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 F 100, then fine-tune to the placard. Under-inflation cooks the shoulders of a F 100; 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 245/70R16 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 F 100 sticker uses SI units.

Estimated pressure by tyre size (275/65R18 and others)
Planning cold pressures for sizes often seen on a pickup / double-cab. This F 100 sample opens with 275/65R18, then 285/70R17 and 245/70R16.

Ford F 100 placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this F 100 is the pillar sticker, near 34/34 psi.
Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this F 100.
| 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 F 100
- Park the Ford F 100 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 rear-wheel drive F 100 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 |
Ford notes
Ford UK placards on the F 100 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 100 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 Ford sticker and this page disagree, the sticker wins.

Questions about this F 100
What tyre pressure should a Ford F 100 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.
What PSI if I plus-size toward 245/70R16?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 275/65R18, 285/70R17 and 245/70R16 as a planning band.
What is that in bar and kPa for the F 100?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
Front versus rear on the Ford F 100?
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.
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.
