Different Tire Pressures for the Front and Rear Tires: For some
vehicles, the recommended front and rear inflation pressures may
be different (such as in the example shown in Figure 2). Make sure
you take this into account during inflation pressure checks and when
rotating tires.
Pressure Loss: Tires can lose 1 psi (7 kPa) per month under normal
conditions and can lose 1 psi (7 kPa) for every 10˚F (5.6˚C temperature
drop. A puncture, leaking valve, or other damage could also cause
inflation pressure loss. If a tire loses more than 2 psi (14 kPa) per
month, have it checked by a qualified tire service professional.
Tips For Safe Tire Inflation
SAFETY WARNING
Inflating an unsecured tire is dangerous. If it bursts, it could be hurled
into the air with explosive force resulting in serious personal injury or
death. Never inflate a tire unless it is
secured to the vehicle or a tire
mounting machine.
• Check your tire pressures, including your spare tire, monthly
and before long trips or carrying extra weight. Be sure to use an
accurate pressure gauge.
•
Check inflation pressure when the tires are “cold.” Tires are
considered “cold” when the vehicle has been parked for three
hours or more, or if the vehicle has been driven less than a mile at
moderate speed.
•
Never release pressure from a hot tire in order to reach the
recommended cold tire pressure. Normal driving causes tires
to run hotter and inflation pressure to increase. If you reduce
inflation pressure when your tires are hot, you may dangerously
underinflate your tires.
•
If it is necessary to adjust inflation pressure when your tires are
“hot,” set their pressure to 4 psi (28 kPa) above the recommended
cold inflation pressure. Recheck the inflation pressure when the
tires are cold.
•
If your tires lose more than 2 psi (14 kPa) per month, the tire, the
valve, or wheel may be damaged. Consult a qualified tire service
professional for an inspection.

Tire Pressure Monitoring System (TPMS)
A tire pressure monitoring system (TPMS) is a safety system found
in most vehicles manufactured after 2005. There are pressure
sensing transmitters mounted inside of each tire that sends readings
to the central computer (ECU) in your vehicle. The TPMS system will
alert you when one or more of your tires are underinflated by 25%
or more by turning on a warning light on your vehicle’s dashboard or
heads up display (HUD) screen. This means that one or more of your
tires may have a low-pressure condition. Follow the instructions in your
owner’s manual.
Rotation and Wear
Falken recommends rotating your tires at least every 8,000km (5,000
miles) and periodically inspecting your tires to make sure they are
free of road hazards (such as nails, screws, large wood splinters, etc.)
that might penetrate your tires causing them to lose air pressure and
to ensure they are wearing evenly. Common irregular wear patterns
are: misalignment wear, where the tire shows excessive outer or inner
tread wear. Tire sidewalls should also be inspected for cuts, snags,
bruises, and weather cracking. If any of these noted conditions are
present during inspection, we recommend returning to your servicing
tire dealer to be corrected to ensure long tire life. ***Never include a
temporary spare tire in your rotation pattern***
