Recommended pressure means the vehicle placard, not the tyre sidewall. For a Giotti Victoria Gladiator the catalogue proxy is 32-35/32-35 psi (2.2-2.4/2.2-2.4 bar). TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target. 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.

How to set the Gladiator

Park the Giotti Victoria Gladiator for at least three hours (cold tyres).
Use a calibrated gauge, not the only meter on a forecourt hose.
Set the placard for that axle — about 32-35 psi / 2.2-2.4 bar front and 32-35 psi / 2.2-2.4 bar rear on this catalogue row.
Recheck all four. A 2 psi miss on a rear-wheel drive Gladiator is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Estimated pressure by tyre size (235/75R15 and others)

Planning cold pressures for sizes often seen on a pickup / double-cab. This Gladiator sample opens with 235/75R15, then 285/70R17 and 255/65R17.

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	36 psi / 2.48 bar

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Gladiator.

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

Giotti Victoria notes

No special Giotti Victoria exception: the Gladiator 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 Giotti Victoria Gladiator 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 Giotti Victoria sticker and this page disagree, the sticker wins.

Questions about this Gladiator

Is the sidewall number correct on a Giotti Victoria Gladiator?

No. Sidewall PSI is a maximum. The Gladiator placard is the operating target, near 32-35/32-35 psi.

When does TPMS warn on a Giotti Victoria Gladiator?

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.

How often should I check a Gladiator?

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

Front versus rear on the Giotti Victoria Gladiator?

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.
