Ford · F 150 · PSI

Ford F 150 inflation in PSI (32-35 front, 32-35 rear)

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

If a F 150 owner asks “what PSI?”, start at 34 at the steering axle and 34 at the rear, then confirm the placard. Under-inflation cooks the shoulders of a F 150; 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 265/70R17 are not filled like a Fiesta.

Estimated pressure by tyre size (235/75R15 and others)

If your Ford F 150 no longer wears the OEM diameter, start at the row nearest 235/75R15 or LT245/75R16 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
235/75R15	35	37	2.41	2.55	241	255	Older compact truck

How to set the F 150

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep F 150 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.

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	34 psi / 2.34 bar	35 psi / 2.41 bar
Payload / towing	35 psi / 2.41 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 F 150.

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

Ford notes

Ford UK placards on the F 150 are often printed in PSI even when the handbook also shows bar. A Mondeo, Focus or Kuga does not share a Transit number. Loaded vans use the second column.

Spare and inflator kit

A matching full-size spare on the Ford F 150 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 Ford F 150 on the printed band; use 235/75R15 and 265/70R17 only as a map for non-OEM wheels.

Questions about this F 150

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 235/75R15, LT245/75R16 and 265/70R17 as a planning band.

Is the sidewall number correct on a Ford F 150?

No. Sidewall PSI is a maximum. The F 150 placard is the operating target, near 32-35/32-35 psi.

How often should I check a F 150?

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

When does TPMS warn on a Ford F 150?

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

Front versus rear on the Ford F 150?

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.
