Jeep Gladiator tyre pressure in kPa

Drivetrain: four-wheel drive
Body: pickup / double-cab
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

kPa

231 / 231

2.31 / 2.31 bar · 32-35 / 32-35 psi

32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa

If your gauge only speaks kPa, aim near 231 / 231 for this Gladiator, then fine-tune to the placard. Under-inflation cooks the shoulders of a Gladiator; over-inflation wears the centre rib and bangs every cat’s eye. Commercial and load-biased bodies like this pickup / double-cab often need a higher rear; LT or C-type sizes such as 285/70R17 are not filled like a Fiesta.

kPa, bar and PSI

kPa-led conversions. 220 kPa is 2.2 bar and about 32 psi — handy if this Gladiator sticker uses SI units.

kPa	Bar	PSI

228	2.28	33

Estimated pressure by tyre size (255/65R17 and others)

255/65R17 is the first planning size here. 285/70R17 is usually the plus-size or LT step. Keep load index at or above original equipment.

Jeep Gladiator placard versus sidewall

If the Jeep sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

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

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.

Load notes

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	37 psi / 2.55 bar

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.

If the Jeep sticker and this page disagree, the sticker wins.

Questions about this Gladiator

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 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.

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.

How often should I check a Gladiator?

Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.

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.
