315/35R17 Tire Size

All You Need to Know About 315/35R17 Tires

315/35R17 tires are 315 mm wide, with a 35% aspect ratio and a 17-inch wheel diameter, resulting in an overall diameter of approximately 25.7 inches and a sidewall height of about 4.34 inches.

This page analyzes 315/35R17 as a size-defined tire, where physical dimensions determine fitment, clearance, and wheel compatibility. For load-standard behavior and pressure-dependent capacity, see P315/35R17 tires.

The 315/35R17 size combines extreme section width (315 mm) with a moderate sidewall height, shifting fitment constraints toward width-driven clearance rather than diameter limitations.

315/35R17 Size Quick Specs

• Overall diameter: ≈25.7"
• Section width: 315 mm 
• Sidewall height: ≈110 mm
• Common Applications: 17x11" or 17x12" wheels
• Approved rim width range: 10.5-12.5"
• Optimal rim width ≈11.0"
• Wheel diameter: 17"
• Revolutions per mile: ≈786

Note: The calculated overall diameter of 315/35R17 is ≈25.7 inches. Real-world measurements for 315/35R17 may vary by approximately +/- 0.1–0.3 inches depending on tread design and manufacturer construction.

315/35R17 Common Vehicle Fitment

315/35R17 has limited OEM adoption in the U.S. market. Its most notable factory application is the rear axle of the Chevrolet Corvette C4 ZR-1 (1990–1995), which was equipped from the factory with this size. Beyond that application, 315/35R17 does not appear as a standard OEM size and is used primarily in non-standard or custom fitment contexts.</p

• Chevrolet Corvette (C4 ZR-1, 1990–1995) - confirmed OEM rear fitment
• Chevrolet Corvette (C5) - not an OEM tire size; requires ≥10.5–11" wheel width and clearance verification if used as a non-standard replacement
• Dodge Viper (RT/10, GTS) - OEM rear size is 335/35R17; 315/35R17 is not a factory-specified size and represents a narrower alternative requiring fitment evaluation

In 315/35R17 applications, fitment depends on maintaining compatibility with the approved rim width range and verifying clearance to suspension components and fender edges due to the 315 mm section width.

315/35R17 Dimensions in Inches

The 315/35R17 tire size is approximately 12.40 inches wide, 25.7 inches tall overall, and has a 4.34-inch sidewall.

The circumference of 315/35R17 is approximately 80.7 inches, which results in about 786 revolutions per mile.

Because the overall diameter of 315/35R17 remains close to common 26-inch performance sizes, speedometer variation is minimal when compared with nearby sizes within the ±3% range.

315/35R17 in Inches: All Measurements

• Total height:≈25.7"
• Section width:≈12.40"
• Sidewall height: ≈4.34"
• Wheel diameter:17"
• Circumference: ≈80.7"

Comparison of 315/35R17 With Similar Tire Sizes

Within ultra-wide 17-inch performance sizing, 315/35R17 is commonly compared with 305/35R17 as a narrower alternative and 315/40R17 as a taller option.

Difference Between 315/35R17 and 305/35R17

• Width: 315/35R17 is 10 mm wider
• Overall diameter: 315/35R17 is ≈0.28 inches (≈1.1%) larger

At ≈1.1%, the difference between 315/35R17 and 305/35R17 remains within the accepted ±3% diameter range, making these sizes interchangeable from a diameter standpoint. The change is width-driven. Moving from 305/35R17 to 315/35R17 increases section width, which requires wider wheels and reduces available clearance to suspension and fender components.

Difference Between 315/35R17 and 315/40R17

• Section width: Identical (315 mm)
• Overall diameter: 315/40R17 is ≈1.24 inches (≈4.8%) larger than 315/35R17

At ≈4.8%, the difference between 315/40R17 and 315/35R17 exceeds the ±3% threshold, making these sizes not directly interchangeable. The larger diameter of 315/40R17 increases ride height by approximately 0.62 inches and results in speedometer under-reading of about 2.9 mph at 60 mph. The taller sidewall also increases deformation under load compared to 315/35R17.
