The owner’s manual typically tells where to place the jack. In any case, I recommend using a platform as already illustrated. This adds stability and keeps it from sinking into the ground.

The first thing you’re likely to discover is that the jack won’t fit under the 4X at the flat tire. Here’s another one of those things that’s too simple to teach and best told with another example.

Man has flat on rocky road. No one’s jack fits under his 4X. Man and crew spend 45 minutes digging rock to get the jack under the suspension. Finally, success!

Coyote thinking dictates there is always an alternative. I’ve done it a hundred times. Find an appropriate rock and place it just in front or back of the flat tire. As small as double-fist-size will do. Now, drive up on it. It won’t hurt the flat! You’re only going to move a foot or two! Actually, I pretty much make this a standard practice for all flats. It’s now easier to place the jack under the 4X and requires less jacking to get the flat completely off the ground!
