Snow Tires; Tire Spinning; Tread Wear Indicators - Dodge Challenger SRT 392 2015 Operating Information Manual

Snow Tires

Some areas of the country require the use of
snow tires during the winter. Snow tires can be
identified by a "mountain/snowflake" symbol on
the tire sidewall.
If you need snow tires,
select tires equivalent in
size and type to the origi-
nal equipment tires. Use
snow tires only in sets of
four; failure to do so may
adversely
safety and handling of
your vehicle.
Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at sustained
speeds over 75 mph (120 km/h). For speeds
above 75 mph (120 km/h) refer to original
equipment or an authorized tire dealer for rec-
ommended safe operating speeds, loading and
cold tire inflation pressures.
While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of non-
218
studded tires. Some states prohibit studded
tires; therefore, local laws should be checked
before using these tire types.

Tire Spinning

When stuck in mud, sand, snow, or ice condi-
tions, do not spin your vehicle's wheels above
30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping.
Refer to "Freeing A Stuck Vehicle" in "What To
Do In Emergencies" for further information.

WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle's wheels faster than
30 mph (48 km/h) for more than 30 seconds
continuously when you are stuck, and do not
let anyone near a spinning wheel, no matter
what the speed.

Tread Wear Indicators

Tread wear indicators are in the original equip-
ment tires to help you in determining when your
tires should be replaced.
1 — Worn Tire
2 — New Tire
These indicators are molded into the bottom of
the tread grooves. They will appear as bands
when the tread depth becomes a 1/16 of an inch
(2 mm). When the tread is worn to the tread
wear indicators, the tire should be replaced.
Refer to "Replacement Tires" in this section for
further information.
