The information, calculators, tools, diagrams, examples, and other content available on https://fitmentcalculator.com/ are provided for general informational and educational purposes.
By using Fitment Calculator, you acknowledge the limitations described in this Disclaimer.
Wheel and Tire Calculator Disclaimer
Calculations provided by FitmentCalculator.com are theoretical dimensional estimates based on mathematical formulas and user-supplied information.
Calculator results do not constitute a guarantee that any particular wheel, tire, spacer, or vehicle modification will physically fit, operate safely, comply with manufacturer specifications, or comply with applicable laws.
Physical Fitment Cannot Be Confirmed Online
Fitment depends on factors that cannot be fully determined using wheel and tire dimensions alone.
FitmentCalculator.com cannot physically verify:
- Brake-caliper clearance
- Suspension or strut clearance
- Fender clearance
- Inner body clearance
- Clearance at full steering lock
- Clearance during suspension compression
- Bolt pattern
- Centre bore
- Wheel hardware
- Wheel load capacity
- Tire load index
- Tire speed rating
- Manufacturer tire approval
- Actual mounted tire dimensions
- Vehicle modifications
- Alignment settings
- Local roadworthiness or modification laws
Therefore, calculator results should be considered a starting point for comparison and verification, not proof of compatibility.
Actual Measurements May Differ
Tire sizes printed on a sidewall are nominal sizes.
Actual dimensions can vary between manufacturers, tire models, rim widths, pressures, and manufacturing tolerances.
Similarly, wheel dimensions and measured backspacing may differ depending on how and where measurements are taken.
Real-world measurements should be used whenever precise clearance is important.
Speedometer Calculations
Speedometer calculations on this website estimate the theoretical difference caused by changes in tire diameter.
Actual vehicle speedometer behavior may be affected by vehicle electronics, calibration, tire pressure, tread wear, manufacturer tolerances, drivetrain characteristics, and other factors.
A calculated speed difference should not be treated as an official calibration.
Percentage Difference Guidelines
Any percentage ranges, comparison indicators, caution states, or similar guidance presented by FitmentCalculator.com are intended to help users understand dimensional differences.
They are not universal safety limits, legal limits, manufacturer approval thresholds, or engineering certifications.
Vehicle manufacturers and tire manufacturers may have their own requirements.
Professional Advice
FitmentCalculator.com does not provide professional mechanical, engineering, legal, or vehicle-safety advice.
Before installing non-standard wheels, tires, spacers, suspension components, or related parts, consider consulting:
- The vehicle manufacturer
- The wheel manufacturer
- The tire manufacturer
- A qualified tire professional
- A qualified automotive technician
- An appropriately qualified engineer where required
- Relevant local authorities when legal compliance is uncertain
User Responsibility
You are responsible for verifying specifications and determining whether a wheel, tire, or modification is appropriate for your vehicle.
Do not purchase, install, or operate components solely because an online calculator produces a favorable result.
Always physically verify critical clearances and specifications.
Accuracy of Information
We make reasonable efforts to provide useful calculations and educational information.
However, FitmentCalculator.com does not warrant that every calculation, article, formula explanation, example, diagram, link, or other piece of information will always be complete, error-free, or current.
