Loaded EM1 Citysport rears often need the sticker’s second column, not a copy of the front 32-35 psi figure. 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.
Tazzari EV EM1 Citysport placard versus sidewall
The tyre-information placard on a Tazzari EV EM1 Citysport sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.
Estimated pressure by tyre size (205/60R16 and others)
Planning cold pressures for sizes often seen on a passenger car. This EM1 Citysport sample opens with 205/60R16, then 205/55R16 and 255/40R19.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 205/60R16 | — | 34 | — | 2.34 | — | 234 | Taller 16-inch |
| 205/55R16 | — | 34 | — | 2.34 | — | 234 | Typical mid-compact OEM |
| 255/40R19 | — | 37 | — | 2.55 | — | 255 | EV 19-inch aero wheel |
| 195/65R15 | — | 34 | — | 2.34 | — | 234 | Very common compact |
| 245/40R18 | — | 36 | — | 2.48 | — | 248 | Wide touring 18-inch |
| 215/50R17 | — | 35 | — | 2.41 | — | 241 | Plus-size 17-inch |
| 185/65R15 | — | 33 | — | 2.28 | — | 228 | Small / older car |
| 225/50R17 | — | 35 | — | 2.41 | — | 241 | Touring 17-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 | 37 psi / 2.55 bar |
A family passenger car with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this EM1 Citysport.
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.

Temperature drift
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 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.
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.
If the Tazzari EV sticker and this page disagree, the sticker wins.

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.
How often should I check a EM1 Citysport?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
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.
What PSI if I plus-size toward 255/40R19?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 205/60R16, 205/55R16 and 255/40R19 as a planning band.
What is that in bar and kPa for the EM1 Citysport?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
