35-45 psi F · 45-65 psi R · 2.4-3.1 / 3.1-4.5 bar · 276/379 kPa
Loaded Victor rears often need the sticker’s second column, not a copy of the front 35-45 psi figure. Under-inflation cooks the shoulders of a Victor; over-inflation wears the centre rib and bangs every cat’s eye.
Gac Gonow Victor placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this Victor is the pillar sticker, near 40/55 psi.
Estimated pressure by tyre size (285/70R17 and others)
285/70R17 is the first planning size here. 255/65R17 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 |
|---|---|---|---|---|---|---|---|
| 285/70R17 | — | 62 | — | 4.27 | — | 427 | Wide all-terrain |
| LT265/70R17 | — | 69 | — | 4.76 | — | 476 | LT 17-inch |
| 255/65R17 | — | 60 | — | 4.14 | — | 414 | Highway 17-inch |
| LT245/75R16 | — | 67 | — | 4.62 | — | 462 | LT-metric, higher load |
| 235/75R15 | — | 58 | — | 4 | — | 400 | Older compact truck |
| 245/70R16 | — | 59 | — | 4.07 | — | 407 | Common 16-inch all-terrain |
| 275/65R18 | — | 61 | — | 4.21 | — | 421 | Plus-size 18-inch |

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 |
A family light commercial with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this Victor.
How to set the Victor
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Victor 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.
PSI, bar and kPa

Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 40 psi as a 20 °C baseline for this Victor.
| 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 |
Gac Gonow notes
No special Gac Gonow exception: the Victor 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 Gac Gonow Victor 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 Gac Gonow sticker and this page disagree, the sticker wins.

Questions about this Victor
What is that in bar and kPa for the Victor?
Mid-points are about 2.76 bar (276 kPa) front and 3.79 bar (379 kPa) rear.
What tyre pressure should a Gac Gonow Victor 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 PSI if I plus-size toward 255/65R17?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 285/70R17, LT265/70R17 and 255/65R17 as a planning band.
Is the sidewall number correct on a Gac Gonow Victor?
No. Sidewall PSI is a maximum. The Victor placard is the operating target, near 35-45/45-65 psi.
Front versus rear on the Gac Gonow Victor?
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.
