This front-wheel drive passenger car is filed here with a working range of 32-35/32-35 psi. The pillar sticker on your VIN still overrides the website. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Skywell tyre.

How to set the ET5

Park the Skywell ET5 for at least three hours (cold tyres).
Use a calibrated gauge, not the only meter on a forecourt hose.
Set the placard for that axle — about 32-35 psi / 2.2-2.4 bar front and 32-35 psi / 2.2-2.4 bar rear on this catalogue row.
Recheck all four. A 2 psi miss on a front-wheel drive ET5 is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	37 psi / 2.55 bar

Spare and inflator kit

A matching full-size spare on the Skywell ET5 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.

Skywell notes

No special Skywell exception: the ET5 uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.

Skywell ET5 placard versus sidewall

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

Temperature and a cold gauge

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this ET5.

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

Estimated pressure by tyre size (225/40R18 and others)

If your Skywell ET5 no longer wears the OEM diameter, start at the row nearest 225/40R18 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
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
225/50R17	35	35	2.41	2.41	241	241	Touring 17-inch
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
195/65R15	34	34	2.34	2.34	234	234	Very common compact
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
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch

PSI, bar and kPa

1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the ET5: 34 psi = 2.31 bar = 231 kPa.

PSI	Bar	kPa
30	2.07	207
32	2.21	221
33	2.28	228
33.5	2.31	231
35	2.41	241
36	2.48	248
38	2.62	262
40	2.76	276
44	3.03	303
50	3.45	345
60	4.14	414

Keep the Skywell ET5 on the printed band; use 225/40R18 and 225/50R17 only as a map for non-OEM wheels.

Questions about this ET5

When does TPMS warn on a Skywell ET5?

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

Front versus rear on the Skywell ET5?

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.

Should I bleed pressure after a motorway run?

No. Heat raises the gauge. Set cold only. Bleeding a hot tyre leaves it low the next morning.

Is the sidewall number correct on a Skywell ET5?

No. Sidewall PSI is a maximum. The ET5 placard is the operating target, near 32-35/32-35 psi.

How often should I check a ET5?

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