2018 Dodge Challenger
- What is the recommended tire pressure for a 2018 Dodge Challenger?
- The 2018 Dodge Challenger uses 33 PSI cold on the front axle and 33 PSI cold on the rear axle. These are the OEM specifications. Always measure tire pressure when the tires are cold — before driving or after sitting for at least 3 hours.
- What tire size does the 2018 Dodge Challenger use?
- The standard (base trim) tire size for the 2018 Dodge Challenger is 215/65R17. Higher trim levels and optional packages may use a different size — check the sticker inside your driver's door for the exact specification for your vehicle.
- How do I convert the 2018 Dodge Challenger tire pressure to bar?
- 33 PSI = 2.3 bar (front) and 33 PSI = 2.3 bar (rear). In kPa: 228 kPa front and 228 kPa rear. Multiply PSI × 0.0689 to convert to bar.
- Why are the front and rear tire pressures the same on the 2018 Dodge Challenger?
- The 2018 Dodge Challenger uses equal pressure front and rear (33 PSI). The vehicle's weight distribution and symmetric tire sizing mean both axles carry similar loads per tire.
- What happens if the 2018 Dodge Challenger tires are underinflated?
- Running 5+ PSI low on the Dodge Challenger causes uneven shoulder wear, increased rolling resistance (worse fuel economy), higher tire operating temperature, and reduced wet braking performance. In extreme cases, chronic underinflation can cause sidewall failure. Check pressure monthly and always after a large temperature swing.
- What do the numbers in 215/65R17 mean on the 2018 Dodge Challenger?
- On the 2018 Dodge Challenger, 215/65R17 breaks down as: 215 = section width in millimetres (8.46"), 65 = aspect ratio (the sidewall is 65% of the width, so 139.8 mm / 5.5" tall), R = radial construction, and 17 = the wheel diameter in inches.
- What is the overall diameter of the 2018 Dodge Challenger tires?
- The 215/65R17 tire on the 2018 Dodge Challenger has an overall diameter of about 28" (711 mm) and a rolling circumference of roughly 87.98", giving about 720 revolutions per mile. Fitting a tire with a different diameter will throw off your speedometer and odometer.
