UK winter mornings will show a lower gauge on this BX5 without a puncture. Set 34/34 psi at ~20 °C equivalent, not after a motorway blast. Under-inflation cooks the shoulders of a BX5; over-inflation wears the centre rib and bangs every cat’s eye.

Temperature and a cold gauge

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this BX5.

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

How to set the BX5

Park the Borgward BX5 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 BX5 is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Borgward BX5 placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this BX5 is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (245/60R18 and others)

Planning cold pressures for sizes often seen on a SUV / crossover. This BX5 sample opens with 245/60R18, then 225/65R17 and 235/60R18.

225/65R17	35	35	2.41	2.41	241	241	Very common 17-inch

Load notes

Load moves the rear of a SUV / crossover 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	36 psi / 2.48 bar

Borgward notes

No special Borgward exception: the BX5 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 BX5 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 BX5

Front versus rear on the Borgward BX5?

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 Borgward BX5 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 BX5?

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

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 235/60R18?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/60R18, 225/65R17 and 235/60R18 as a planning band.
