The Jeep scissor jack should be fine for changing a tire on the side of the road. It is easier to use and safer than a bottle jack when used on flat ground.
I’ll use it for various work underneath my Jeep where I need to work on suspension off the ground. In some cases it’ll be easier to raise the frame high enough for jack stands to let the suspension to droop by using a bottle jack than using the super heavy floor jack that I have. That thing is a monster.I use the 6 ton. When placed under the axle there’s enough length to raise enough to change tire. Unless you plan to use it for something else besides changing a tire .
