Front axle PSI and bar on the Lexus NX 200t

Drivetrain: all-wheel drive
Body: SUV / crossover
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

psi front

2.31 bar · 231 kPa at the steering axle

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

The front axle of a Lexus NX 200t steers and, on all-wheel drive cars, often pulls as well. Catalogue front pressure is 32-35 psi / 2.2-2.4 bar. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target. Keep side-to-side spread inside about 2 psi so the all-wheel drive hardware is not working on a radius mismatch.

Lexus NX 200t placard versus sidewall

If the Lexus sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

Estimated pressure by tyre size (255/50R20 and others)

If your Lexus NX 200t no longer wears the OEM diameter, start at the row nearest 255/50R20 or 245/55R19 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
255/50R20	37	—	2.55	—	255	—	20-inch plus-size
245/55R19	36	—	2.48	—	248	—	Low-profile 19-inch
245/60R18	36	—	2.48	—	248	—	Heavier CUV
235/65R17	35	—	2.41	—	241	—	Mid-size SUV
225/60R18	35	—	2.41	—	241	—	Highway CUV
235/60R18	36	—	2.48	—	248	—	Plus-size 18-inch
225/65R17	35	—	2.41	—	241	—	Very common 17-inch
215/70R16	34	—	2.34	—	234	—	Compact crossover

Pressure against load

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

Steering feel on the NX 200t lives on this axle. Do not drop front pressure to “soften” a plus-size 245/60R18; you will roll the sidewall in a roundabout.

How to set the NX 200t

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep NX 200t 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.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this NX 200t.

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 NX 200t 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 NX 200t 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.

Keep the Lexus NX 200t on the printed band; use 255/50R20 and 245/60R18 only as a map for non-OEM wheels.

Questions about this NX 200t

Front versus rear on the Lexus NX 200t?

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 PSI if I plus-size toward 245/60R18?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 255/50R20, 245/55R19 and 245/60R18 as a planning band.

What tyre pressure should a Lexus NX 200t 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 NX 200t?

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.
