Bentley · Continental GTC · Rear

Bentley Continental GTC rear tyres: 32-35 psi / 2.2-2.4 bar

Drivetrain: rear-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

psi rear

2.31 bar · 231 kPa at the rear axle

32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa

Loaded Continental GTC rears often need the sticker’s second column, not a copy of the front 32-35 psi figure. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Bentley tyre.

Bentley Continental GTC placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this Continental GTC is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (255/35R18 and others)

If your Bentley Continental GTC no longer wears the OEM diameter, start at the row nearest 255/35R18 or 275/35R18 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
255/35R18	—	36	—	2.48	—	248	Rear stagger 18-inch
275/35R18	—	37	—	2.55	—	255	Wide rear
275/30R19	—	37	—	2.55	—	255	Rear 19-inch
245/40R18	—	36	—	2.48	—	248	Square-ish sport
225/40R18	—	35	—	2.41	—	241	Front 18-inch
225/45R17	—	35	—	2.41	—	241	Front sport size
255/40R17	—	36	—	2.48	—	248	Rear stagger 17-inch
235/35R19	—	36	—	2.48	—	248	Front 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	38 psi / 2.62 bar

A family passenger car with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this Continental GTC.

How to set the Continental GTC

Park the Bentley Continental GTC 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 Continental GTC is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

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.

Keep the Bentley Continental GTC on the printed band; use 255/35R18 and 275/30R19 only as a map for non-OEM wheels.

Questions about this Continental GTC

What PSI if I plus-size toward 275/30R19?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 255/35R18, 275/35R18 and 275/30R19 as a planning band.

What tyre pressure should a Bentley Continental GTC 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 Continental GTC?

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

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.

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.
