Recommended bar for a Borgward Hansa 1800

Drivetrain: front-wheel drive
Body: passenger car

Bar F / R: 2.2-2.4 / 2.2-2.4

2.3 bar is not 23 psi. On this Hansa 1800 2.2-2.4 bar converts to about 32-35 psi. Use the table, not a guess. Size estimates on this page include 225/45R17, 205/60R16 and 215/55R16 — interpolated from the catalogue midpoint, not a second factory sticker.

Estimated pressure by tyre size (225/45R17 and others)

If your Borgward Hansa 1800 no longer wears the OEM diameter, start at the row nearest 225/45R17 or 205/60R16 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
225/45R17	35	35	2.41	2.41	241	241	Sport 17-inch
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
185/65R15	33	33	2.28	2.28	228	228	Small / older car
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
195/65R15	34	34	2.34	2.34	234	234	Very common compact
225/50R17	35	35	2.41	2.41	241	241	Touring 17-inch

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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	37 psi / 2.55 bar

How to set the Hansa 1800

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Hansa 1800 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.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Hansa 1800.

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

Borgward notes

No special Borgward exception: the Hansa 1800 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 Borgward Hansa 1800 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 Borgward sticker and this page disagree, the sticker wins.

Questions about this Hansa 1800

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.

When does TPMS warn on a Borgward Hansa 1800?

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

What PSI if I plus-size toward 215/55R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/45R17, 205/60R16 and 215/55R16 as a planning band.

What tyre pressure should a Borgward Hansa 1800 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 Hansa 1800?

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