The rear of a SUV / crossover takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the Changhe X5 is 32-35 psi / 2.2-2.4 bar. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.
Changhe X5 placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this X5 is the pillar sticker, near 34/34 psi.
Estimated pressure by tyre size (245/55R19 and others)
If your Changhe X5 no longer wears the OEM diameter, start at the row nearest 245/55R19 or 215/70R16 and confirm with the tyre maker’s load table.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 245/55R19 | — | 36 | — | 2.48 | — | 248 | Low-profile 19-inch |
| 215/70R16 | — | 34 | — | 2.34 | — | 234 | Compact crossover |
| 235/65R17 | — | 36 | — | 2.48 | — | 248 | Mid-size SUV |
| 255/50R20 | — | 37 | — | 2.55 | — | 255 | 20-inch plus-size |

Pressure against load
Load moves the rear of a SUV / crossover 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 | 38 psi / 2.62 bar |
A family SUV / crossover 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 X5.
How to set the X5
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep X5 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 X5.
| 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 |
Changhe notes
No special Changhe exception: the X5 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 Changhe X5 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 Changhe sticker and this page disagree, the sticker wins.

Questions about this X5
Front versus rear on the Changhe X5?
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 PSI if I plus-size toward 235/65R17?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/55R19, 215/70R16 and 235/65R17 as a planning band.
Is the sidewall number correct on a Changhe X5?
No. Sidewall PSI is a maximum. The X5 placard is the operating target, near 32-35/32-35 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.
What is that in bar and kPa for the X5?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
