The RTI is the distance, in inches, that you can drive your vehicle with one wheel on a 20-degree ramp without lifting any other wheel off the ground. This distance up the ramp divided by the wheelbase of the vehicle and multiplied by 1,000 is the RTI. This vehicle has an RTI of 429 (connected sway bar) or an RTI of 538 (disconnected sway bar), which means you can articulate one front wheel 22 inches (56 cm) or 27.5 inches (70cm) in the air while the other three wheels remain in contact with the ground.
