About MyWheelOffsetCalculator.com

MyWheelOffsetCalculator.com was founded by automotive engineers, track enthusiasts, and mechanics tired of vague, inaccurate forum fitment advice. We built a modern, responsive suite of precision calculators engineered to remove the guesswork from buying aftermarket wheels and tires.

Mathematical Rigor

Every calculation—from inner strut clearance deltas to revolutions per mile—is computed using pure geometric formulas verified against ISO tire standards and SAE J175 wheel guidelines.

Zero Generic Content

Our guides and vehicle specs are written and reviewed by automotive specialists. We provide real worked numbers, torque specs, and troubleshooting techniques tested in real garages.

100% Free & Independent

We are not owned by a wheel distributor or tire conglomerate. Our recommendations prioritize safety, mechanical reliability, and proper suspension geometry above all else.

Our Engineering Process

Before publishing any tool or vehicle fitment specification on our platform, our team follows a rigorous 3-step verification process:

Factory OEM Service Manual Cross-Check: We verify factory wheel widths, offsets, bolt patterns (PCD), center bores, and lug hardware thread sizes against official OEM workshop service literature.
Mathematical Modeling: All clearance formulas are coded as pure, typed functions and tested against unit test suites covering edge cases from extreme negative truck offsets (-44 mm) to ultra-high European offsets (+60 mm).
Community Real-World Validation: We review real-world fitment data from verified owner builds across forums, track days, and off-road clubs to document known caliper clearance issues, fender liner rub spots, and suspension nuances.
