Treat this page as a map of the J5 band. The legal setpoint is the printed door-pillar label for your VIN. Under-inflation cooks the shoulders of a J5; over-inflation wears the centre rib and bangs every cat’s eye.

How to set the J5

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep J5 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.

Jaecoo J5 placard versus sidewall

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

Estimated pressure by tyre size (195/65R15 and others)

195/65R15 is the first planning size here. 205/60R16 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
195/65R15	34	34	2.34	2.34	234	234	Very common compact
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
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
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	36 psi / 2.48 bar

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this J5.

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

Jaecoo notes

No special Jaecoo exception: the J5 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 Jaecoo J5 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.

A cheap gauge and a monthly habit will do more for this J5 than nitrogen upsells.

Questions about this J5

What tyre pressure should a Jaecoo J5 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.

When does TPMS warn on a Jaecoo J5?

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

What is that in bar and kPa for the J5?

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

Is the sidewall number correct on a Jaecoo J5?

No. Sidewall PSI is a maximum. The J5 placard is the operating target, near 32-35/32-35 psi.

Front versus rear on the Jaecoo J5?

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.
