Cold tyre pressure for a Oldtimer De Lorean

Body: passenger car

UK winter mornings will show a lower gauge on this De Lorean without a puncture. Set 34/34 psi at ~20 °C equivalent, not after a motorway blast. Under-inflation cooks the shoulders of a De Lorean; 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 De Lorean.

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 De Lorean

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

Oldtimer De Lorean placard versus sidewall

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

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

225/45R17 is the first planning size here. 205/60R16 is usually the plus-size or LT step. Keep load index at or above original equipment.

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
195/65R15	34	34	2.34	2.34	234	234	Very common compact
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
185/65R15	33	33	2.28	2.28	228	228	Small / older car

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

Oldtimer notes

No special Oldtimer exception: the De Lorean 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 De Lorean 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 De Lorean

Front versus rear on the Oldtimer De Lorean?

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 De Lorean?

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

Is the sidewall number correct on a Oldtimer De Lorean?

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

What PSI if I plus-size toward 205/60R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/45R17, 195/65R15 and 205/60R16 as a planning band.

What is that in bar and kPa for the De Lorean?

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