Terms of use
4wd.ai provides research and calculation tools for planning. It does not inspect your vehicle or approve a modification.
No installation guarantee
Fitment depends on manufacturing tolerance, tire construction, alignment, load, wear, component combination and installation quality. You must verify clearance with a qualified installer before driving.
Safety responsibility
Vehicle modifications can affect steering, braking, electronic driver-assistance systems, payload, legal compliance and warranty coverage. Follow manufacturer instructions and applicable laws. Stop using a configuration that contacts safety-critical components.
Calculations
Calculator results use theoretical dimensions and should be treated as estimates. Actual tire measurements and speedometer behavior may differ.
