Larger Tire Profile:
Installing tires with a larger profile (e.g., going from a 205/60R16 to a 225/65R16) will generally increase the overall diameter of the tire. This increase in diameter effectively raises the vehicle's ride height, making it sit higher off the ground.
Smaller Tire Profile:
Conversely, switching to tires with a smaller profile (e.g., from a 225/60R17 to a 215/55R17) will reduce the overall tire diameter. This decrease in diameter lowers the vehicle's ride height, bringing it closer to the ground.
Aspect Ratio:
The aspect ratio of a tire, represented by the number after the tire width (e.g., 65 in "225/65R16"), indicates the tire's sidewall height as a percentage of its width. A higher aspect ratio (e.g., 65) means a taller sidewall, while a lower aspect ratio (e.g., 55) means a shorter sidewall. Changing the aspect ratio can impact ride height accordingly.
It's important to note that altering tire size can have other effects on your vehicle's performance and handling. Changes in overall diameter, width, and aspect ratio can affect factors like speedometer accuracy, suspension geometry, ground clearance, and overall vehicle dynamics.
Before changing your tire size, it's always a good idea to carefully consider the intended purpose and consult your vehicle's manufacturer guidelines or a qualified mechanic. This ensures that any modifications made are safe and appropriate for your specific vehicle.
