All You Need To Know About P205/55R17 Tire Size
The P205/55R17 tire size has a section width of 205 millimeters, an aspect ratio of 55%, and a 17-inch wheel diameter, producing a calculated overall diameter of approximately 25.88 inches (25.9'') and a calculated sidewall height of approximately 4.44 inches (112.75 mm).
The "P" prefix in P205/55R17 identifies a P-metric passenger-vehicle service description, a separate designation system from Euro-metric or LT-metric sizes that can share the same numeric width, aspect ratio, and wheel diameter. Because P205/55R17 combines a 205 mm section width with a 55% aspect ratio, its sidewall works out taller relative to its width than a lower-aspect-ratio tire of the same section width, a relationship that follows directly from the aspect-ratio calculation used to size P205/55R17.

P205/55R17 Dimensions in Inches
The P205/55R17 tire size is approximately 8.07 inches wide, 25.88 inches tall overall, with a sidewall approximately 4.44 inches high.
This 4.44-inch sidewall is the direct result of applying the 55% aspect ratio to the 8.07-inch section width of P205/55R17. Because that sidewall is taller than it would be at a lower aspect ratio on the same width, P205/55R17 has more sidewall material available to flex between the road and the wheel than a lower-profile size built on the same 17-inch wheel diameter. In wheel-well terms, the 25.88-inch overall diameter of P205/55R17 is the figure that determines static clearance and rollout distance per revolution.
P205/55R17 in Inches: All Measurements
- Width: 8.07 in (205 mm)
- Sidewall Height: 4.44 in (112.75 mm)
- Wheel Diameter: 17 in
- Overall Diameter: 25.88 in, approximately 25.9 in (657.3 mm)
- Circumference: 81.29 in, approximately 81.3 in (2065 mm)
Comparison of P205/55R17 With Alternative Tire Sizes
P205/55R17 is documented for comparison against 205/50R17, which shares the same 205 mm section width at a lower aspect ratio, and against 215/55R17, which shares the same 55% aspect ratio at a wider section width. Calculated against P205/55R17's 25.88-inch overall diameter, 205/50R17 comes out noticeably shorter while 215/55R17 comes out only slightly taller.
Difference Between P205/55R17 and 205/50R17 Tire Sizes
205/50R17 is a dimensional alternative to P205/55R17, with an overall diameter approximately 3.1% smaller than P205/55R17, a difference that falls outside the ±3% guideline.
- Width Difference: 205/50R17 and P205/55R17 share the same 205 mm section width, so there is no width difference between them.
- Diameter Difference: 205/50R17 is approximately 0.81 inches (3.1%) shorter in overall diameter than P205/55R17.
- Interchangeability: The 3.1% overall-diameter difference between P205/55R17 and 205/50R17 exceeds the ±3% diameter guideline, so 205/50R17 is not a direct replacement for P205/55R17 under that guideline.
- Practical Difference: Relative to P205/55R17, 205/50R17 has a shorter sidewall and a smaller overall diameter, corresponding to reduced ride height and less rollout distance per revolution.

Difference Between P205/55R17 and 215/55R17 Tire Sizes
215/55R17 is a dimensional alternative to P205/55R17, with an overall diameter approximately 1.7% larger than P205/55R17, a difference that falls within the ±3% guideline.
- Width Difference: 215/55R17 is 10 mm wider than P205/55R17 (215 mm vs. 205 mm).
- Diameter Difference: 215/55R17 is approximately 0.43 inches (1.7%) taller in overall diameter than P205/55R17.
- Interchangeability: The 1.7% overall-diameter difference between P205/55R17 and 215/55R17 passes the ±3% diameter guideline, meaning it is dimensionally eligible for consideration under that guideline, not automatically interchangeable. Wheel-width compatibility, load capacity, clearance, and vehicle-specific requirements still need to be verified with a tire professional. See our guide on how the ±3% rule works for more on this screening step.
- Practical Difference: Relative to P205/55R17, 215/55R17 has a wider section width and a slightly larger overall diameter, corresponding to a larger physical footprint and marginally reduced wheel-well clearance.
