Mickey Thompson Tires - Dodge CHALLENGER DEMON 170 2023 Owner's Manual Supplement

NOTE:
•
The threshold for ethanol detection is 5%.
•
Ethanol percentages are distinguished by color.
○
White — Ethanol Detected: Ethanol content is
between 5% and 64%. The power display will
indicate between 900 HP and 1024 HP accord-
ing to the detected ethanol content.
○
Blue — High Ethanol Detected: Ethanol content is
65% or higher. Full power is available up to
1025 HP under nominal conditions.
•
The target air to fuel ratio is a function of detected
ethanol content and driving conditions.
•
Commercially available E85 fuels are typically not
exactly 85% ethanol. Ethanol content is adjusted
seasonally to ensure proper engine performance.
The engine may be difficult to start if the fuel's etha-
nol content is too high for ambient temperature.
•
To maintain the necessary air to fuel ratio, addi-
tional fuel flow is required as ethanol content
increases. "Race" fuels with ethanol content above
85% will not increase engine power and are not rec-
ommended, as the necessary fuel flow may be more
than the injectors can provide. If this condition is
detected, engine performance will be reduced.
•
If the vehicle will not be driven for more than a
month, it is recommended to run the engine with
premium gasoline before storage

MICKEY THOMPSON TIRES

Recommended Tire Pressure:
Street: 32 psi (220.6 kPa) cold for all tires
Drag Strip:
ET Street R Rear Tires – depending on the outside
•
temperature and track conditions, the operating
pressure recommendation is 18-24 psi (124–
165 kPa) hot.
• ET Street Front Runner Tires – Increase front tire
pressure to reduce rolling resistance. Do not exceed
maximum tire inflation rating.
•
Tires may exceed the speed rating of 149 mph
(240 km/h) only in drag race applications and never
in highway use.

Mickey Thompson Drag Radials
NOTE:
•
Due to the design construction of the ET Street R
rear tires, some tire imbalance is to be expected
and is considered normal.
FEATURES OVERVIEW
•
Always return the tire pressure to street recom-
mended pressure levels before driving vehicle on
public roads.
•
To help mitigate tire-to-rim slip on prepped surfaces,
Dodge recommends the use of high-tack gasket
sealant on the rim bead.
•

for additional tire information.
WARNING!
Serious injury or death may result from tire failure
due to under-inflation and/or overloading. Always
adjust your tires to the proper inflation pressure (See
tire information placard). Always inspect your tires for
any signs of damage before proceeding onto public
roads or race tracks.
WARNING!
Mickey Thompson Rear Drag Radials and Front Run-
ners meet U.S. D.O.T. requirements, but they are not
intended for extended street and highway use as the
expected miles of wear from the racing compound is
greatly reduced compared to a conventional road tire.
CAUTION!
Mickey Thompson Rear Drag Radials and Front Run-
ner tires are not recommended for driving in wet
weather conditions. Drive cautiously and reduce
speeds in these conditions.
