A front-wheel drive Tazzari EV Zero EM2 still wants even corners. 2.2-2.4 vs 2.2-2.4 is an axle split, not a left-right split. Under-inflation cooks the shoulders of a Zero EM2; 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.

Estimated pressure by tyre size (255/40R19 and others)

Planning cold pressures for sizes often seen on a passenger car. This Zero EM2 sample opens with 255/40R19, then 235/45R18 and 225/45R17.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
255/40R19	37	37	2.55	2.55	255	255	EV 19-inch aero wheel
235/45R18	36	36	2.48	2.48	248	248	Common EV 18-inch

215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
195/65R15	34	34	2.34	2.34	234	234	Very common compact

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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	38 psi / 2.62 bar

How to set the Zero EM2

Park the Tazzari EV Zero EM2 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 Zero EM2 is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Zero EM2.

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 notes

No special Tazzari EV exception: the Zero EM2 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 Tazzari EV Zero EM2 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.

Keep the Tazzari EV Zero EM2 on the printed band; use 255/40R19 and 225/45R17 only as a map for non-OEM wheels.

Questions about this Zero EM2

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.

When does TPMS warn on a Tazzari EV Zero EM2?

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

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 255/40R19, 235/45R18 and 225/45R17 as a planning band.

Front versus rear on the Tazzari EV Zero EM2?

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 Zero EM2 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.
