A De la Chapelle Type 55 Tourer run at sidewall-max (often 44–51 psi) is over-inflated for this passenger car. The operating PSI is 32-35/32-35. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed De la Chapelle tyre.

Sidewall PSI is a carcass maximum. Recommended operating pressure for this Type 55 Tourer is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (205/60R16 and others)
Planning cold pressures for sizes often seen on a passenger car. This Type 55 Tourer sample opens with 205/60R16, then 225/45R17 and 195/65R15.

How to set the Type 55 Tourer
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Type 55 Tourer 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.
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 | 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 | 36 psi / 2.48 bar |
Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Type 55 Tourer.
| 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 |
De la Chapelle notes
No special De la Chapelle exception: the Type 55 Tourer 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 De la Chapelle Type 55 Tourer 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 De la Chapelle sticker and this page disagree, the sticker wins.

Questions about this Type 55 Tourer
How often should I check a Type 55 Tourer?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
What is that in bar and kPa for the Type 55 Tourer?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
When does TPMS warn on a De la Chapelle Type 55 Tourer?
Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.
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 PSI if I plus-size toward 195/65R15?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 205/60R16, 225/45R17 and 195/65R15 as a planning band.
