European and UK handbooks usually quote bar. The Toyota Tundra catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). Size estimates on this page include 275/65R18, 235/75R15 and 245/70R16 — 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 245/70R16 are not filled like a Fiesta.

Estimated pressure by tyre size (275/65R18 and others)

Planning cold pressures for sizes often seen on a pickup / double-cab. This Tundra sample opens with 275/65R18, then 235/75R15 and 245/70R16.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
275/65R18	37	40	2.55	2.76	255	276	Plus-size 18-inch
235/75R15	35	37	2.41	2.55	241	255	Older compact truck
245/70R16	36	38	2.48	2.62	248	262	Common 16-inch all-terrain
LT245/75R16	42	46	2.9	3.17	290	317	LT-metric, higher load
285/70R17	38	41	2.62	2.83	262	283	Wide all-terrain

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	34 psi / 2.34 bar	35 psi / 2.41 bar
Payload / towing	35 psi / 2.41 bar	37 psi / 2.55 bar

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.

Temperature drift

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

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

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.

How often should I check a Tundra?

Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.

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.

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.

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.
