About TireBase

TireBase is an independent reference library for tire specifications, standards and science. We exist because tire information online is either marketing copy or forum folklore — and rarely the accurate, sourced middle ground a curious person actually wants.

What we do

We translate dense engineering standards and industry research into guides, calculators and explainers that a non-specialist can use. Every article aims to answer a real question completely — the sort of question that sends people to three unhelpful pages before they give up. We cover passenger and light-truck tires, powersports, bicycles, inner tubes and industrial tires, and we build free browser-based tools for the calculations people repeatedly search for.

How we research

Our source material includes published industry research, national and international standards (GB/T, ISO, ETRTO, ECE, US DOT/FMVSS and UTQG), manufacturer technical documentation, and peer-reviewed materials-science literature. Where figures come from market-research firms we say so, and where estimates differ between sources — as tire market data frequently does — we present the range rather than a false-precision single number.

Our editorial standards
  • We cite the standard or source behind a specification wherever one exists.
  • We show the maths so you can check it, not just trust it.
  • We distinguish measured facts from rules of thumb and from opinion.
  • We flag when data is disputed or when sources disagree.
  • We update articles as standards and products change, and date every revision.

What we are not

We are not a tire manufacturer, retailer or repair shop, and we are not affiliated with any tire brand. Nothing here is a substitute for professional inspection or the specifications on your vehicle placard and in your owner's manual. Tires are safety-critical; when a decision affects safety, consult a qualified tire professional and follow the manufacturer's guidance over anything you read online, including here.

How we make money

TireBase is free to read and supported two ways: display advertising, and affiliate commissions when readers buy through some of our outbound retailer links. Neither influences our editorial content. We choose what to write about based on what readers ask, and we describe products by their specifications, not by what pays best. Full detail is in our affiliate disclosure.

Corrections

We would rather be corrected than be wrong. If you spot an error — a mistyped figure, an outdated standard, a broken calculation — please tell us via the contact page. We correct confirmed errors promptly and note significant changes.
