Recommended pressure means the vehicle placard, not the tyre sidewall. For a Ford Ranger Raptor the catalogue proxy is 32-35/32-35 psi (2.2-2.4/2.2-2.4 bar). Size estimates on this page include 275/65R18, LT265/70R17 and 285/70R17 — interpolated from the catalogue midpoint, not a second factory sticker. 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.
How to set the Ranger Raptor
- Park the Ford Ranger Raptor 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 Ranger Raptor is enough to feel a pull.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.
Ford Ranger Raptor placard versus sidewall
The tyre-information placard on a Ford Ranger Raptor 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 (275/65R18 and others)
275/65R18 is the first planning size here. 285/70R17 is usually the plus-size or LT step. Keep load index at or above original equipment.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 275/65R18 | 37 | 40 | 2.55 | 2.76 | 255 | 276 | Plus-size 18-inch |

Pressure against load
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 Ranger Raptor.
| 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 Ranger Raptor 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 Ranger Raptor 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 Ranger Raptor
What is that in bar and kPa for the Ranger Raptor?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
Is the sidewall number correct on a Ford Ranger Raptor?
No. Sidewall PSI is a maximum. The Ranger Raptor placard is the operating target, near 32-35/32-35 psi.
How often should I check a Ranger Raptor?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
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 tyre pressure should a Ford Ranger Raptor 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.
