What PSI for a Oldtimer LMX?

Drivetrain: front-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

psi

34 / 34

Catalogue mid-points, front / rear · 2.2-2.4 / 2.2-2.4 bar

32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa

If a LMX owner asks “what PSI?”, start at 34 at the steering axle and 34 at the rear, then confirm the placard. Size estimates on this page include 195/65R15, 205/55R16 and 205/60R16 — interpolated from the catalogue midpoint, not a second factory sticker.

Oldtimer LMX placard versus sidewall

The tyre-information placard on a Oldtimer LMX sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

Estimated pressure by tyre size (195/65R15 and others)

195/65R15 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
195/65R15	34	34	2.34	2.34	234	234	Very common compact
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
185/65R15	33	33	2.28	2.28	228	228	Small / older car
225/45R17	35	35	2.41	2.41	241	241	Sport 17-inch
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch

How to set the LMX

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

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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	37 psi / 2.55 bar

Temperature drift

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

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 LMX 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 LMX 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 LMX

Front versus rear on the Oldtimer LMX?

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 is that in bar and kPa for the LMX?

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

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 195/65R15, 205/55R16 and 205/60R16 as a planning band.

How often should I check a LMX?

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

Is the sidewall number correct on a Oldtimer LMX?

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