Overall Diameter

The diameter of a tire is a crucial aspect, influencing ground clearance, speedometer readings, and ride comfort. The 225/55r17 sports a slightly larger diameter (26.74 inches) compared to the 215/55r17 (26.31 inches), a difference of 0.43 inches.

This increased diameter provides the 225/55r17 with more ground clearance, which is advantageous for off-road driving or navigating rough terrains. However, the larger diameter will result in a marginally lower speedometer reading than the 215/55r17. It’s also worth noting that the increased diameter can contribute to a smoother ride as it covers more ground per revolution.

Tire Width
The 225/55r17 features a broader section width (8.86 inches) than the 215/55r17 (8.46 inches), a 4.7% difference. The wider width increases the tire’s contact patch with the road, enhancing traction during acceleration, braking, and cornering.

However, this comes at the cost of potentially producing more road noise due to the larger contact area. Conversely, the 215/55r17’s narrower width might offer slightly less grip, especially in wet or slippery conditions.

The circumference of the 225/55r17 (84.02 inches) is marginally larger than that of the 215/55r17 (82.66 inches). A larger circumference corresponds to lower speedometer readings, as each tire rotation covers more ground.

The increased circumference also means a smoother ride, as the tire makes fewer revolutions per mile.

Revolutions Per Mile

Revolutions per mile

With fewer revolutions per mile (754.11), the 225/55r17 covers more distance per revolution, potentially reducing wear and tear and extending the tire’s lifespan.

On the contrary, the 215/55r17 registers more revolutions per mile (766.53), which might lead to increased friction with the road surface and, thus, potentially reduced longevity.

Sidewall Height
The 225/55r17 has a taller sidewall height (4.87 inches) compared to the 215/55r17 (4.66 inches). This increased height provides more cushioning against road irregularities, leading to a smoother ride and better traction on snowy or icy roads. On the other hand, the 215/55r17’s smaller sidewall height may translate into a harsher ride but could offer a sportier look.

Rim Size
Both tires are designed to fit 17-inch rims. However, their recommended rim width ranges differ, with the 215/55r17 being suitable for 6.0-7.5 inches and the 225/55r17 designed for a broader 7.0-8.5 inches.

A wider rim associated with the 225/55r17 can contribute to a more aggressive and sporty look, while the narrower rim compatibility of the 215/55r17 might provide a more classic appearance.

How much taller is a 225/55r17 tire than a 215/55r17?

The height of a 225/55r17 tire is 26.74 inches (679.3 mm), whereas a 215/55r17 tire is 26.31 inches (668.3 mm). Thus, the 225/55r17 tire is approximately 0.43 inches (or 11 mm) taller than the 215/55r17 tire.

How much wider is a 225/55r17 tire than a 215/55r17?

Regarding the width, a 225/55r17 tire measures 8.86 inches (225 mm), and a 215/55r17 tire is 8.46 inches (215 mm) wide. Consequently, the 225/55r17 tire is about 0.39 inches (or 10 mm) wider than the 215/55r17 tire.

Can I use 225/55r17 instead of 215/55r17?

The overall diameter of a 225/55r17 tire is 26.74 inches, and the 215/55r17 tire has an overall diameter of 26.31 inches. The difference between these two tire sizes is roughly 0.43 inches or about 1.6%.

As this is within the acceptable 3% difference, using a 225/55r17 tire instead of a 215/55r17 tire seems plausible. However, it is still advisable to consult with a tire or vehicle expert before making such replacements to ensure optimal safety and performance.

Can I put a 225/55r17 on a 215/55r17?

Both the 225/55r17 and 215/55r17 tires can be fitted on rims within the range of 6.0-7.5″ and 6.0-8.0″ respectively. Therefore, replacing a 215/55r17 tire with a 225/55r17 on the same rim is possible, As the rim width falls within the acceptable range for both tires.

Our Observation
The choice between 215/55r17 and 225/55r17 depends on your driving preferences and conditions. The 225/55r17, with its larger dimensions, provides better traction, ground clearance, and a smoother ride, making it a suitable choice for off-road driving or rough terrains. Its broader rim compatibility also endorses a sportier aesthetic.

Conversely, the 215/55r17, while offering marginally less comfort and traction, provides a higher speedometer reading and might lead to less road noise. Its compatibility with narrower rims lends it a more classic appeal. Furthermore, it’s closer to the typically recommended diameter difference of within 3% from factory-recommended tires, which could mean less adjustment for your vehicle.

Whether you prioritize ride comfort and traction or a sportier aesthetic will determine your choice between these two tire sizes. Matching the tire size to your vehicle’s specifications and driving conditions is essential for the best results. Always consult with a tire expert or your vehicle’s manufacturer when considering a change in tire size.
