Every other wheel fitment site is plastered with ads, paywalls, and upsells. WillItRub gives you professional-grade tools for free — because buying the wrong wheels is expensive enough.
Buying aftermarket wheels is one of the most common modifications in the car community — and one of the easiest to get wrong. Order a set with the wrong offset or width, and you're looking at fender rubbing, suspension contact, brake clearance issues, or a set of wheels you can't return. Most people get fitment advice from forums full of conflicting claims, paid databases with monthly subscriptions, or shops that only help if you're buying from them.
We built WillItRub to be the tool we wished existed: free, fast, honest about fitment constraints, and designed by people who've actually bought wheels that didn't fit. You can check fitment, compare tire sizes, find bolt patterns, and understand the impact of different setups — all without creating an account or paying a subscription.
WillItRub uses real vehicle specifications from the NHTSA Vehicle Identification Number (VIN) database combined with manufacturer wheel and tire data. You input your vehicle model and year, select your proposed wheel and tire size, and adjust suspension height if you're lowered or lifted. The calculator then compares the proposed fitment against stock clearances, showing you potential rubbing points, suspension contact risk, and speedometer impact.
The calculator provides guidance and estimates — not guarantees. Every vehicle is unique, suspension geometry varies by trim level and manufacturing run, and installation quality matters. We always recommend test fitting in person before committing to a purchase and consulting with a shop if you're unsure about your specific setup.
Vehicle specifications: NHTSA Vehicle Identification Number (VIN) database and manufacturer technical specifications. We maintain records for 200+ popular vehicle models covering sedans, coupes, SUVs, trucks, and performance platforms.
Wheel and tire data: Manufacturer specifications from wheel makers and tire companies. We track fitment across multiple wheel brands and tire manufacturers to provide realistic fitment scenarios.
Community data: Real-world fitment reports from users who have tested specific wheel and tire combinations on their vehicles. Community feedback helps us identify fitment surprises and understand how different suspension setups affect actual clearance.
WillItRub aggregates published specifications and community feedback to provide fitment estimates. We make every effort to maintain accurate data, but errors can occur. Vehicle specifications may vary by production run. Suspension geometry differs between trim levels. Wheel manufacturing tolerances exist. Installation quality affects actual fitment.
The calculator provides guidance for making informed decisions — not engineering-grade precision. A fitment that calculates as "will fit" might still rub on your specific vehicle depending on suspension setup, ride height, and wheel manufacturing specs. A fitment that shows potential contact might work fine with proper installation. Always verify fitment in person on your actual vehicle before making a purchase.
If you discover incorrect data — a vehicle specification error, an inaccurate wheel measurement, or a problematic fitment outcome — please report it so we can investigate and update our records.
WillItRub is published by CMBMV LLC, an independent media company. We are not affiliated with any wheel shop, tire retailer, wheel manufacturer, or aftermarket brand. We don't sell wheels. We don't take commissions based on fitment recommendations. We build tools that help car enthusiasts make smarter purchasing decisions.
Our team includes people who've bought wheels that didn't fit, had to resell them at a loss, or dealt with the frustration of finding out too late that a setup won't work. We built this tool to help others avoid that experience.
WillItRub is supported by advertising and affiliate relationships. When you click a link to a wheel retailer or tire shop, we may earn a commission if you make a purchase. These commissions help fund the site and allow us to keep the tools free. We only affiliate with retailers we believe offer good value and service.
Affiliate relationships never influence our fitment calculations, accuracy, or recommendations. We recommend you shop around, compare prices, and read retailer reviews — just like you would anyway.
