Cold means the BAIC Senova X25 has stood at least three hours, or covered less than about a mile. Heat from a dual carriageway run is not the number you set. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

Temperature and a cold gauge

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Senova X25.

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

How to set the Senova X25

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Senova X25 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.

BAIC Senova X25 placard versus sidewall

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

Estimated pressure by tyre size (215/55R16 and others)

If your BAIC Senova X25 no longer wears the OEM diameter, start at the row nearest 215/55R16 or 205/60R16 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
205/60R16	34	34	2.34	2.34	234	234	Taller 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
185/65R15	33	33	2.28	2.28	228	228	Small / older car
245/40R18	36	36	2.48	2.48	248	248	Wide touring 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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	36 psi / 2.48 bar

BAIC notes

No special BAIC exception: the Senova X25 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 BAIC Senova X25 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 BAIC sticker and this page disagree, the sticker wins.

Questions about this Senova X25

Front versus rear on the BAIC Senova X25?

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.

What is that in bar and kPa for the Senova X25?

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

When does TPMS warn on a BAIC Senova X25?

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

Is the sidewall number correct on a BAIC Senova X25?

No. Sidewall PSI is a maximum. The Senova X25 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 215/55R16, 205/60R16 and 215/50R17 as a planning band.
