Kilopascals show up on some Asian stickers and ISO sheets. 231 kPa front and 231 kPa rear is the Lexus RX 200t midpoint (100 kPa = 1 bar). Size estimates on this page include 255/50R20, 225/65R17 and 215/70R16 — 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.
kPa, bar and PSI
kPa-led conversions. 220 kPa is 2.2 bar and about 32 psi — handy if this RX 200t sticker uses SI units.
| kPa | Bar | PSI |
|---|---|---|
| 207 | 2.07 | 30 |
| 221 | 2.21 | 32 |
| 228 | 2.28 | 33 |
| 231 | 2.31 | 33.5 |
| 241 | 2.41 | 35 |
| 248 | 2.48 | 36 |
| 262 | 2.62 | 38 |
| 276 | 2.76 | 40 |
| 303 | 3.03 | 44 |

Estimated pressure by tyre size (255/50R20 and others)
255/50R20 is the first planning size here. 215/70R16 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 |
|---|---|---|---|---|---|---|---|
| 255/50R20 | 37 | 37 | 2.55 | 2.55 | 255 | 255 | 20-inch plus-size |
| 225/65R17 | 35 | 35 | 2.41 | 2.41 | 241 | 241 | Very common 17-inch |
| 215/70R16 | 34 | 34 | 2.34 | 2.34 | 234 | 234 | Compact crossover |
| 235/65R17 | 35 | 36 | 2.41 | 2.48 | 241 | 248 | Mid-size SUV |
| 225/60R18 | 35 | 35 | 2.41 | 2.41 | 241 | 241 | Highway CUV |
| 235/60R18 | 36 | 36 | 2.48 | 2.48 | 248 | 248 | Plus-size 18-inch |
| 245/55R19 | 36 | 36 | 2.48 | 2.48 | 248 | 248 | Low-profile 19-inch |
| 245/60R18 | 36 | 37 | 2.48 | 2.55 | 248 | 255 | Heavier CUV |
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.
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 |
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.
- Log date, ambient temperature and the four readings.
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 | 34 psi / 2.34 bar | 35 psi / 2.41 bar |
| Motorway + luggage | 35 psi / 2.41 bar | 38 psi / 2.62 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.
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.
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.
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.
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.
