What It Is

Tire Size (tiresize.co.kr) appears, based on the crawled content, to be a Korean-language web tool from Korea. Its positioning is closer to an online tire size calculator from a “tire lab” than a conventional enterprise SaaS product. It mainly helps users compare the outside diameter difference between an original tire and a new tire after changes to section width, aspect ratio, and rim size, and assists in judging whether a wheel upgrade or tire replacement size is reasonable.

Core Features

The page provides inputs for the original size and the new size, including section width, aspect ratio, and inches. After clicking “Calculate,” users receive an outside diameter comparison analysis. One practical feature is that if users do not know the full target tire specification and only enter the rim size they want to switch to, the tool can calculate “recommended sizes.” The recommendation logic displays sizes within ±3% of the original tire’s outside diameter and shows the speedometer error based on 100km/h. The page also displays recent calculation results, making it easy to see common combinations used by other visitors.

Pricing and Enterprise Capabilities

The crawled text does not mention plans, pricing, paywalls, account systems, or trial information, so its business model cannot be confirmed. There is also no information about third-party integrations, team collaboration, permission management, APIs, developer documentation, data security compliance, or private deployment. Judged by SaaS/enterprise software standards, it lacks multi-user management, enterprise workflows, data governance, and system integration capabilities. It is more like a free public utility page.

Pros and Cons

Its advantages are that it has a low barrier to use, and selection-based inputs reduce formatting errors. The recommended size feature provides practical reference value for wheel upgrades and tire replacements. The page also clearly states that recommended sizes may include specifications that are not actually sold, and that it assumes no responsibility for property damage or accidents resulting from use of the calculation results, making the risk boundaries relatively clear. Its drawbacks are that the feature scope is narrow, and it lacks deeper capabilities such as accounts, saved projects, a vehicle model database, and integration with shop inventory. The calculation results should only be used as a reference and cannot replace professional fitment confirmation.

Who It’s For and Access from China

It is suitable for car owners, car modification enthusiasts, tire shops, and repair technicians who need to quickly calculate sizes during preliminary selection. Access from China cannot be determined from the text and should be marked as unknown. Because the site is Korean and the language is Korean, Chinese users may face uncertainty around language and cross-border network experience. Payment information is not disclosed. Alternatives include tire calculators offered by domestic automotive communities, tire e-commerce platforms, or modification forums.
