Recommended bar for a Tazzari EV Zero City

Drivetrain: front-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa

European and UK handbooks usually quote bar. The Tazzari EV Zero City catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). Size estimates on this page include 235/45R18, 205/55R16 and 245/40R18 — interpolated from the catalogue midpoint, not a second factory sticker. Battery mass on this {make} {model} makes a 4 psi-low tyre cost range as well as heat.

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

Planning cold pressures for sizes often seen on a passenger car. This Zero City sample opens with 235/45R18, then 205/55R16 and 245/40R18.

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
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	38 psi / 2.62 bar

How to set the Zero City

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

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 City 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 City 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 Zero City than nitrogen upsells.

Questions about this Zero City

How often should I check a Zero City?

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

What tyre pressure should a Tazzari EV Zero City 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 Zero City?

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 Zero City?

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

Front versus rear on the Tazzari EV Zero City?

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.
