Ferrari 458 Italia Owner's Manual page 76

Occasionally, the system may not detect which wheel signals
a failure. If this is the case, then only the message "Check tyre
pressure" will be displayed as shown in example 6.
Tyre puncture
Regardless of the type of screen page on the left TFT display, when
the instrument panel receives the signal from the tyre pressure
ECU that the pressure level of one or more tyres is below the
alarm threshold, the screen page shown in example
not to proceed for vehicles fitted with normal tyres) or example
(warning to proceed at a maximum speed of 80 km/h (50 mph)
for vehicles fitted with Run Flat tyres) appears immediately. At the
same time, a warning light comes on on the panel (see page 117) in
fixed mode.

The screen page is displayed for 20 seconds and then the screen
page that was previously displayed reappears whereas the warning
light remains on in fixed mode.
If normal tyres are used, the failure follows the same display logic
as the other priority level 0 faults (see the "Fault displaying logic"
paragraph on page 111) until the situation is corrected and the
system is recalibrated.
If the vehicle is fitted with Run Flat tyres, the maximum distance
allowed in a "tyre puncture" state is 100 km (62 mi). The
instrument panel will calculate the residual tyre life and will
redisplay the screen page shown in example
The same screen page (warning not to exceed a maximum speed
of 80 km/h) is displayed if the vehicle exceeds 80 km/h (50 mph).
Once the distance of 100 km (62 mi) has been exceeded, the panel
displays the screen page shown in example

If you call up the TYRES screen page, you can identify the
