The size on the placard inside the driver's door jamb is the one your car left the factory with. Match that, not this table, if they differ; a previous owner may have changed wheels.

Worth knowing about the 2021 Challenger

  • Connector. Both front blades use a j-hook connector. A blade of the right length with the wrong connector will not clip on, so check the connector before you buy.
  • LED lighting. The front turn signal, rear turn signal, brake light, tail light, reverse light, license plate are sealed LED units with no user-replaceable bulb. A failure means replacing the assembly.
  • Bulbs. The manual lists H11LL fog bulbs, and models with HID headlamps use D3S bulbs that a dealer services.
  • Tire chains. The manual permits chains or cables, on the drive wheels only, fitted to the standard tire size. Chains for this size on Amazon →
  • Tires. The manual allows rear-only devices on the RWD 235/55R18 (Peerless Super Z6 type) and the AWD 235/55R19 (S Class type), and none on the R/T Scat Pack.
  • Wheels. The manual gives 130 ft-lbf for standard models and 111 ft-lbf for SRT models.
  • Fuel. The 5.7-liter V8 recommends 89 octane with the automatic and needs 91 or higher with the manual transmission.
