Ruf Turbo Florio tyre pressure in bar

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 Ruf Turbo Florio catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

Ruf Turbo Florio placard versus sidewall

The tyre-information placard on a Ruf Turbo Florio 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 (215/55R16 and others)

If your Ruf Turbo Florio no longer wears the OEM diameter, start at the row nearest 215/55R16 or 185/65R15 and confirm with the tyre maker’s load table.

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

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	36 psi / 2.48 bar

How to set the Turbo Florio

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

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

Ruf notes

No special Ruf exception: the Turbo Florio 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 Ruf Turbo Florio 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 Ruf sticker and this page disagree, the sticker wins.

Questions about this Turbo Florio

What is that in bar and kPa for the Turbo Florio?

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

When does TPMS warn on a Ruf Turbo Florio?

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 Ruf Turbo Florio?

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

What PSI if I plus-size toward 205/55R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/55R16, 185/65R15 and 205/55R16 as a planning band.

What tyre pressure should a Ruf Turbo Florio 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.
