Recommended pressure means the vehicle placard, not the tyre sidewall. For a Bentley Continental GTC the catalogue proxy is 32-35/32-35 psi (2.2-2.4/2.2-2.4 bar). Size estimates on this page include 275/30R19, 225/45R17 and 225/40R18 — interpolated from the catalogue midpoint, not a second factory sticker.

How to set the Continental GTC

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Continental GTC 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.

If the Bentley sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

Estimated pressure by tyre size (275/30R19 and others)

If your Bentley Continental GTC no longer wears the OEM diameter, start at the row nearest 275/30R19 or 225/45R17 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
275/30R19	36	37	2.48	2.55	248	255	Rear 19-inch

Pressure against load

Load moves the rear of a passenger car 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
Motorway + luggage	35 psi / 2.41 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 Continental GTC.

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

Bentley notes

No special Bentley exception: the Continental GTC 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 Bentley Continental GTC 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 Continental GTC than nitrogen upsells.

Questions about this Continental GTC

Is the sidewall number correct on a Bentley Continental GTC?

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

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 PSI if I plus-size toward 225/40R18?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 275/30R19, 225/45R17 and 225/40R18 as a planning band.

What is that in bar and kPa for the Continental GTC?

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

How often should I check a Continental GTC?

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