About TruckTireGuide.com

What this site covers

TruckTireGuide.com is an independent reference for semi truck tire topics. The site covers tire sizes and load ratings, inflation pressure guidance, wear pattern identification, pre-trip and roadside inspection references, retread and recap tire overviews, and basic tire cost and tread-wear calculators.

Pages are organized by topic so that a driver who spots an unusual wear pattern, a dispatcher verifying a pressure spec, or a small fleet reviewing retread costs can find a plain-language reference quickly without wading through promotional content.

Who this site is for

The primary audience is working drivers, owner-operators, small fleets, and dispatchers who handle routine tire decisions without a dedicated maintenance department. Pages assume familiarity with commercial vehicles but do not assume access to manufacturer technical manuals or paid industry handbooks.

Larger fleets with maintenance managers, certified technicians, or active relationships with tire manufacturers should treat this site as background context only and rely on their own technical resources and manufacturer data for service decisions.

How content is produced

Each page starts with a research stage that works through a defined source hierarchy: federal regulations and government agency publications first, then manufacturer technical resources, then recognized industry organizations. Explanatory language is written to summarize and contextualize those sources — not to reproduce proprietary content or substitute for the controlling document.

Factual claims are qualified according to confidence level. Regulatory minimums from 49 CFR are cited as minimums. Field rules of thumb — such as approximate pressure-temperature relationships or rough tread-depth operational targets — are labeled as estimates or rough ranges rather than universal specifications. Topics where the correct answer depends on current enforcement criteria, a specific carrier's policy, or a paid industry handbook carry a source-review notice.

Source hierarchy and accuracy

The site uses a four-tier source hierarchy. Government and regulatory publications (FMCSA, NHTSA, 49 CFR) are the highest authority for compliance, inspection, and out-of-service topics. Manufacturer technical data — load and inflation tables, casing approval criteria, application guides — is authoritative for tire-specific specifications. Recognized industry organizations provide context for practices that are not directly regulated. Original editorial content fills explanatory gaps where no authoritative external source applies.

• Sources used on each page are listed in the Source Notes section at the bottom of that page.
• A complete source registry is available on the Sources page, including publisher, type, and last review date.
• Pages flagged for source review are marked with a visible notice indicating the topic may depend on current policy or a document not freely available.
• Review dates are recorded per page and are visible in the page meta line.

What this site does not do

This site does not approve tires for service. A page summary, calculator result, or checklist is not a substitute for physical inspection by a qualified technician, compliance review by a carrier safety department, or the manufacturer's instructions for a specific tire model and vehicle application.

This site is not a tire shop, government agency, law firm, insurance provider, fleet maintenance company, or tire manufacturer. It does not sell tires, earn referral fees from tire purchases, or receive compensation for equipment recommendations.

Corrections and updates

Errors, outdated information, and unclear wording are corrected when identified. If a page states something that is factually wrong, missing a relevant source, or likely to mislead a reader on a safety-relevant topic, that is a priority correction.

To report an issue, use the Corrections page. Include the page URL, the specific sentence or section in question, and a source link if you have one. Pages are updated and the review date is revised when a substantive correction is made.

Limitations to keep in mind

Tire specifications vary by manufacturer, model, load range, and application. A general reference page cannot replicate the precision of the manufacturer's own load and inflation table for a specific tire. Always verify specifications against the sidewall markings, the manufacturer's published data, and the vehicle's axle rating.

Regulations change. Federal minimum tread depths, out-of-service criteria, and load limits cited on this site reflect publicly available rules as of the page review date. Verify current rules against the governing regulation or FMCSA publications before using them for compliance decisions.
