Comparing Diameters
When comparing tire sizes, it’s essential to understand how the width affects the overall diameter. While the width increases from 275 to 285, the aspect ratio plays a crucial role in determining the tire’s diameter. The aspect ratio represents the tire’s height as a percentage of its width. Let’s consider an example to illustrate this:
- 275/40R20: Assuming a 275mm width and 40% aspect ratio, the sidewall height can be calculated as follows:
- 275mm (width) * 0.40 (aspect ratio) = 110mm (sidewall height)
- 110mm (sidewall height) * 2 (two sidewalls) = 220mm (total sidewall height)
- 220mm (total sidewall height) + 508mm (rim diameter converted to millimeters) = 728mm (total tire diameter)
- 285/35R19: Assuming a 285mm width and 35% aspect ratio, the sidewall height can be calculated as follows:
- 285mm (width) * 0.35 (aspect ratio) = 99.75mm (sidewall height)
- 99.75mm (sidewall height) * 2 (two sidewalls) = 199.5mm (total sidewall height)
- 199.5mm (total sidewall height) + 482.6mm (rim diameter converted to millimeters) = 682.1mm (total tire diameter)
Based on these calculations, the 275/40R20 tire has a slightly larger diameter (728mm) compared to the 285/35R19 tire (682.1mm). It’s crucial to consider this difference in diameter as it can affect various aspects of your vehicle’s performance.
