Cold means the Gac Gonow Victor has stood at least three hours, or covered less than about a mile. Heat from a dual carriageway run is not the number you set. TPMS typically warns near 30 psi (about 25% below target). That is already a soft tyre, not a fill target.
Temperature and a cold gauge
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 |
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
If the Gac Gonow sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.
Estimated pressure by tyre size (LT265/70R17 and others)
LT265/70R17 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 |
|---|---|---|---|---|---|---|---|
| LT265/70R17 | 48 | 69 | 3.31 | 4.76 | 331 | 476 | LT 17-inch |
| 235/75R15 | 41 | 58 | 2.83 | 4 | 283 | 400 | Older compact truck |
| 255/65R17 | 43 | 60 | 2.96 | 4.14 | 296 | 414 | Highway 17-inch |
| 265/70R17 | 43 | 60 | 2.96 | 4.14 | 296 | 414 | Typical 17-inch load tyre |
| 275/65R18 | 43 | 61 | 2.96 | 4.21 | 296 | 421 | Plus-size 18-inch |
| 245/70R16 | 42 | 59 | 2.9 | 4.07 | 290 | 407 | Common 16-inch all-terrain |
| 285/70R17 | 44 | 62 | 3.03 | 4.27 | 303 | 427 | Wide all-terrain |
| LT245/75R16 | 48 | 67 | 3.31 | 4.62 | 331 | 462 | LT-metric, higher load |

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 | 40 psi / 2.76 bar | 56 psi / 3.86 bar |
| Motorway + luggage | 41 psi / 2.83 bar | 57 psi / 3.93 bar |
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
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.
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.
When does TPMS warn on a Gac Gonow Victor?
Direct TPMS typically flags about 25% below placard — near 30 psi on this row. Fill to the sticker, not to the lamp.
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 Gac Gonow Victor?
No. Sidewall PSI is a maximum. The Victor placard is the operating target, near 35-45/45-65 psi.
