European and UK handbooks usually quote bar. The Caravans-Wohnm Niesmann+Bischoff catalogue is 3.1-4.5 bar front and 3.1-4.5 bar rear (midpoint 3.79 / 3.79). A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Caravans-Wohnm tyre.

Caravans-Wohnm Niesmann+Bischoff placard versus sidewall
The tyre-information placard on a Caravans-Wohnm Niesmann+Bischoff sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 45-65 / 45-65 psi.
Estimated pressure by tyre size (195/65R15 and others)
Planning cold pressures for sizes often seen on a passenger car. This Niesmann+Bischoff sample opens with 195/65R15, then 185/65R15 and 215/55R16.

Load notes
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 | 50 psi / 3.45 bar | 50 psi / 3.45 bar |
| Full occupancy | 50 psi / 3.45 bar | 50 psi / 3.45 bar |
| Motorway + luggage | 50 psi / 3.45 bar | 50 psi / 3.45 bar |
How to set the Niesmann+Bischoff
- Park the Caravans-Wohnm Niesmann+Bischoff 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 45-65 psi / 3.1-4.5 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 Niesmann+Bischoff 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 55 psi as a 20 °C baseline for this Niesmann+Bischoff.
| Ambient | Gauge (front mid) | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 52 psi | 3.59 bar | 359 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 53 psi | 3.65 bar | 365 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 54 psi | 3.72 bar | 372 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 55 psi | 3.79 bar | 379 kPa | Baseline |
| 30 °C | 57 psi | 3.93 bar | 393 kPa | Do not bleed a hot tyre |
| 38 °C (heatwave tarmac) | 58 psi | 4 bar | 400 kPa | Do not bleed a hot tyre |
Caravans-Wohnm notes
No special Caravans-Wohnm exception: the Niesmann+Bischoff 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 Caravans-Wohnm Niesmann+Bischoff 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.
If the Caravans-Wohnm sticker and this page disagree, the sticker wins.

Questions about this Niesmann+Bischoff
What PSI if I plus-size toward 215/55R16?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 195/65R15, 185/65R15 and 215/55R16 as a planning band.
When does TPMS warn on a Caravans-Wohnm Niesmann+Bischoff?
Direct TPMS typically flags about 25% below placard — near 41 psi on this row. Fill to the sticker, not to the lamp.
How often should I check a Niesmann+Bischoff?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
Is the sidewall number correct on a Caravans-Wohnm Niesmann+Bischoff?
No. Sidewall PSI is a maximum. The Niesmann+Bischoff placard is the operating target, near 45-65/45-65 psi.
Front versus rear on the Caravans-Wohnm Niesmann+Bischoff?
This row is 45-65 F / 45-65 R. Even when they match, a laden rear can justify a higher number if the sticker prints one.
