Cold means the Lexus RX 200t has stood at least three hours, or covered less than about a mile. Heat from a dual carriageway run is not the number you set. Size estimates on this page include 225/60R18, 225/65R17 and 255/50R20 — interpolated from the catalogue midpoint, not a second factory sticker. Keep side-to-side spread inside about 2 psi so the all-wheel drive hardware is not working on a radius mismatch.

Temperature and a cold gauge

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

How to set the RX 200t

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

Lexus RX 200t placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this RX 200t is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (225/60R18 and others)

225/60R18 is the first planning size here. 255/50R20 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
225/60R18	35	35	2.41	2.41	241	241	Highway CUV
225/65R17	35	35	2.41	2.41	241	241	Very common 17-inch
255/50R20	37	37	2.55	2.55	255	255	20-inch plus-size
235/60R18	36	36	2.48	2.48	248	248	Plus-size 18-inch
245/60R18	36	37	2.48	2.55	248	255	Heavier CUV
235/65R17	35	36	2.41	2.48	241	248	Mid-size SUV
215/70R16	34	34	2.34	2.34	234	234	Compact crossover

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

Lexus notes

No special Lexus exception: the RX 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 RX 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.

A cheap gauge and a monthly habit will do more for this RX 200t than nitrogen upsells.

Questions about this RX 200t

Front versus rear on the Lexus RX 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.

Is the sidewall number correct on a Lexus RX 200t?

No. Sidewall PSI is a maximum. The RX 200t placard is the operating target, near 32-35/32-35 psi.

What tyre pressure should a Lexus RX 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.

When does TPMS warn on a Lexus RX 200t?

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

What PSI if I plus-size toward 255/50R20?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/60R18, 225/65R17 and 255/50R20 as a planning band.
