A 3 psi miss on one front corner of this RX 200t shows up as a wander before the TPMS lamp bothers you. Target 34 psi (2.31 bar) cold. Under-inflation cooks the shoulders of a RX 200t; over-inflation wears the centre rib and bangs every cat’s eye. Keep side-to-side spread inside about 2 psi so the all-wheel drive hardware is not working on a radius mismatch.
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 (235/60R18 and others)
235/60R18 is the first planning size here. 225/60R18 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 |
|---|---|---|---|---|---|---|---|
| 235/60R18 | 36 | — | 2.48 | — | 248 | — | Plus-size 18-inch |
| 225/65R17 | 35 | — | 2.41 | — | 241 | — | Very common 17-inch |
| 225/60R18 | 35 | — | 2.41 | — | 241 | — | Highway CUV |
| 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 |
| 215/70R16 | 34 | — | 2.34 | — | 234 | — | Compact crossover |
| 255/50R20 | 37 | — | 2.55 | — | 255 | — | 20-inch plus-size |
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 | 35 psi / 2.41 bar | 36 psi / 2.48 bar |
| Motorway + luggage | 36 psi / 2.48 bar | 38 psi / 2.62 bar |
Steering feel on the RX 200t lives on this axle. Do not drop front pressure to “soften” a plus-size 225/60R18; you will roll the sidewall in a roundabout.
How to set the RX 200t
- Park the Lexus RX 200t 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 all-wheel drive RX 200t is enough to feel a pull.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.

Temperature drift
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 |
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
What is that in bar and kPa for the RX 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.
How often should I check a RX 200t?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
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.
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.
