About FitmentCompass
FitmentCompass helps drivers understand tire sizes, wheel specifications, vehicle fitment, and compatibility without making the process unnecessarily complicated.
Our goal is to bring useful fitment information, calculators, comparisons, and practical guides together in one place so you can research the right setup for your vehicle with more confidence.
What We Cover
FitmentCompass focuses on the information drivers commonly need when researching tires and wheels, including OEM tire sizes, alternative sizes, wheel dimensions, bolt patterns, offsets, backspacing, tire pressure, speedometer changes, and general compatibility.
We also build calculators and comparison tools designed to make technical specifications easier to understand. Instead of showing numbers without context, we aim to explain what those numbers mean and how changes may affect fitment.
How We Research Fitment Information
Our content is created through research and comparison of available vehicle, tire, and wheel specifications. When preparing fitment pages and guides, we aim to verify important specifications against reliable sources whenever possible, including manufacturer information, technical documentation, established fitment references, and other relevant data sources.
Vehicle specifications can vary by model year, trim, market, drivetrain, wheel package, and factory option. For that reason, FitmentCompass is intended as a research resource rather than a replacement for the vehicle manufacturer, tire manufacturer, wheel manufacturer, or a qualified tire and wheel professional.
Our Calculators
FitmentCompass tools are designed to help users compare measurements and understand how tire or wheel changes may affect a vehicle. Examples include tire size comparisons, overall diameter calculations, speedometer differences, wheel offset, backspacing, and other fitment-related measurements.
Calculator results are informational estimates based on the values entered. Real-world compatibility may also depend on suspension components, brake clearance, wheel design, vehicle modifications, load requirements, and other factors that cannot always be determined from basic dimensions alone.
Clear Information Without Unnecessary Claims
We believe automotive information should clearly distinguish between researched specifications, calculated results, manufacturer information, and actual hands-on experience.
FitmentCompass does not claim that a tire, wheel, or vehicle setup has been physically tested unless we specifically state that such testing occurred. Most of our content is based on specification research, data analysis, comparison, and editorial review.
How We Handle Recommendations
Some FitmentCompass pages may include links to compatible products or retailers. When we discuss or compare products, our aim is to provide useful information about specifications, compatibility considerations, features, and potential applications rather than simply promoting the most expensive option.
Some links may be affiliate links. If you make a purchase through one of those links, FitmentCompass may earn a commission at no additional cost to you. Affiliate relationships do not change the specifications we report or the way we explain fitment information.
Our Editorial Team
FitmentCompass content is prepared and reviewed by the FitmentCompass Editorial Team. Our editorial process focuses on clear explanations, consistent terminology, useful comparisons, and careful handling of technical specifications.
As the site grows, we will continue expanding our vehicle database, tire-size resources, wheel-fitment information, calculators, and educational guides.
Accuracy and Updates
Automotive specifications and product information can change, and errors are possible even when information is carefully researched. We periodically review and update content when new information becomes available.
Before purchasing tires or wheels, confirm critical specifications for your exact vehicle, model year, trim, and configuration. When in doubt, consult the vehicle manufacturer or a qualified tire and wheel professional.
