Recommended pressure means the vehicle placard, not the tyre sidewall. For a Gac Gonow Victor the catalogue proxy is 35-45/45-65 psi (2.4-3.1/3.1-4.5 bar). TPMS typically warns near 30 psi (about 25% below target). That is already a soft tyre, not a fill target.
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.
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)
If your Gac Gonow Victor no longer wears the OEM diameter, start at the row nearest 285/70R17 or LT265/70R17 and confirm with the tyre maker’s load table.

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 | 41 psi / 2.83 bar | 57 psi / 3.93 bar |
| Motorway + luggage | 42 psi / 2.9 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 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.
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.
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.
How often should I check a Victor?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
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.
