About Treadsley
Treadsley is being built as a clean, engineering-first tire reference site.
What Treadsley is for
Treadsley provides practical tire reference tools for people who want clear calculations without ad clutter, affiliate noise, or fake precision.
What makes it different
The goal is to build tools that are useful, conservative, and transparent about their limits. Tire size comparisons, tread-depth calculations, pressure conversions, and wear-rate estimates should help users understand the numbers, not pretend to replace vehicle manufacturer guidance or professional tire inspection.
Important limitation
Treadsley tools are informational only. Tire safety, legal compliance, fitment, load capacity, inflation pressure, and serviceability depend on vehicle-specific and region-specific requirements.
