Cold tyre pressure for a Shelby F-150 Super Snake

UK winter mornings will show a lower gauge on this F-150 Super Snake without a puncture. Set 34/34 psi at ~20 °C equivalent, not after a motorway blast. Under-inflation cooks the shoulders of a F-150 Super Snake; 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 245/70R16 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 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

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.

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

Planning cold pressures for sizes often seen on a pickup / double-cab. This F-150 Super Snake 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

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	36 psi / 2.48 bar

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.

Keep the Shelby F-150 Super Snake on the printed band; use 275/65R18 and 245/70R16 only as a map for non-OEM wheels.

Questions about this F-150 Super Snake

What is that in bar and kPa for the F-150 Super Snake?

Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.

What tyre pressure should a Shelby F-150 Super Snake 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.

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.

What PSI if I plus-size toward 245/70R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 275/65R18, 235/75R15 and 245/70R16 as a planning band.

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.
