Recommended pressure means the vehicle placard, not the tyre sidewall. For a Shelby F-150 Super Snake the catalogue proxy is 32-35/32-35 psi (2.2-2.4/2.2-2.4 bar). Size estimates on this page include 245/70R16, 255/65R17 and 265/70R17 — 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 265/70R17 are not filled like a Fiesta.

How to set the F-150 Super Snake

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep F-150 Super Snake 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.

Shelby F-150 Super Snake placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this F-150 Super Snake is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (245/70R16 and others)

245/70R16 is the first planning size here. 265/70R17 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
245/70R16	36	38	2.48	2.62	248	262	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	35 psi / 2.41 bar	36 psi / 2.48 bar
Payload / towing	36 psi / 2.48 bar	37 psi / 2.55 bar

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this F-150 Super Snake.

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

Shelby notes

No special Shelby exception: the F-150 Super Snake 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 Shelby F-150 Super Snake 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 F-150 Super Snake than nitrogen upsells.

Questions about this F-150 Super Snake

Is the sidewall number correct on a Shelby F-150 Super Snake?

No. Sidewall PSI is a maximum. The F-150 Super Snake placard is the operating target, near 32-35/32-35 psi.

What PSI if I plus-size toward 265/70R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/70R16, 255/65R17 and 265/70R17 as a planning band.

Front versus rear on the Shelby F-150 Super Snake?

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 Shelby F-150 Super Snake?

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 F-150 Super Snake?

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