A Volkswagen T5 Transporter run at sidewall-max (often 44–51 psi) is over-inflated for this light commercial. The operating PSI is 35-45/45-65. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Volkswagen tyre.
Volkswagen T5 Transporter placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this T5 Transporter is the pillar sticker, near 40/55 psi.

Estimated pressure by tyre size (285/70R17 and others)
If your Volkswagen T5 Transporter no longer wears the OEM diameter, start at the row nearest 285/70R17 or 265/70R17 and confirm with the tyre maker’s load table.

How to set the T5 Transporter
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep T5 Transporter 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.
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 | 58 psi / 4 bar |
Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 40 psi as a 20 °C baseline for this T5 Transporter.
| 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 |
Volkswagen notes
VW usually prints bar first (2.3, 2.5). Convert carefully: 2.3 bar is about 33 psi, not 23. Golf, Passat and Tiguan stickers are not interchangeable.
Spare and inflator kit
A matching full-size spare on the Volkswagen T5 Transporter 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.
A cheap gauge and a monthly habit will do more for this T5 Transporter than nitrogen upsells.

Questions about this T5 Transporter
What tyre pressure should a Volkswagen T5 Transporter 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.
What is that in bar and kPa for the T5 Transporter?
Mid-points are about 2.76 bar (276 kPa) front and 3.79 bar (379 kPa) rear.
Is the sidewall number correct on a Volkswagen T5 Transporter?
No. Sidewall PSI is a maximum. The T5 Transporter placard is the operating target, near 35-45/45-65 psi.
Front versus rear on the Volkswagen T5 Transporter?
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.
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.
