35-45 psi F · 45-65 psi R · 2.4-3.1 / 3.1-4.5 bar · 276/379 kPa
The Dangel Jumper catalogue band is 35-45 psi front and 45-65 psi rear — 2.4-3.1 / 3.1-4.5 bar, or about 276 / 379 kPa — measured cold. TPMS typically warns near 30 psi (about 25% below target). That is already a soft tyre, not a fill target.
Pressure against load
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 | 40 psi / 2.76 bar | 56 psi / 3.86 bar |
| Motorway + luggage | 41 psi / 2.83 bar | 58 psi / 4 bar |
PSI, bar and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the Jumper: 40 psi = 2.76 bar = 276 kPa.
| PSI | Bar | kPa |
|---|---|---|
| 35 | 2.41 | 241 |
| 36 | 2.48 | 248 |
| 38 | 2.62 | 262 |
| 40 | 2.76 | 276 |
| 44 | 3.03 | 303 |
| 45 | 3.10 | 310 |
| 50 | 3.45 | 345 |
| 55 | 3.79 | 379 |
| 60 | 4.14 | 414 |
| 65 | 4.48 | 448 |
Spare and inflator kit
A matching full-size spare on the Dangel Jumper 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.
How to set the Jumper
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Jumper numbers in your head.
- Add air in short bursts toward 40 psi (2.76 bar) front and 55 psi rear.
- If one corner is 4 psi down, hunt for a nail before you blame the weather.
- Log date, ambient temperature and the four readings.
Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 40 psi as a 20 °C baseline for this Jumper.
| 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 |
Dangel Jumper placard versus sidewall
The tyre-information placard on a Dangel Jumper 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 (265/70R17 and others)
Planning cold pressures for sizes often seen on a light commercial. This Jumper sample opens with 265/70R17, then 245/70R16 and 235/75R15.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 265/70R17 | 43 | 60 | 2.96 | 4.14 | 296 | 414 | Typical 17-inch load tyre |
| 245/70R16 | 42 | 59 | 2.9 | 4.07 | 290 | 407 | Common 16-inch all-terrain |

| LT265/70R17 | 48 | 69 | 3.31 | 4.76 | 331 | 476 | LT 17-inch |
| 275/65R18 | 43 | 61 | 2.96 | 4.21 | 296 | 421 | Plus-size 18-inch |
| 255/65R17 | 43 | 60 | 2.96 | 4.14 | 296 | 414 | Highway 17-inch |
| LT245/75R16 | 48 | 67 | 3.31 | 4.62 | 331 | 462 | LT-metric, higher load |

Dangel notes
No special Dangel exception: the Jumper uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.
If the Dangel sticker and this page disagree, the sticker wins.

Questions about this Jumper
What tyre pressure should a Dangel Jumper 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.
Is the sidewall number correct on a Dangel Jumper?
No. Sidewall PSI is a maximum. The Jumper placard is the operating target, near 35-45/45-65 psi.
Front versus rear on the Dangel Jumper?
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 Dangel Jumper?
Direct TPMS typically flags about 25% below placard — near 30 psi on this row. Fill to the sticker, not to the lamp.
What PSI if I plus-size toward 235/75R15?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 265/70R17, 245/70R16 and 235/75R15 as a planning band.
