Welcome to Fitment Calculator.
These Terms and Conditions govern your use of https://fitmentcalculator.com/, including its calculators, articles, guides, diagrams, tools, and other content.
By accessing or using the website, you agree to these Terms and Conditions. If you do not agree with these terms, you should discontinue use of the website.
Website Purpose
FitmentCalculator.com provides informational and educational resources concerning wheels, tires, wheel offset, backspacing, tire dimensions, speedometer changes, and related automotive measurements.
The website includes calculators intended to help users compare dimensional differences between configurations.
The website is not a vehicle inspection service, engineering certification service, tire installer, wheel installer, repair facility, manufacturer, or government authority.
Calculator Results
Calculator results are based on mathematical formulas and the information entered by the user.
Results are theoretical estimates.
They should not be interpreted as a guarantee that a particular wheel or tire combination:
- Will physically fit a specific vehicle
- Is safe to use
- Is legal in a particular jurisdiction
- Is approved by a vehicle manufacturer
- Is approved by a wheel manufacturer
- Is approved by a tire manufacturer
- Has adequate brake clearance
- Has adequate suspension clearance
- Has adequate body or fender clearance
- Will not rub during steering or suspension movement
- Has an appropriate load or speed rating
Users are responsible for verifying real-world compatibility before purchasing, installing, modifying, or operating any wheel, tire, spacer, or related component.
User Input
The accuracy of calculator output depends on the accuracy of the information entered.
You are responsible for checking measurements, tire markings, wheel specifications, units, and other values before relying on a calculation.
Entering incorrect information may produce incorrect or misleading results.
Tire and Wheel Variations
Actual tire and wheel dimensions may differ from nominal or advertised specifications.
Factors may include:
- Tire manufacturer
- Tire model
- Rim width
- Inflation pressure
- Tire wear
- Manufacturing tolerances
- Wheel-flange dimensions
- Measurement method
Calculator outputs should therefore be used as a comparison or planning aid rather than as a substitute for physical measurement.
