Maximum roll angle before risking rollover (off-roading)

[shinysideup2]

Hi. Would any of you with off-roading experience in your 3rd/3.5 gen (2007-2017) know how far you can raise one side of the vehicle (e.g. while traversing rocky terrain) before risking rollover?

I have a lifted '96 4-Runner 4wd which I frequently take off-road. It took me quite some time to get comfortable with how far it can lean to one side on rutted/rocky terrain without it rolling over (quite a few "oh shit" moments).

Some 3rd gen Expeditions have roll/pitch/steering angle gauges integrated into the instrument cluster. Wondering if anybody has taken notice of any extreme roll angles while off-roading without rolling over (or with!).

Thanks.
Jay.

Its not the angle, its where the CG (center of gravity) is. You'll roll at a lower angle if you have, say, a spare tire on your roof.

If you draw a vertical line (relative to gravity/local horizontal) from the outside edge of your tires up to infinity, those lines are your "limit". Then, you'd have to know where the CG of your vehicle is AT THAT INSTANT IN TIME. When you roll, you'll be stable until the CG exceeds those vertical lines. Then you will roll. Your CG changes all the time due to passengers, cargo, fuel, etc...anything that changes the total weight.

Tons of factors

Differences in wheels and tires alone can be 150-200 lbs of weight below the center of gravity

How tight or loose your coilovers and sway bars are also changes everything... if there's lots of travel, then most of your sprung weight is partially reoriented if your wheels are angled on an incline

Tight suspension, otoh, allows very little of that

It's funny that the op's handle is shinysideup lol

i think the max tilt or roll angle is the one right before the uphill side breaks free of the ground,
to many variables to list a particular angle,

in other trucks i used the "i dont feel comfortable anymore as a sign to turn down hill
