Cold means the Toyota Tundra 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. Size estimates on this page include 285/70R17, LT245/75R16 and 255/65R17 — interpolated from the catalogue midpoint, not a second factory sticker. 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.
Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Tundra.
| 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 |
How to set the Tundra
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Tundra 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.
Toyota Tundra placard versus sidewall
The tyre-information placard on a Toyota Tundra sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 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 | 38 | 41 | 2.62 | 2.83 | 262 | 283 | Wide all-terrain |
| LT245/75R16 | 42 | 46 | 2.9 | 3.17 | 290 | 317 | LT-metric, higher load |
| 255/65R17 | 37 | 39 | 2.55 | 2.69 | 255 | 269 | Highway 17-inch |
| 245/70R16 | 36 | 38 | 2.48 | 2.62 | 248 | 262 | Common 16-inch all-terrain |
| 235/75R15 | 35 | 37 | 2.41 | 2.55 | 241 | 255 | Older compact truck |
| 265/70R17 | 37 | 39 | 2.55 | 2.69 | 255 | 269 | Typical 17-inch load tyre |
| LT265/70R17 | 42 | 48 | 2.9 | 3.31 | 290 | 331 | LT 17-inch |

Load notes
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 | 35 psi / 2.41 bar | 36 psi / 2.48 bar |
| Payload / towing | 36 psi / 2.48 bar | 38 psi / 2.62 bar |
Toyota notes
Toyota trucks print front and rear separately more often than cars. A roof box on a RAV4 is a load condition, not a forum “add 5 psi” rule.
Spare and inflator kit
A matching full-size spare on the Toyota Tundra 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.
A cheap gauge and a monthly habit will do more for this Tundra than nitrogen upsells.

Questions about this Tundra
Front versus rear on the Toyota Tundra?
This row is 32-35 F / 32-35 R. Even when they match, a laden rear can justify a higher number if the sticker prints one.
When does TPMS warn on a Toyota Tundra?
Direct TPMS typically flags about 25% below placard — near 25 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.
What is that in bar and kPa for the Tundra?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
Is the sidewall number correct on a Toyota Tundra?
No. Sidewall PSI is a maximum. The Tundra placard is the operating target, near 32-35/32-35 psi.
