubishi sticker and this page disagree, the sticker wins.

Questions about this Santamo
What is that in bar and kPa for the Santamo?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
How often should I check a Santamo?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
When does TPMS warn on a Mitsubishi Santamo?
Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.
Front versus rear on the Mitsubishi Santamo?
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.
What tyre pressure should a Mitsubishi Santamo 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.
