All You Need to Know About 245/50R17 Tires
245/50R17 tires are 245 mm wide, with a 50% aspect ratio and a 17-inch wheel diameter, resulting in an overall diameter of 26.6 inches and a sidewall height of 4.8 inches.
This page focuses on the 245/50R17 size and its dimensional and ride-related characteristics. For passenger load standard specifications and pressure-related behavior, see P245/50R17 tires.
The 245/50R17 size is positioned in the touring and comfort-oriented segment, where a relatively wide tread is paired with a taller sidewall to improve ride quality, straight-line stability, and road isolation.
Compared with a lower-profile size such as 245/45R17, the 245/50R17 increases both sidewall height and rolling diameter. That additional height allows the tire to absorb more surface irregularities while slightly raising the vehicle and changing effective gearing.
In some listings, this size may appear as P245/50R17, indicating a passenger load standard. While the physical dimensions remain unchanged, load behavior depends on inflation pressure and rating rather than on size alone.
245/50R17 Size Quick Specs
- Approved rim width range: 7.0–8.5"
- Width: 245 mm
- Sidewall height: 122.50 mm
- Overall diameter: ≈26.6"
- Wheel diameter: 17 in
Note: The calculated overall diameter of 245/50R17 is ≈26.6 inches. Slight variation may occur across manufacturers because tread depth and casing design can shift the mounted diameter slightly.
245/50R17 Common Vehicle Fitment
245/50R17 is used on midsize and full-size sedans where ride comfort and highway stability are prioritized without moving into very tall sidewall configurations. In the U.S. market, it appears both as an OE-size reference and as a replacement size in comfort-oriented setups.

Because 245/50R17 increases overall diameter compared with lower-profile 17-inch sizes, fitment should still be verified based on wheel width, offset, and available clearance before installation.
245/50R17 Dimensions in Inches
The 245/50R17 tire size measures approximately 9.7 inches in width, 26.6 inches in overall diameter, and has a sidewall height of about 4.8 inches.
The taller sidewall increases vertical flexibility, allowing the tire to absorb more impact from road imperfections. This contributes to smoother ride quality and stable highway behavior, though it also introduces slightly more sidewall movement than a lower-profile alternative such as 245/45R17.
245/50R17 in Inches: All Measurements
- Overall diameter: ≈26.6"
- Width: ≈9.7"
- Sidewall height: ≈4.8"
- Wheel diameter: 17"
- Circumference: ≈83.7"

Comparison of 245/50R17 With Similar Tire Sizes
Within the 17-inch range, 245/50R17 aligns with taller mid-width configurations. The closest references are 245/45R17 as the lower-profile alternative and 255/50R17 as a wider option with a similar height class.
Difference Between 245/50R17 and 245/45R17 Tire Sizes
The 245/45R17 is shorter while maintaining the same width:
- Width: identical at 245 mm
- Overall diameter: 245/45R17 is ≈0.98 inches (≈3.7%) smaller than 245/50R17
Because this reduction exceeds the ±3% threshold, 245/50R17 and 245/45R17 are not directly interchangeable. The smaller diameter lowers ride height and increases revolutions per mile, which affects speedometer accuracy, gearing, and ground clearance.
Difference Between 245/50R17 and 255/50R17 Tire Sizes
The 255/50R17 is wider and slightly taller:
- Width: 255/50R17 is 10 mm wider than 245/50R17
- Overall diameter: 255/50R17 is ≈0.39 inches (≈1.5%) larger than 245/50R17
Since the difference remains within the ±3% range, 245/50R17 and 255/50R17 are generally interchangeable from a rolling-diameter standpoint. The added width affects fitment space, so inner clearance, outer fender space, and approved rim width should all be verified before installation.
