What size tires are on a Hellcat?
The typical factory tire setup on Dodge Challenger SRT Hellcat and Charger SRT Hellcat models uses 20-inch wheels with 275/40R20 front tires and 315/35R20 rear tires. This arrangement is common across many years and configurations, though exact sizing can vary by edition and wheel package.
The tire sizes you’ll see on a Hellcat can depend on the specific model year, whether the car has a Widebody package, and which wheel options were chosen from the factory. Always verify the exact figures for your car on the door placard or in the owner's manual, especially if you’re shopping for tires or wheels as replacements.
Stock tire sizes and wheel packages
The factory spec for most Hellcat configurations is summarized below. Note that exact numbers can vary by year and trim, so use these as a baseline and confirm on your vehicle.
- Front tires: 275/40R20
- Rear tires: 315/35R20
- Front wheel width: 20x9 inches
- Rear wheel width: 20x11 inches
These sizes are representative of the common 20-inch wheel setups found on several Hellcat variants, including several Challenger and Charger models with standard wheels. If your car is a Widebody or has a special edition, there can be minor variations, so always check your vehicle’s labeling for the precise numbers.
Notes on variations and verification
Variations exist across model years and packages. Widebody editions typically maintain the same front tire sizing while sometimes using a wider rear wheel or a different tire profile depending on the model year and market. To ensure you’re matching the exact spec for your car, verify with:
- The driver-side door jamb placard
- The owner's manual or official Dodge build sheet
- The tire sidewall, which shows the exact size currently installed
If you plan to replace tires or wheels, confirming these details helps ensure proper clearance, handling characteristics, and load ratings.
Bottom line: Most Hellcats run 275/40R20 fronts and 315/35R20 rears on 20-inch wheels (20x9 front, 20x11 rear). Always confirm the exact size for your specific model and year, as packages like Widebody or special editions can influence the numbers.
Summary: The standard factory tire setup for Hellcat models is a 275/40R20 front and 315/35R20 rear on 20-inch wheels, with verification required for Widebody and special editions. This configuration supports the high-performance intent of the Hellcat while allowing for aftermarket changes if needed, provided the replacements meet load and speed ratings.
