Cold means the DAF 435 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.
Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 40 psi as a 20 °C baseline for this 435.
| 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 435
- Park the DAF 435 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 435 is enough to feel a pull.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.
DAF 435 placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this 435 is the pillar sticker, near 40/55 psi.
Estimated pressure by tyre size (235/75R15 and others)
235/75R15 is the first planning size here. 265/70R17 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 |
|---|---|---|---|---|---|---|---|
| 235/75R15 | 41 | 58 | 2.83 | 4 | 283 | 400 | Older compact truck |
| LT265/70R17 | 48 | 69 | 3.31 | 4.76 | 331 | 476 | LT 17-inch |
| 265/70R17 | 43 | 60 | 2.96 | 4.14 | 296 | 414 | Typical 17-inch load tyre |
| LT245/75R16 | 48 | 67 | 3.31 | 4.62 | 331 | 462 | LT-metric, higher load |
| 255/65R17 | 43 | 60 | 2.96 | 4.14 | 296 | 414 | Highway 17-inch |
| 275/65R18 | 43 | 61 | 2.96 | 4.21 | 296 | 421 | Plus-size 18-inch |
| 245/70R16 | 42 | 59 | 2.9 | 4.07 | 290 | 407 | Common 16-inch all-terrain |
| 285/70R17 | 44 | 62 | 3.03 | 4.27 | 303 | 427 | Wide all-terrain |

Load notes
Load moves the rear of a light commercial 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 |
| Motorway + luggage | 42 psi / 2.9 bar | 59 psi / 4.07 bar |
DAF notes
No special DAF exception: the 435 uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.
Spare and inflator kit
A matching full-size spare on the DAF 435 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.
If the DAF sticker and this page disagree, the sticker wins.

Questions about this 435
Front versus rear on the DAF 435?
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.
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, LT265/70R17 and 265/70R17 as a planning band.
Is the sidewall number correct on a DAF 435?
No. Sidewall PSI is a maximum. The 435 placard is the operating target, near 35-45/45-65 psi.
How often should I check a 435?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
What is that in bar and kPa for the 435?
Mid-points are about 2.76 bar (276 kPa) front and 3.79 bar (379 kPa) rear.
