LS vs. Hemi vs. Coyote Builds and Examples 205 or 215mm: 225mm: 7.5 Inch: 205mm: 215 or 225mm: Proper Tire Fitment vs Too Wide vs Too Narrow Both in the table and in the graph, the tires are compared according to the following indicators: overall diameter, section width, circumference, sidewall height and clearance. Also, the online application calculates the difference in real speed and speedometer readings if the difference between tire 225/55 R17 and tire 225/50 R17 is significant. One wheel can hold a range of widths, so you might be able to go from 205 to 225 to run a wider tire (more rubber on the road, creates a larger contact patch and so theoretically more traction) but you would need to reduce the sidewall percentage to 50 to keep the height of the sidewall close to the same (112.75mm vs 112.5mm). The 205/55 tire has a diameter of 631.9 mm or 24.878 inches. The 225/50 tire has a diameter of 631.4 mm or 24.858 inches. That's close enough to call it even. However, the 205 tire has a width of 8.071 inches while the 225 tire has a width of 8.858 inches. That's about a 10% increase. The main difference between 205 and 225 tires is their size and dimensions. A 205 tire is narrower than a 225 tire, measuring 205mm across the tread. A 225 tire is slightly wider, measuring 225mm across the tread. This extra width helps the 225 tire to provide more grip and traction, which is beneficial when cornering or accelerating. And since tires have two sidewalls, one on top and one on the bottom, the total height difference between the full 255 tires and 225 tires is double that per-sidewall difference. So, with identical 70 aspect ratios, the overall height of a 255 tire would be 42 mm more than a 225 tire (2 x 21 mm). a0OXm. 225/75-R15 tires are 2.18 inches (55.4 mm) larger in diameter than 205/75-R14 tires and the speedometer difference is 7.7%. 215/60-R16 tires are 0.67 inches (16.9 mm) larger in diameter than 205/65-R15 tires and the speedometer difference is 2.5%. *Assuming tires are only used in the winter season, which is defined as approximately from mid-October to mid-April (6 months for very cold regions), and that an average user would go about 1,200 miles per month, the Bridgestone Blizzak™ WS90 would last an extra winter season vs. the Bridgestone Blizzak™ WS80 tire. Kumho - 25". Michelin - 24.7". Cooper - 25". General - 25.1". All the tire sizes are very close in diameter. But visually, both the Michelin and Cooper tires look shorter than the other two since the Kumho and General are brand new. The Michelin tire probably has around 5k to 6k miles whereas the Cooper is close to the end of its tire life. 285/55r20 vs 285/65r20. 285/65r20 vs 33/12.50r20. 305/55r20 vs 35/12.50r20.
