What size tires are on a Chevy SS?
The factory tire setup for the Chevy SS is 245/40ZR19 in the front and 275/35ZR19 in the rear, mounted on 19-inch wheels.
The high-performance sedan, produced from 2014 to 2017 for the U.S. market, used bold, track-inspired tires to match its 6.2-liter V8. This article outlines the official tire sizes, wheel fitment, and practical notes for replacement or upgrades.
Stock tire specification
Here are the official factory sizes as supplied for U.S.-spec Chevy SS models, along with the wheel widths they were paired with.
- Front: 245/40ZR19 on 19x8.5-inch wheels
- Rear: 275/35ZR19 on 19x9.5-inch wheels
That combination gives balanced grip and handling, with a wider rear tire for traction and a stiffer front end for steering feedback.
Year range and fitment notes
The above sizes apply to the Chevy SS models sold in the United States during the 2014–2017 production window. Chevrolet did not widely vary tire sizes across these model years; aftermarket discussions similarly reference the same stock dimensions for compatibility.
- Model years: 2014–2017 in the U.S.
- Front/rear sizes remained consistent across these years.
For most buyers, this means standard replacements and common aftermarket options are readily available in these exact sizes.
Upgrading and replacement considerations
If you're replacing tires or considering upgrades, keep these guidelines in mind to preserve performance and safety:
- Use the stock sizes (245/40R19 front and 275/35R19 rear) when possible to maintain intended handling and speedometer accuracy.
- Keep the overall tire diameter within a few percent of stock and aim to preserve the front/rear size ratio to maintain balance between grip and stability.
- When changing wheel widths or going with different tire models, consult a tire professional to verify fitment on the 19-inch wheels (front 8.5-inch width, rear 9.5-inch width) and to ensure adequate clearance and load rating.
Owners often choose to upgrade to high-performance summer tires or all-season variants within the same sizes, but professional guidance helps avoid rubbing, incorrect ABS response, or speedometer errors.
Summary
The Chevy SS leaves the factory shod with 245/40R19 front and 275/35R19 rear tires on 19-inch wheels, a setup designed to balance sport handling with daily usability. Replacement options and aftermarket choices exist within these same dimensions, with professional advice recommended for any wheel or tire upgrades.
