Cold means the Ford Transit Bus has stood at least three hours, or covered less than about a mile. Heat from a dual carriageway run is not the number you set. TPMS typically warns near 30 psi (about 25% below target). That is already a soft tyre, not a fill target. Commercial and load-biased bodies like this van often need a higher rear; LT or C-type sizes such as 225/75R16 are not filled like a Fiesta.
Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 40 psi as a 20 °C baseline for this Transit Bus.
| 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 |
How to set the Transit Bus
- Park the Ford Transit Bus 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 Bus is enough to feel a pull.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.
Ford Transit Bus placard versus sidewall
The tyre-information placard on a Ford Transit Bus sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 35-45 / 45-65 psi.
Estimated pressure by tyre size (215/75R16C and others)
If your Ford Transit Bus no longer wears the OEM diameter, start at the row nearest 215/75R16C or 235/65R16 and confirm with the tyre maker’s load table.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 215/75R16C | 45 | 64 | 3.1 | 4.41 | 310 | 441 | C-type 215 |

Load notes
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 | 40 psi / 2.76 bar | 56 psi / 3.86 bar |
| Payload / towing | 41 psi / 2.83 bar | 58 psi / 4 bar |
Ford notes
Ford UK placards on the Transit Bus 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 Bus 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 Bus on the printed band; use 215/75R16C and 225/75R16 only as a map for non-OEM wheels.

Questions about this Transit Bus
Is the sidewall number correct on a Ford Transit Bus?
No. Sidewall PSI is a maximum. The Transit Bus placard is the operating target, near 35-45/45-65 psi.
Front versus rear on the Ford Transit Bus?
This row is 35-45 F / 45-65 R. Even when they match, a laden rear can justify a higher number if the sticker prints one.
When does TPMS warn on a Ford Transit Bus?
Direct TPMS typically flags about 25% below placard — near 30 psi on this row. Fill to the sticker, not to the lamp.
What tyre pressure should a Ford Transit Bus 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 Bus?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
