What are the dimensions for a 265/70R17 tire?

For a 265/70R17 tire, the width is 265mm (10.43in), sidewall height is 185.5mm (7.30in), and overall diameter is 773.1mm (30.44in).

If I switch from 265/70R17 to 285/75R18, what is the speedometer error?

The speedometer error will be approximately -3.45%, meaning your actual speed will be slightly higher than what is shown.

Is a 780mm diameter tire safe to install if my current is 720mm and threshold is 25mm?

The diameter delta is 60mm. This exceeds your 25mm threshold, indicating a High Risk of mechanical interference.

You can use the `calculate_tire_dimensions` tool by providing the metric size, such as '265/70R17'.
