Treat this page as a map of the Karmann Ghia band. The legal setpoint is the printed door-pillar label for your VIN. Under-inflation cooks the shoulders of a Karmann Ghia; over-inflation wears the centre rib and bangs every cat’s eye.

How to set the Karmann Ghia

Park the Oldtimer Karmann Ghia 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 32-35 psi / 2.2-2.4 bar front and 32-35 psi / 2.2-2.4 bar rear on this catalogue row.
Recheck all four. A 2 psi miss on a front-wheel drive Karmann Ghia is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Oldtimer Karmann Ghia placard versus sidewall

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

Estimated pressure by tyre size (225/50R17 and others)

Planning cold pressures for sizes often seen on a passenger car. This Karmann Ghia sample opens with 225/50R17, then 205/60R16 and 225/40R18.

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	34 psi / 2.34 bar	34 psi / 2.34 bar
Full occupancy	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	38 psi / 2.62 bar

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Karmann Ghia.

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

Oldtimer notes

No special Oldtimer exception: the Karmann Ghia 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 Karmann Ghia 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 Karmann Ghia

Front versus rear on the Oldtimer Karmann Ghia?

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.

When does TPMS warn on a Oldtimer Karmann Ghia?

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

What tyre pressure should a Oldtimer Karmann Ghia 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 PSI if I plus-size toward 225/40R18?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/50R17, 205/60R16 and 225/40R18 as a planning band.

Is the sidewall number correct on a Oldtimer Karmann Ghia?

No. Sidewall PSI is a maximum. The Karmann Ghia placard is the operating target, near 32-35/32-35 psi.
