On a Tazzari EV EM1 Citysport the useful pair is 34 psi (2.31 bar) up front and 34 psi (2.31 bar) at the back, mid-range. Under-inflation cooks the shoulders of a EM1 Citysport; over-inflation wears the centre rib and bangs every cat’s eye. Battery mass on this {make} {model} makes a 4 psi-low tyre cost range as well as heat.

Spare and inflator kit

A matching full-size spare on the Tazzari EV EM1 Citysport 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.

How to set the EM1 Citysport

Park the Tazzari EV EM1 Citysport 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 EM1 Citysport is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Tazzari EV notes

No special Tazzari EV exception: the EM1 Citysport uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.

Estimated pressure by tyre size (235/45R18 and others)

If your Tazzari EV EM1 Citysport no longer wears the OEM diameter, start at the row nearest 235/45R18 or 215/55R16 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
235/45R18	36	36	2.48	2.48	248	248	Common EV 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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	38 psi / 2.62 bar

Temperature and a cold gauge

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this EM1 Citysport.

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

Tazzari EV EM1 Citysport placard versus sidewall

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

PSI, bar and kPa

1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the EM1 Citysport: 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

A cheap gauge and a monthly habit will do more for this EM1 Citysport than nitrogen upsells.

Questions about this EM1 Citysport

Front versus rear on the Tazzari EV EM1 Citysport?

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 tyre pressure should a Tazzari EV EM1 Citysport 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 Tazzari EV EM1 Citysport?

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 Tazzari EV EM1 Citysport?

No. Sidewall PSI is a maximum. The EM1 Citysport placard is the operating target, near 32-35/32-35 psi.

What PSI if I plus-size toward 225/45R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 235/45R18, 215/55R16 and 225/45R17 as a planning band.
