Loaded Transit Custom rears often need the sticker’s second column, not a copy of the front 35-45 psi figure. Under-inflation cooks the shoulders of a Transit Custom; over-inflation wears the centre rib and bangs every cat’s eye. Commercial and load-biased bodies like this van often need a higher rear; LT or C-type sizes such as 235/60R17 are not filled like a Fiesta.
Ford Transit Custom placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this Transit Custom is the pillar sticker, near 40/55 psi.
Estimated pressure by tyre size (195/75R16C and others)
195/75R16C is the first planning size here. 235/60R17 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 |

Pressure against load
Load moves the rear of a van first. If the factory placard already has a “laden” column, use that instead of these sketches.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only | 40 psi / 2.76 bar | 55 psi / 3.79 bar |
| Full occupancy | 41 psi / 2.83 bar | 57 psi / 3.93 bar |
| Payload / towing | 42 psi / 2.9 bar | 58 psi / 4 bar |
A family van with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this Transit Custom.
How to set the Transit Custom
- Park the Ford Transit Custom 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 35-45 psi / 2.4-3.1 bar front and 45-65 psi / 3.1-4.5 bar rear on this catalogue row.
- Recheck all four. A 2 psi miss on a front-wheel drive Transit Custom is enough to feel a pull.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.

Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 40 psi as a 20 °C baseline for this Transit Custom.
| Ambient | Gauge (front mid) | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 37 psi | 2.55 bar | 255 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 38 psi | 2.62 bar | 262 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 39 psi | 2.69 bar | 269 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 40 psi | 2.76 bar | 276 kPa | Baseline |
| 30 °C | 42 psi | 2.9 bar | 290 kPa | Do not bleed a hot tyre |
| 38 °C (heatwave tarmac) | 43 psi | 2.96 bar | 296 kPa | Do not bleed a hot tyre |
Ford notes
Ford UK placards on the Transit Custom 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 Transit Custom usually follows the higher axle (often the rear, near 45-65 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 Transit Custom on the printed band; use 195/75R16C and 235/60R17 only as a map for non-OEM wheels.

Questions about this Transit Custom
What tyre pressure should a Ford Transit Custom use?
Catalogue reference is 35-45 psi front and 45-65 psi rear (2.4-3.1 / 3.1-4.5 bar), cold. Confirm on the door-pillar placard.
How often should I check a Transit Custom?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
What PSI if I plus-size toward 235/60R17?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 195/75R16C, 215/75R16C and 235/60R17 as a planning band.
When does TPMS warn on a Ford Transit Custom?
Direct TPMS typically flags about 25% below placard — near 30 psi on this row. Fill to the sticker, not to the lamp.
Is the sidewall number correct on a Ford Transit Custom?
No. Sidewall PSI is a maximum. The Transit Custom placard is the operating target, near 35-45/45-65 psi.
