PSI is the Imperial reading most UK motorists still see on garage hoses. For the Renault Master the catalogue row is 35-45 psi front and 45-65 psi rear. Size estimates on this page include 215/75R16C, 225/65R16 and 195/75R16C — interpolated from the catalogue midpoint, not a second factory sticker. Commercial and load-biased bodies like this van often need a higher rear; LT or C-type sizes such as 195/75R16C are not filled like a Fiesta.
Renault Master placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this Master is the pillar sticker, near 40/55 psi.
PSI, bar and kPa
PSI-led conversions for the Renault Master band (35-45 / 45-65).
| PSI | Bar | kPa |
|---|---|---|

Estimated pressure by tyre size (215/75R16C and others)
215/75R16C is the first planning size here. 195/75R16C is usually the plus-size or LT step. Keep load index at or above original equipment.

How to set the Master
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Master 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 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 | 57 psi / 3.93 bar |
Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 40 psi as a 20 °C baseline for this Master.
| 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 |
Renault notes
Renault vans (Trafic, Master) live in a commercial band. Clios do not.
Spare and inflator kit
A matching full-size spare on the Renault Master 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 Renault sticker and this page disagree, the sticker wins.

Questions about this Master
Front versus rear on the Renault Master?
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.
Is the sidewall number correct on a Renault Master?
No. Sidewall PSI is a maximum. The Master placard is the operating target, near 35-45/45-65 psi.
How often should I check a Master?
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 Master?
Mid-points are about 2.76 bar (276 kPa) front and 3.79 bar (379 kPa) rear.
