On a Caravans-Wohnm McLouis the useful pair is 55 psi (3.79 bar) up front and 55 psi (3.79 bar) at the back, mid-range. TPMS typically warns near 41 psi (about 25% below target). That is already a soft tyre, not a fill target.
Caravans-Wohnm notes
No special Caravans-Wohnm exception: the McLouis uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.
Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 55 psi as a 20 °C baseline for this McLouis.
| 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 |
How to set the McLouis
- Park the Caravans-Wohnm McLouis 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 McLouis is enough to feel a pull.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.
Spare and inflator kit
A matching full-size spare on the Caravans-Wohnm McLouis 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.
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 | 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 |

PSI, bar and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the McLouis: 55 psi = 3.79 bar = 379 kPa.
| PSI | Bar | kPa |
|---|---|---|
| 50 | 3.45 | 345 |
| 55 | 3.79 | 379 |
| 60 | 4.14 | 414 |
| 65 | 4.48 | 448 |
Estimated pressure by tyre size (245/40R18 and others)
245/40R18 is the first planning size here. 225/45R17 is usually the plus-size or LT step. Keep load index at or above original equipment.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 245/40R18 | 50 | 50 | 3.45 | 3.45 | 345 | 345 | Wide touring 18-inch |
| 225/40R18 | 50 | 50 | 3.45 | 3.45 | 345 | 345 | Low-profile 18-inch |
| 225/45R17 | 50 | 50 | 3.45 | 3.45 | 345 | 345 | Sport 17-inch |
| 205/55R16 | 50 | 50 | 3.45 | 3.45 | 345 | 345 | Typical mid-compact OEM |
| 215/55R16 | 50 | 50 | 3.45 | 3.45 | 345 | 345 | Slightly wider 16-inch |
| 195/65R15 | 50 | 50 | 3.45 | 3.45 | 345 | 345 | Very common compact |
| 185/65R15 | 50 | 50 | 3.45 | 3.45 | 345 | 345 | Small / older car |
| 205/60R16 | 50 | 50 | 3.45 | 3.45 | 345 | 345 | Taller 16-inch |
Keep the Caravans-Wohnm McLouis on the printed band; use 245/40R18 and 225/45R17 only as a map for non-OEM wheels.

Questions about this McLouis
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 Caravans-Wohnm McLouis?
No. Sidewall PSI is a maximum. The McLouis placard is the operating target, near 45-65/45-65 psi.
How often should I check a McLouis?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
When does TPMS warn on a Caravans-Wohnm McLouis?
Direct TPMS typically flags about 25% below placard — near 41 psi on this row. Fill to the sticker, not to the lamp.
What tyre pressure should a Caravans-Wohnm McLouis use?
Catalogue reference is 45-65 psi front and 45-65 psi rear (3.1-4.5 / 3.1-4.5 bar), cold. Confirm on the door-pillar placard.
