psi front

2.31 bar · 231 kPa at the steering axle

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

The front axle of a SGS St. Tropez Cabrio Limousine steers and, on front-wheel drive cars, often pulls as well. Catalogue front pressure is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include 215/50R17, 225/45R17 and 225/40R18 — interpolated from the catalogue midpoint, not a second factory sticker.

SGS St. Tropez Cabrio Limousine placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this St. Tropez Cabrio Limousine is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (215/50R17 and others)

Planning cold pressures for sizes often seen on a passenger car. This St. Tropez Cabrio Limousine sample opens with 215/50R17, then 225/45R17 and 225/40R18.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/50R17	35	—	2.41	—	241	—	Plus-size 17-inch
225/45R17	35	—	2.41	—	241	—	Sport 17-inch
225/40R18	36	—	2.48	—	248	—	Low-profile 18-inch
185/65R15	33	—	2.28	—	228	—	Small / older car
205/55R16	34	—	2.34	—	234	—	Typical mid-compact OEM
215/55R16	34	—	2.34	—	234	—	Slightly wider 16-inch
205/60R16	34	—	2.34	—	234	—	Taller 16-inch
195/65R15	34	—	2.34	—	234	—	Very common compact

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

Steering feel on the St. Tropez Cabrio Limousine lives on this axle. Do not drop front pressure to “soften” a plus-size 225/40R18; you will roll the sidewall in a roundabout.

How to set the St. Tropez Cabrio Limousine

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep St. Tropez Cabrio Limousine 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.

Temperature drift

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

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

SGS notes

No special SGS exception: the St. Tropez Cabrio Limousine 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 SGS St. Tropez Cabrio Limousine 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 SGS sticker and this page disagree, the sticker wins.

Questions about this St. Tropez Cabrio Limousine

Front versus rear on the SGS St. Tropez Cabrio Limousine?

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.

Is the sidewall number correct on a SGS St. Tropez Cabrio Limousine?

No. Sidewall PSI is a maximum. The St. Tropez Cabrio Limousine placard is the operating target, near 32-35/32-35 psi.

When does TPMS warn on a SGS St. Tropez Cabrio Limousine?

Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.

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 215/50R17, 225/45R17 and 225/40R18 as a planning band.

What is that in bar and kPa for the St. Tropez Cabrio Limousine?

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