Lexus LM rear tyres: 32-35 psi / 2.2-2.4 bar

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

psi rear

2.31 bar · 231 kPa at the rear axle

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

The rear of a passenger car takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the Lexus LM is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include 205/55R16, 245/40R18 and 185/65R15 — interpolated from the catalogue midpoint, not a second factory sticker.

Estimated pressure by tyre size (205/55R16 and others)

205/55R16 is the first planning size here. 185/65R15 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
205/55R16	—	34	—	2.34	—	234	Typical mid-compact OEM
245/40R18	—	36	—	2.48	—	248	Wide touring 18-inch
185/65R15	—	33	—	2.28	—	228	Small / older car
225/45R17	—	35	—	2.41	—	241	Sport 17-inch
225/50R17	—	35	—	2.41	—	241	Touring 17-inch
205/60R16	—	34	—	2.34	—	234	Taller 16-inch
215/55R16	—	35	—	2.41	—	241	Slightly wider 16-inch
195/65R15	—	34	—	2.34	—	234	Very common compact

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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	38 psi / 2.62 bar

A family passenger car with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this LM.

How to set the LM

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

PSI, bar and kPa

PSI-led conversions for the Lexus LM band (32-35 / 32-35).

PSI	Bar	kPa
30	2.07	207
32	2.21	221
33	2.28	228
33.5	2.31	231

Temperature drift

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

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

Lexus notes

No special Lexus exception: the LM 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 Lexus LM 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 Lexus sticker and this page disagree, the sticker wins.

Questions about this LM

What is that in bar and kPa for the LM?

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

When does TPMS warn on a Lexus LM?

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 Lexus LM?

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

What tyre pressure should a Lexus LM 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 185/65R15?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 205/55R16, 245/40R18 and 185/65R15 as a planning band.
