Tire sizes are specified in a format like "225/45R17", where 225 is the width in millimeters, 45 is the aspect ratio (height as a percentage of width), and 17 is the wheel diameter in inches. Changing tire sizes can affect vehicle handling, speedometer accuracy, and overall performance. It's crucial to choose compatible sizes that maintain proper clearance and don't significantly alter the original specifications.
Generally, it's recommended to stay within 3% of the original tire's overall diameter. Larger differences can affect vehicle handling, speedometer accuracy, and safety systems. Always consult your vehicle manufacturer's specifications and a tire professional.
Yes, changing tire diameter affects speedometer readings. Larger diameter tires make the speedometer read slower than actual speed, while smaller tires make it read faster. Each 1% change in diameter results in approximately 1% speedometer error.
