Denza D9 bar chart (2.2-2.4 / 2.2-2.4)

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

European and UK handbooks usually quote bar. The Denza D9 catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). Size estimates on this page include 185/65R15, 215/55R16 and 215/50R17 — interpolated from the catalogue midpoint, not a second factory sticker.

Bar, PSI and kPa

Bar-led conversions around the Denza D9. 2.2-2.4 bar is not “32-35 divided by ten”.

2.28	33	228
2.31	33.5	231
2.41	35	241

Denza D9 placard versus sidewall

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

Estimated pressure by tyre size (185/65R15 and others)

185/65R15 is the first planning size here. 215/50R17 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
185/65R15	33	33	2.28	2.28	228	228	Small / older car
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
225/45R17	35	35	2.41	2.41	241	241	Sport 17-inch
195/65R15	34	34	2.34	2.34	234	234	Very common compact
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	38 psi / 2.62 bar

How to set the D9

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep D9 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 D9.

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

Denza notes

No special Denza exception: the D9 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 Denza D9 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 Denza sticker and this page disagree, the sticker wins.

Questions about this D9

Is the sidewall number correct on a Denza D9?

No. Sidewall PSI is a maximum. The D9 placard is the operating target, near 32-35/32-35 psi.

What PSI if I plus-size toward 215/50R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 185/65R15, 215/55R16 and 215/50R17 as a planning band.

What tyre pressure should a Denza D9 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.

Front versus rear on the Denza D9?

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 D9?

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