Treat this page as a map of the XT6 band. The legal setpoint is the printed door-pillar label for your VIN. Under-inflation cooks the shoulders of a XT6; over-inflation wears the centre rib and bangs every cat’s eye. Keep side-to-side spread inside about 2 psi so the all-wheel drive hardware is not working on a radius mismatch.

How to set the XT6

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep XT6 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.

Cadillac XT6 placard versus sidewall

The tyre-information placard on a Cadillac XT6 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 (245/55R19 and others)

Planning cold pressures for sizes often seen on a SUV / crossover. This XT6 sample opens with 245/55R19, then 235/60R18 and 245/60R18.

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
245/60R18	36	37	2.48	2.55	248	255	Heavier CUV
225/60R18	35	35	2.41	2.41	241	241	Highway CUV

225/65R17	35	35	2.41	2.41	241	241	Very common 17-inch

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	37 psi / 2.55 bar

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this XT6.

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

Cadillac notes

No special Cadillac exception: the XT6 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 Cadillac XT6 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 Cadillac sticker and this page disagree, the sticker wins.

Questions about this XT6

Front versus rear on the Cadillac XT6?

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 tyre pressure should a Cadillac XT6 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.

When does TPMS warn on a Cadillac XT6?

Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.

What PSI if I plus-size toward 245/60R18?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/55R19, 235/60R18 and 245/60R18 as a planning band.

Is the sidewall number correct on a Cadillac XT6?

No. Sidewall PSI is a maximum. The XT6 placard is the operating target, near 32-35/32-35 psi.
