Cold means the Lexus LX 700h 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 245/60R18, 245/55R19 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.
Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this LX 700h.
| 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 LX 700h
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep LX 700h 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.
Lexus LX 700h placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this LX 700h is the pillar sticker, near 34/34 psi.
Estimated pressure by tyre size (245/60R18 and others)
245/60R18 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 |
|---|---|---|---|---|---|---|---|
| 245/60R18 | 36 | 37 | 2.48 | 2.55 | 248 | 255 | Heavier CUV |
| 245/55R19 | 36 | 36 | 2.48 | 2.48 | 248 | 248 | Low-profile 19-inch |
| 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 | 34 psi / 2.34 bar | 35 psi / 2.41 bar |
| Motorway + luggage | 35 psi / 2.41 bar | 37 psi / 2.55 bar |
Lexus notes
No special Lexus exception: the LX 700h 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 LX 700h 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 LX 700h than nitrogen upsells.

Questions about this LX 700h
What is that in bar and kPa for the LX 700h?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
What PSI if I plus-size toward 215/70R16?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/60R18, 245/55R19 and 215/70R16 as a planning band.
Is the sidewall number correct on a Lexus LX 700h?
No. Sidewall PSI is a maximum. The LX 700h placard is the operating target, near 32-35/32-35 psi.
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 tyre pressure should a Lexus LX 700h 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.
