What size tires are on a Dodge Viper?
The Dodge Viper does not use a single tire size. Size varies by generation and trim, with different wheel diameters and staggered front/rear setups across the model’s history.
Below is a generation-by-generation guide to the most commonly equipped stock sizes, along with notes on how to verify the exact fit for your particular car. For any Viper, the definitive sizes are listed on the door jamb placard or in the owner's manual, and you should always confirm before purchasing replacements.
Tire sizes by generation
Gen I/II (1992–2002)
Early Vipers used a staggered setup with a wide rear tire and a smaller wheel at the front. Exact sizes can vary by year and model variant, but the following are representative stock values commonly cited for these generations.
- Front: 275/40ZR17
- Rear: 345/35ZR17
These sizes reflect the era’s 17-inch wheels and the Viper’s characteristic emphasis on rear grip. Always verify for your specific year and trim, as there were several production tweaks over this period.
Gen III (2003–2006)
With the introduction of the third generation, Vipers generally shifted to larger wheels and a more modern tire profile while maintaining a staggered setup.
- Front: 275/40ZR18
- Rear: 345/30ZR19
This configuration supported improved grip and stability on the then-new chassis and bodywork. As with earlier models, exact sizes can vary by sub-models and optional equipment.
Gen IV (2008–2010)
In the Gen IV era, Dodge refined the tire package further to suit the higher-performance focus of the Viper, including earlier SRT variants and the performance-oriented ACR.
- Front: 265/40ZR18
- Rear: 325/40ZR19
These sizes reflect a slightly narrower front and a correspondingly wide rear, paired with 18-inch front and 19-inch rear wheels that characterized the Gen IV lineup.
Gen V / SRT Viper (2013–2017)
The final generation, including the SRT Viper and its track-ready variants, settled on a distinctive 18-inch front and 19-inch rear setup with notably wide rear tires for grip and stability at speed.
- Front: 275/35ZR18
- Rear: 345/30ZR19
These sizes were standard on many Gen V cars, including the performance-focused trims, although some configurations or regional releases might show slight variations. Always confirm against the vehicle's placard for your exact build.
How to verify the exact size on your Viper
To ensure you’re buying the correct tires, check the vehicle’s official documentation and markings. The door jamb placard (usually on the driver’s side) lists the exact tire size recommended by the manufacturer. If the placard is missing or unreadable, consult the owner's manual or contact a Dodge/Muscle car specialist with your VIN to confirm the precise sizes for your specific car and year.
Common questions
Are there alternate tire sizes for special editions?
Yes. Some limited or track-focused editions (like the ACR variants) may use different profiles or width configurations, and regional market versions can also vary. Always verify with official documentation or a trusted dealer when dealing with a special edition or non-U.S. car.
Summary
In short, there isn’t a single tire size for the Dodge Viper. The stock sizes have evolved with each generation, typically featuring an 18-inch front wheel and a 19-inch rear wheel in the later models, with front widths around 275 mm and rear widths around 325–345 mm, depending on the year. For any Viper, the most reliable way to know the correct tire size is to check the door placard or the owner’s manual for your specific vehicle and year.
Final takeaway: when replacing tires on a Dodge Viper, always verify the exact specifications for your year and trim to maintain performance and safety standards.
