2006 DODGE RAM SRT-10 check engine

Over inflation will cause rapid center wear (1) reduc-
tion in the tire’s ability to cushion shocks.
Improper inflation can cause:
Uneven wear patterns
Reduced tread life
Reduced fuel economy
Unsatisfactory ride
Vehicle drift
For proper tire pressure specification refer to the vehicles Owners Manual.
DIAGNOSIS AND TESTING
PRESSURE GAUGES
A quality air pressure gauge is recommended to check tire pressure. After checking the air pressure, replace valve
cap finger tight.
TIRE NOISE OR VIBRATION
Radial-ply tires are sensitive to force impulses caused by improper mounting, vibration, wheel defects, or possibly
tire imbalance.
To find out if tires are causing the noise or vibration, drive the vehicle over a smooth road at varying speeds. Note
the noise level during acceleration and deceleration. The engine, differential and exhaust noises will change as
speed varies, while the tire noise will usually remain constant.
TREAD WEAR INDICATORS
Tread wear indicators (3) are molded into the bottom
of the tread grooves. When tread depth is 1.6 mm
(1/16 in.), the tread wear indicators (3) will appear as
a 13 mm (1/2 in.) band.
Tire replacement is necessary when indicators appear
in two or more grooves or if localized balding occurs.
