- Worth noticing
- The excerpt cites both 387 and 978 listed sizes, so the chart’s stated coverage count is unclear.
Field notes
The calculator accepts sidewall formats such as 265/70R17 and 33x12.50R17, then displays dimensions in inches and millimeters. Comparison outputs include speedometer difference and ground clearance; the page also links six tools that it says carry entered numbers between tire sizing, wheel fitment, and gear-ratio calculations. Its coverage count is inconsistent in the excerpt, which cites both 387 and 978 sizes.
