The rear of a pickup / double-cab takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the Jeep Gladiator is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include LT245/75R16, LT265/70R17 and 265/70R17 — interpolated from the catalogue midpoint, not a second factory sticker. Commercial and load-biased bodies like this pickup / double-cab often need a higher rear; LT or C-type sizes such as 265/70R17 are not filled like a Fiesta.
Jeep Gladiator placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this Gladiator is the pillar sticker, near 34/34 psi.
Estimated pressure by tyre size (LT245/75R16 and others)
LT245/75R16 is the first planning size here. 265/70R17 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 |
|---|---|---|---|---|---|---|---|
| LT245/75R16 | — | 46 | — | 3.17 | — | 317 | LT-metric, higher load |
| LT265/70R17 | — | 48 | — | 3.31 | — | 331 | LT 17-inch |
| 265/70R17 | — | 39 | — | 2.69 | — | 269 | Typical 17-inch load tyre |
| 255/65R17 | — | 39 | — | 2.69 | — | 269 | Highway 17-inch |
| 285/70R17 | — | 41 | — | 2.83 | — | 283 | Wide all-terrain |
| 275/65R18 | — | 40 | — | 2.76 | — | 276 | Plus-size 18-inch |
| 245/70R16 | — | 38 | — | 2.62 | — | 262 | Common 16-inch all-terrain |
| 235/75R15 | — | 37 | — | 2.55 | — | 255 | Older compact truck |
Pressure against load
Load moves the rear of a pickup / double-cab 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 |
| Payload / towing | 36 psi / 2.48 bar | 38 psi / 2.62 bar |
A family pickup / double-cab with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this Gladiator.
How to set the Gladiator
- Park the Jeep Gladiator 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 Gladiator 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 Gladiator.
| 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 notes
No special Jeep exception: the Gladiator 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 Jeep Gladiator 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.
Keep the Jeep Gladiator on the printed band; use LT245/75R16 and 265/70R17 only as a map for non-OEM wheels.

Questions about this Gladiator
Front versus rear on the Jeep Gladiator?
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 is that in bar and kPa for the Gladiator?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
When does TPMS warn on a Jeep Gladiator?
Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.
Is the sidewall number correct on a Jeep Gladiator?
No. Sidewall PSI is a maximum. The Gladiator placard is the operating target, near 32-35/32-35 psi.
What PSI if I plus-size toward 265/70R17?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use LT245/75R16, LT265/70R17 and 265/70R17 as a planning band.
