IMPORTANCE OF TIRE PRESSURE
The main factor that affects tire performance is tire pressure.
Excessive Tire Pressure:
Excess pressure weakens the tire by
not allowing the tire to absorb impacts,
producing tire failure as well as irregular
wear and reduce puncture resistance.
It reduces the rolling surface, causing
excessive wear in the tires due to the loss
of traction.
Low Tire Pressure:
Under inflation produces an increase of
the casing flex. Casing flex generates
excessive heat causing casing fatigue,
excessive tread shoulder wear, cap
separation and ultimately tire failure.
Important: According to the specifications established by the tire manu-
facturers, the tire pressure should be regulated when tires are COLD
(allow the tires to cool for 3-4 hours after use). You may have a fluctua-
tion of an additional 18 % of pressure due to the temperature increase
caused by tire operation than the original calibrated pressure. VIGIA will
indicate this pressure increase in its operation. Its functioning is correct.
DO NOT BLEED the tires.
