Effective date: June 26, 2026

Overview

These Terms of Use govern use of Treadsley.com, including consumer tools, calculators, educational resources, generated reports, website content, and related features. By using this website, you agree to these terms. If you do not agree, do not use the website or its tools.

Treadsley is a brand operated by Treadsley Holdings LLC.

Consumer Tools and Generated Reports

Treadsley consumer tools, calculators, educational resources, and generated reports are provided solely for personal, non-commercial, informational, and educational use.

These tools are not intended for commercial decision-making, engineering analysis, fleet management, product validation, regulatory compliance, safety inspections, fitment approval, warranty determinations, or any other commercial or professional application.

Unless specifically provided as part of a separate written testing or consulting agreement with Treadsley Holdings LLC, tool outputs do not constitute independent testing, engineering services, professional advice, product certification, regulatory approval, or recommendations by Treadsley.

Organizations requiring commercial testing, engineering support, independent validation, customized analysis, or commercial reporting should contact Treadsley regarding professional testing and consulting services.

Generated reports and tool outputs may not be resold, redistributed, republished, incorporated into commercial testing deliverables, represented as independent testing performed by Treadsley, or otherwise used for commercial purposes without the prior written permission of Treadsley Holdings LLC.

No Safety, Legal, Fitment, or Inspection Approval

Treadsley consumer tools do not determine whether a tire, wheel, vehicle, component, or product is legal, safe, roadworthy, serviceable, properly fitted, acceptable for continued use, or compliant with inspection requirements.

Tool outputs are not legal advice, safety advice, inspection results, fitment approval, maintenance approval, product approval, or a substitute for professional evaluation by a qualified service provider.

Users remain responsible for complying with all applicable federal, state, provincial, territorial, local, and country-specific laws, regulations, inspection rules, and operating requirements.

Manufacturer and Professional Recommendations

Vehicle manufacturers, tire manufacturers, component manufacturers, fleet operators, regulatory authorities, and inspection programs may establish requirements that differ from assumptions used by Treadsley tools.

Before making decisions regarding tire replacement, continued service, vehicle operation, repairs, fitment, load capacity, inflation pressure, maintenance, or product use, users should consult the applicable manufacturer instructions, owner materials, service documentation, and an authorized manufacturer representative or qualified professional.

Tool Assumptions and User Responsibility

Some tools use fixed assumptions for calculation purposes. For example, unless otherwise specified, tire wear tools may use a treadwear reference of 2/32 inch or 1.6 mm for calculation purposes only. That reference does not determine legal minimum tread depth, roadworthiness, safety, serviceability, or acceptability in any location or application.

Actual tire life, wear rate, serviceability, and product performance may vary based on driving style, alignment, inflation pressure, rotation practices, vehicle load, road surface, climate, tire construction, tread compound, weather, damage, age, measurement consistency, operating conditions, and other factors.

Visible tire damage, cracking, bulges, exposed cords, punctures, abnormal wear, vibration, air loss, or other unusual conditions should be inspected by a qualified tire professional to help determine continued serviceability.

Users are responsible for verifying all measurements, inputs, assumptions, and results before relying on any information generated by the website.

Unsupported Applications

Unless a tool specifically states otherwise, Treadsley consumer tire tools are not intended for motorcycle, powersports, specialty trailer, aviation, racing, off-road-only, industrial, agricultural, or other specialty applications. These applications may involve different requirements, risks, service conditions, and inspection standards.

No Professional or Contractual Relationship

Use of this website, consumer tools, educational resources, generated reports, or submission of a contact request does not create a testing agreement, consulting engagement, engineering relationship, confidential relationship, fiduciary relationship, or other contractual relationship with Treadsley Holdings LLC.

Testing services, consulting services, test article acquisition, and other professional services are provided only under separate written agreements.

User Submitted Information

Users should not submit confidential, proprietary, export-controlled, regulated, sensitive personal, or restricted information through Treadsley consumer tools or general website forms unless specifically authorized under a separate written agreement.

Unless specifically requested as part of a contracted testing program, users should not enter vehicle identification numbers (VINs), license plate numbers, driver names, customer names, addresses, telephone numbers, email addresses, or other information that directly identifies an individual into consumer tools.

By submitting information through the website, you represent that you have the right to submit that information and that your submission does not violate the rights of another person or organization.
