2.3 bar is not 23 psi. On this Full Custom 2.2-2.4 bar converts to about 32-35 psi. Use the table, not a guess. Size estimates on this page include 215/50R17, 245/40R18 and 205/55R16 — interpolated from the catalogue midpoint, not a second factory sticker.

Wenckstern Full Custom placard versus sidewall

The tyre-information placard on a Wenckstern Full Custom sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

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

215/50R17 is the first planning size here. 205/55R16 is usually the plus-size or LT step. Keep load index at or above original equipment.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
195/65R15	34	34	2.34	2.34	234	234	Very common compact
185/65R15	33	33	2.28	2.28	228	228	Small / older car
225/50R17	35	35	2.41	2.41	241	241	Touring 17-inch
225/45R17	35	35	2.41	2.41	241	241	Sport 17-inch

Load notes

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

How to set the Full Custom

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

Temperature drift

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

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

Wenckstern notes

No special Wenckstern exception: the Full Custom 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 Wenckstern Full Custom 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 Wenckstern sticker and this page disagree, the sticker wins.

Questions about this Full Custom

Front versus rear on the Wenckstern Full Custom?

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.

How often should I check a Full Custom?

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

Is the sidewall number correct on a Wenckstern Full Custom?

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

What is that in bar and kPa for the Full Custom?

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

What PSI if I plus-size toward 205/55R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/50R17, 245/40R18 and 205/55R16 as a planning band.
