Iso Rivolta Fidia front tyre pressure

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 front

2.31 bar · 231 kPa at the steering axle

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

The front axle of a Iso Rivolta Fidia steers and, on front-wheel drive cars, often pulls as well. Catalogue front pressure is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include 245/40R18, 205/60R16 and 195/65R15 — interpolated from the catalogue midpoint, not a second factory sticker.

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 (245/40R18 and others)

Planning cold pressures for sizes often seen on a passenger car. This Fidia sample opens with 245/40R18, then 205/60R16 and 195/65R15.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
245/40R18	36	—	2.48	—	248	—	Wide touring 18-inch
205/60R16	34	—	2.34	—	234	—	Taller 16-inch
195/65R15	34	—	2.34	—	234	—	Very common compact
215/50R17	35	—	2.41	—	241	—	Plus-size 17-inch
215/55R16	34	—	2.34	—	234	—	Slightly wider 16-inch
225/45R17	35	—	2.41	—	241	—	Sport 17-inch
185/65R15	33	—	2.28	—	228	—	Small / older car
205/55R16	34	—	2.34	—	234	—	Typical mid-compact OEM

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	37 psi / 2.55 bar

Steering feel on the Fidia lives on this axle. Do not drop front pressure to “soften” a plus-size 195/65R15; you will roll the sidewall in a roundabout.

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.

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.

When does TPMS warn on a Iso Rivolta Fidia?

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 Iso Rivolta Fidia?

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

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 PSI if I plus-size toward 195/65R15?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/40R18, 205/60R16 and 195/65R15 as a planning band.
