    I have a heavy, modified tactical off-road vehicle, with significant changes to the Center of Gravity (CG) and weight from the original engineering data sheet. Is there a free online/website calculator/tool that can be used to calculate a vehicle's risk of rollover (or provides estimates of limits) based on factors such as:


    - CG

    - CG height over ground

    - Vehicle weight (variable based on passenger load)

    - Axle separation

    - Speed

    - Acceleration/deceleration

    - Surface type (asphalt, loose dirt, packed dirt)

    - ascent/descent/side slope grades

    Good question. A 'risk of rollover' app would have liabilities, whether or not something went wrong. I know of no engineer who would put their reputation on the line as to any vehicle's ultimate 'tipping point'.
    A mechanical engineer may have some pointers and there is some 'common sense' guidelines. There are likely a few more variables and possible unknowns to the equation than you stated.

    We actually do publish tipping loads in my line of work (construction equipment), the rated operating load of a wheel loader, tractor-loader-backhoe or skid-steer loader is generally 50% of the load that makes the machine tip forward.

    The calculators that I know of are proprietary since they need to account for the kinematics of the lift arm linkages.
