Helpful to include

• The page address (URL) and the numbers you entered.
• What you expected to see, and where that figure comes from (tire maker’s spec sheet, measured tire).
• Your device and browser if something looks broken.

We read every message and fix confirmed errors quickly. We can’t confirm fitment for a specific vehicle; for that, please ask a tire shop or the vehicle maker.
