Treat this page as a map of the BX5 band. The legal setpoint is the printed door-pillar label for your VIN. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Borgward tyre.
How to set the BX5
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep BX5 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.
Borgward BX5 placard versus sidewall
If the Borgward sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.
Estimated pressure by tyre size (225/60R18 and others)
If your Borgward BX5 no longer wears the OEM diameter, start at the row nearest 225/60R18 or 245/55R19 and confirm with the tyre maker’s load table.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 225/60R18 | 35 | 35 | 2.41 | 2.41 | 241 | 241 | Highway CUV |

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 | 37 psi / 2.55 bar |
Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this BX5.
| 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 |
Borgward notes
No special Borgward exception: the BX5 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 Borgward BX5 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.
Keep the Borgward BX5 on the printed band; use 225/60R18 and 235/60R18 only as a map for non-OEM wheels.

Questions about this BX5
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.
Is the sidewall number correct on a Borgward BX5?
No. Sidewall PSI is a maximum. The BX5 placard is the operating target, near 32-35/32-35 psi.
What is that in bar and kPa for the BX5?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
Front versus rear on the Borgward BX5?
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 Borgward BX5 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.
