A 3 psi miss on one front corner of this Colorado shows up as a wander before the TPMS lamp bothers you. Target 34 psi (2.31 bar) cold. Under-inflation cooks the shoulders of a Colorado; over-inflation wears the centre rib and bangs every cat’s eye. Commercial and load-biased bodies like this pickup / double-cab often need a higher rear; LT or C-type sizes such as 255/65R17 are not filled like a Fiesta.
Chevrolet Colorado placard versus sidewall
If the Chevrolet sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.
Estimated pressure by tyre size (285/70R17 and others)
If your Chevrolet Colorado 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.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 285/70R17 | 38 | — | 2.62 | — | 262 | — | Wide all-terrain |
| LT265/70R17 | 42 | — | 2.9 | — | 290 | — | LT 17-inch |
| 255/65R17 | 37 | — | 2.55 | — | 255 | — | Highway 17-inch |
| 235/75R15 | 35 | — | 2.41 | — | 241 | — | Older compact truck |
| LT245/75R16 | 42 | — | 2.9 | — | 290 | — | LT-metric, higher load |
| 265/70R17 | 37 | — | 2.55 | — | 255 | — | Typical 17-inch load tyre |
| 275/65R18 | 37 | — | 2.55 | — | 255 | — | Plus-size 18-inch |
| 245/70R16 | 36 | — | 2.48 | — | 248 | — | Common 16-inch all-terrain |
Pressure against load
Load moves the rear of a pickup / double-cab first. If the factory placard already has a “laden” column, use that instead of these sketches.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only | 34 psi / 2.34 bar | 34 psi / 2.34 bar |
| Full occupancy | 34 psi / 2.34 bar | 35 psi / 2.41 bar |
| Payload / towing | 35 psi / 2.41 bar | 37 psi / 2.55 bar |
Steering feel on the Colorado lives on this axle. Do not drop front pressure to “soften” a plus-size 255/65R17; you will roll the sidewall in a roundabout.
How to set the Colorado
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Colorado numbers in your head.
- Add air in short bursts toward 34 psi (2.31 bar) front and 34 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.

Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Colorado.
| Ambient | Gauge (front mid) | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 31 psi | 2.14 bar | 214 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 32 psi | 2.21 bar | 221 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 33 psi | 2.28 bar | 228 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 34 psi | 2.34 bar | 234 kPa | Baseline |
| 30 °C | 36 psi | 2.48 bar | 248 kPa | Do not bleed a hot tyre |
| 38 °C (heatwave tarmac) | 37 psi | 2.55 bar | 255 kPa | Do not bleed a hot tyre |
Chevrolet notes
No special Chevrolet exception: the Colorado 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 Chevrolet Colorado usually follows the higher axle (often the rear, near 32-35 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 Chevrolet sticker and this page disagree, the sticker wins.

Questions about this Colorado
What is that in bar and kPa for the Colorado?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
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 Colorado?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
When does TPMS warn on a Chevrolet Colorado?
Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.
What tyre pressure should a Chevrolet Colorado use?
Catalogue reference is 32-35 psi front and 32-35 psi rear (2.2-2.4 / 2.2-2.4 bar), cold. Confirm on the door-pillar placard.
