Overall Diameter
The 225/45R17 tire has a larger diameter (24.97 inches) compared to the 215/45R17 (24.62 inches). This 1.4% difference translates into a slight increase in ground clearance, which can be beneficial for off-road driving or navigating over obstacles and rough terrains. However, the increased tire height means a lower speedometer reading, which could affect your driving speeds and fuel economy.

On the other hand, the smaller diameter of the 215/45R17 may reduce the chances of scraping or damaging your vehicle, especially when driving over obstacles. However, its shorter stature could result in higher speedometer readings.

Tread Width
The 225/45R17 has a wider section width (8.86 inches) than the 215/45R17 (8.46 inches), offering a 4.7% increase in tread contact area. This extra width may enhance traction, improving acceleration, braking, and cornering abilities, although it may also produce more road noise due to the larger contact area.

Conversely, the 215/45R17’s narrower tread width means there’s less surface area in contact with the road, which could lead to a reduction in grip, particularly in wet or slippery conditions.

Sidewall Height
With a 4.7% higher sidewall height, the 225/45R17 tire (3.99 inches) offers a slightly smoother ride compared to the 215/45R17 (3.81 inches). The taller sidewall can absorb more road bumps and irregularities, increasing comfort while driving. Moreover, taller sidewalls can increase traction on snowy or icy roads, enhancing the tire’s ability to grip the surface.

The shorter sidewall height of the 215/45R17 might deliver a harsher ride, due to a reduced buffering capacity. However, this might appeal to drivers seeking a sportier and more aggressive look, as smaller sidewalls typically evoke this style.

The 225/45R17 tire features a larger circumference (78.45 inches) than the 215/45R17 tire (77.34 inches), which can result in lower speedometer readings. However, the increased circumference could enhance stability and ride comfort, particularly at high speeds.

The smaller circumference of the 215/45R17 could lead to higher speedometer readings, potentially affecting the perceived speed and fuel efficiency.

Revolutions per Mile

Revolutions per mile

The 225/45R17 tire experiences fewer revolutions per mile (807.61) than the 215/45R17 (819.24). Fewer revolutions mean the tire covers a greater distance per rotation, potentially extending its lifespan by reducing wear and tear. This reduced wear could translate to cost savings over the tire’s lifetime.

The 215/45R17, with more revolutions per mile, may experience increased friction with the road, which could lead to a shorter lifespan due to higher wear.

Rim Size
Both tires fit on a 17″ rim size, but the 225/45R17 can accommodate a slightly wider rim width range (7.0-8.5″) compared to the 215/45R17 (7.0-8.0″). The wider rims associated with the 225/45R17 can provide a sportier look, while the 215/45R17 might offer a more classic appearance due to the narrower rim width range.

How much taller is a 225/45R17 tire than a 215/45r17?
