This four-wheel drive SUV / crossover is filed here with a working range of 32-35/32-35 psi. The pillar sticker on your VIN still overrides the website. Size estimates on this page include 245/55R19, 235/60R18 and 225/65R17 — interpolated from the catalogue midpoint, not a second factory sticker. Keep side-to-side spread inside about 2 psi so the four-wheel drive hardware is not working on a radius mismatch.
PSI, bar and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the Grand Cherokee: 34 psi = 2.31 bar = 231 kPa.

Jeep notes
No special Jeep exception: the Grand Cherokee uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.
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 | 36 psi / 2.48 bar |
How to set the Grand Cherokee
- Park the Jeep Grand Cherokee 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 four-wheel drive Grand Cherokee is enough to feel a pull.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.
Spare and inflator kit
A matching full-size spare on the Jeep Grand Cherokee 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.
Estimated pressure by tyre size (245/55R19 and others)
245/55R19 is the first planning size here. 225/65R17 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 |
|---|---|---|---|---|---|---|---|
| 245/55R19 | 36 | 36 | 2.48 | 2.48 | 248 | 248 | Low-profile 19-inch |
| 235/60R18 | 36 | 36 | 2.48 | 2.48 | 248 | 248 | Plus-size 18-inch |
| 225/65R17 | 35 | 35 | 2.41 | 2.41 | 241 | 241 | Very common 17-inch |
| 235/65R17 | 35 | 36 | 2.41 | 2.48 | 241 | 248 | Mid-size SUV |

| 255/50R20 | 37 | 37 | 2.55 | 2.55 | 255 | 255 | 20-inch plus-size |

Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Grand Cherokee.
| 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 |
Jeep Grand Cherokee placard versus sidewall
If the Jeep sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.
A cheap gauge and a monthly habit will do more for this Grand Cherokee than nitrogen upsells.

Questions about this Grand Cherokee
What is that in bar and kPa for the Grand Cherokee?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
Is the sidewall number correct on a Jeep Grand Cherokee?
No. Sidewall PSI is a maximum. The Grand Cherokee placard is the operating target, near 32-35/32-35 psi.
What PSI if I plus-size toward 225/65R17?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/55R19, 235/60R18 and 225/65R17 as a planning band.
When does TPMS warn on a Jeep Grand Cherokee?
Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.
What tyre pressure should a Jeep Grand Cherokee 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.
