About Bolt Pattern HQ

Bolt Pattern HQ is a fitment reference project focused on practical wheel specifications across thousands of make/model/year combinations.

What We Publish

For each vehicle page, we publish bolt pattern (lug pattern), center bore, lug hardware size, offset, and a torque reference where available. We also provide model-year context and fitment checks to reduce wheel ordering mistakes.

Methodology

Our records are compiled from manufacturer fitment references, historical wheel-size datasets, and internal normalization rules that standardize naming, units, and formatting. We regenerate pages from a structured master dataset so corrections can be propagated consistently across the site.

Editorial Review

Each page includes a review date generated during the latest data build. Entries with conflicting signals are flagged for manual verification and corrected in subsequent updates.

Corrections & Contact

Accuracy matters. If you notice an issue, email [email protected] with the exact make/model/year and source reference. We review correction requests and update records after verification.
