Contact TreadSize

We read every message sent to hello@treadsize.com.

What to include

• Data corrections: if you spot a calculation error, include the tire size, what the tool showed, and what you believe the correct value should be (with a source if you have one).
• Guide feedback: link to the guide page and describe the section.
• General questions: fire away — we will respond as time allows.

Response time

We typically respond within 2–5 business days. We do not offer real-time tire fitment advice — for that, please consult a local tire professional who can inspect your vehicle directly.
