Jeep Gladiator tyre pressure in bar

32-35 / 32-35 psi · 231 / 231 kPa

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

A four-wheel drive Jeep Gladiator still wants even corners. 2.2-2.4 vs 2.2-2.4 is an axle split, not a left-right split. 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 235/75R15 are not filled like a Fiesta.

Jeep Gladiator placard versus sidewall

The tyre-information placard on a Jeep Gladiator sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

Estimated pressure by tyre size (265/70R17 and others)

Planning cold pressures for sizes often seen on a pickup / double-cab. This Gladiator sample opens with 265/70R17, then LT265/70R17 and 235/75R15.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
265/70R17	37	39	2.55	2.69	255	269	Typical 17-inch load tyre
LT265/70R17	42	48	2.9	3.31	290	331	LT 17-inch
235/75R15	35	37	2.41	2.55	241	255	Older compact truck
255/65R17	37	39	2.55	2.69	255	269	Highway 17-inch
245/70R16	36	38	2.48	2.62	248	262	Common 16-inch all-terrain
285/70R17	38	41	2.62	2.83	262	283	Wide all-terrain
275/65R18	37	40	2.55	2.76	255	276	Plus-size 18-inch
LT245/75R16	42	46	2.9	3.17	290	317	LT-metric, higher load

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	36 psi / 2.48 bar

How to set the Gladiator

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Gladiator 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.

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.

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.

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 PSI if I plus-size toward 235/75R15?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 265/70R17, LT265/70R17 and 235/75R15 as a planning band.

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.

How often should I check a Gladiator?

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