How do I prevent rollovers when driving an SUV?

Wear your seatbelt. Starting with the obvious, seatbelts reduce your risk of serious injury by a whopping 50%.
Go with a newer vehicle. Manufacturers are constantly updating SUV designs to make them safer to drive, so newer models tend to be safest.

Pro Tip: The wider the space between your back wheels, the more stable the SUV.

Know your car. Get familiar with your vehicle and how to handle it before going on any risky roads. SUVs have higher centers of gravity, so turning, steering, accelerating, and braking may take some time to get used to.
Always check your tires. Due to their higher centers of gravity, SUVs can destabilize easier. If your tires are under-inflated or unevenly inflated, your whole vehicle could lose balance.
Avoid overloading. SUVs are great for space, but be careful not to overdo it. Try to pack heavier things on the floor and closer to the center—and steer clear of packing things on the roof whenever possible.

Bonus tip: Watching your speed, considering road conditions, and keeping a firm grip on the steering wheel can all help to prevent rollovers. And no panic steering!
