Rear axle PSI and bar on the Iso Rivolta Fidia

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

psi rear

2.31 bar · 231 kPa at the rear axle

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

Loaded Fidia rears often need the sticker’s second column, not a copy of the front 32-35 psi figure. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Iso Rivolta tyre.

Iso Rivolta Fidia placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this Fidia is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (215/55R16 and others)

215/55R16 is the first planning size here. 205/60R16 is usually the plus-size or LT step. Keep load index at or above original equipment.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/55R16	—	35	—	2.41	—	241	Slightly wider 16-inch
225/40R18	—	36	—	2.48	—	248	Low-profile 18-inch
205/60R16	—	34	—	2.34	—	234	Taller 16-inch
245/40R18	—	36	—	2.48	—	248	Wide touring 18-inch
225/45R17	—	35	—	2.41	—	241	Sport 17-inch
205/55R16	—	34	—	2.34	—	234	Typical mid-compact OEM
185/65R15	—	33	—	2.28	—	228	Small / older car
195/65R15	—	34	—	2.34	—	234	Very common compact

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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	36 psi / 2.48 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 Fidia.

How to set the Fidia

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

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

Iso Rivolta notes

No special Iso Rivolta exception: the Fidia 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 Iso Rivolta Fidia 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 Iso Rivolta sticker and this page disagree, the sticker wins.

Questions about this Fidia

Front versus rear on the Iso Rivolta Fidia?

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.

What tyre pressure should a Iso Rivolta Fidia 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.

What is that in bar and kPa for the Fidia?

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

What PSI if I plus-size toward 205/60R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/55R16, 225/40R18 and 205/60R16 as a planning band.
