psi front

2.31 bar · 231 kPa at the steering axle

The front axle of a Aiways U6 Ion 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 205/60R16, 245/40R18 and 195/65R15 — interpolated from the catalogue midpoint, not a second factory sticker.

Aiways U6 Ion placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this U6 Ion is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (205/60R16 and others)

Planning cold pressures for sizes often seen on a passenger car. This U6 Ion sample opens with 205/60R16, then 245/40R18 and 195/65R15.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
205/60R16	34	—	2.34	—	234	—	Taller 16-inch
245/40R18	36	—	2.48	—	248	—	Wide touring 18-inch
195/65R15	34	—	2.34	—	234	—	Very common compact
185/65R15	33	—	2.28	—	228	—	Small / older car
225/40R18	36	—	2.48	—	248	—	Low-profile 18-inch
225/45R17	35	—	2.41	—	241	—	Sport 17-inch
205/55R16	34	—	2.34	—	234	—	Typical mid-compact OEM
215/55R16	34	—	2.34	—	234	—	Slightly wider 16-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	37 psi / 2.55 bar

Steering feel on the U6 Ion lives on this axle. Do not drop front pressure to “soften” a plus-size 195/65R15; you will roll the sidewall in a roundabout.

How to set the U6 Ion

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep U6 Ion 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 U6 Ion.

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

Aiways notes

No special Aiways exception: the U6 Ion 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 Aiways U6 Ion 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 U6 Ion than nitrogen upsells.

Questions about this U6 Ion

What is that in bar and kPa for the U6 Ion?

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

Is the sidewall number correct on a Aiways U6 Ion?

No. Sidewall PSI is a maximum. The U6 Ion placard is the operating target, near 32-35/32-35 psi.

What PSI if I plus-size toward 195/65R15?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 205/60R16, 245/40R18 and 195/65R15 as a planning band.

When does TPMS warn on a Aiways U6 Ion?

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

What tyre pressure should a Aiways U6 Ion 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.
