This conversion is essential when comparing tire sizes and ensuring they are appropriate for your vehicle.
How Does the Aspect Ratio Affect Performance?
The 75 aspect ratio in 225/75R16 means the tire’s sidewall height is 75% of its width. A higher aspect ratio, such as 75, typically indicates a taller sidewall, which impacts ride comfort and handling.
- Higher Aspect Ratio (75): Provides better cushioning and comfort, especially on rough roads.
- Lower Aspect Ratio (65 or 55): Offers improved handling and performance, particularly at higher speeds, but can result in a firmer ride.
Balancing Comfort and Performance
The 75 aspect ratio strikes a balance, offering both comfort and stability. It’s ideal for trucks and SUVs, as it helps absorb shocks while maintaining a level of handling suited for both city driving and off-road use.
