European and UK handbooks usually quote bar. The Oldtimer Minerva 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 Minerva 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 (215/50R17 and others)

215/50R17 is the first planning size here. 185/65R15 is usually the plus-size or LT step. Keep load index at or above original equipment.

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 Minerva

  1. Park the Oldtimer Minerva 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 Minerva 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 Minerva.

Oldtimer notes

No special Oldtimer exception: the Minerva 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 Minerva 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 Oldtimer sticker and this page disagree, the sticker wins.

Questions about this Minerva

When does TPMS warn on a Oldtimer Minerva?

Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.

Front versus rear on the Oldtimer Minerva?

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 Minerva 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 Minerva?

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

How often should I check a Minerva?

Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
