European and UK handbooks usually quote bar. The Oldtimer Morgan Darmont catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

Oldtimer Morgan Darmont placard versus sidewall

If the Oldtimer sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

Estimated pressure by tyre size (225/40R18 and others)

If your Oldtimer Morgan Darmont no longer wears the OEM diameter, start at the row nearest 225/40R18 or 245/40R18 and confirm with the tyre maker’s load table.

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.

How to set the Morgan Darmont

  1. Park the Oldtimer Morgan Darmont for at least three hours (cold tyres).
  2. Use a calibrated gauge, not the only meter on a forecourt hose.
  3. Set the placard for that axle — about 32-35 psi / 2.2-2.4 bar front and 32-35 psi / 2.2-2.4 bar rear on this catalogue row.
  4. Recheck all four. A 2 psi miss on a front-wheel drive Morgan Darmont is enough to feel a pull.
  5. 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 34 psi as a 20 °C baseline for this Morgan Darmont.

Oldtimer notes

No special Oldtimer exception: the Morgan Darmont 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 Oldtimer Morgan Darmont 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.

A cheap gauge and a monthly habit will do more for this Morgan Darmont than nitrogen upsells.

Questions about this Morgan Darmont

Front versus rear on the Oldtimer Morgan Darmont?

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 Oldtimer Morgan Darmont 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.

What is that in bar and kPa for the Morgan Darmont?

Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.

What PSI if I plus-size toward 185/65R15?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/40R18, 245/40R18 and 185/65R15 as a planning band.

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.
