Tire Pressures For High Speed Operation; Radial Ply Tires; Tire Repair - Fiat 124 SPIDER 2017 Owner's Manual

Inflation pressures specified on the
placard are always "cold tire inflation
pressure". Cold tire inflation pressure is
defined as the tire pressure after the
vehicle has not been driven for at least
three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of
three hours. The cold tire inflation
pressure must not exceed the
maximum inflation pressure molded into
the tire sidewall.
Check tire pressures more often if
subject to a wide range of outdoor
temperatures, as tire pressures vary
with temperature changes.
Tire pressures change by approximately
1 psi (7 kPa) per 12°F (7°C) of air
temperature change. Keep this in mind
when checking tire pressure inside a
garage, especially in the Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 psi
(21 kPa), which equals 1 psi (7 kPa) for
every 12°F (7°C) for this outside
temperature condition.
Tire pressure may increase from 2 to
6 psi (13 to 40 kPa) during operation.
DO NOT reduce this normal pressure
build up or your tire pressure will be too
low.
Tire Pressures For High Speed
Operation
The manufacturer advocates driving at
safe speeds and within posted speed
limits. Where speed limits or conditions
are such that the vehicle can be driven
at high speeds, maintaining correct tire
inflation pressure is very important.
Increased tire pressure and reduced
vehicle loading may be required for
high-speed vehicle operation. Refer to
your authorized tire dealer or original
equipment vehicle dealer for
recommended safe operating speeds,
loading and cold tire inflation pressures.
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to
fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).

Radial Ply Tires

Warning!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability
could cause a collision. Always use radial
ply tires in sets of four. Never combine
them with other types of tires.

Tire Repair

If your tire becomes damaged, it may
be repaired if it meets the following
criteria:
The tire has not been driven on when
flat.
The damage is only on the tread
section of your tire (sidewall damage is
not repairable).
The puncture is no greater than a ¼
of an inch (6 mm).
Consult an authorized tire dealer for tire
repairs and additional information.
Damaged Run Flat tires, or Run Flat
tires that have experienced a loss of
pressure should be replaced
immediately with another Run Flat tire
of identical size and service description
(Load Index and Speed Symbol).
