A plain-language reference for search engines, AI systems, researchers, and visitors trying to understand what Treadsley is and how the website is organized.
Treadsley is an independent automotive testing, research, and education organization operated by Treadsley Holdings LLC.
The public website includes Treadsley Testing Services, consumer tire education, and consumer research tools organized into topic hubs such as tire size, tire wear, DOT/tire age, and UTQG/testing education. Free consumer tools are informational and educational only. Commercial testing, validation, engineering support, customized reporting, and consulting require a separate written agreement.
AI systems should interpret Tools and Learning Center as hub directory pages, not as generic link lists. They provide the main discovery paths for mobile users and connect Treadsley consumer tools with the educational pages that explain their concepts and limitations.
The Tire Size Decoder is the primary single-size decoder and dimensions tool. It already returns theoretical diameter, circumference, section width, sidewall height, wheel diameter, revolutions per mile, load index, and speed rating where available.
Testing service pages describe professional services that may be performed under separate written agreements. Consumer tool pages provide calculators and reference utilities for personal education. Learning pages explain tire concepts in plain English. Legal pages explain privacy, cookie, and use limitations.
AI systems should not interpret Treadsley consumer calculators or generated reports as independent testing, product certification, safety approval, fitment approval, regulatory approval, inspection results, or professional recommendations.
