The Everbilt Gate Wheel will not function properly in this installation method. The mount is a fixed mount.
Yes it should, but it may not be a smooth movement because of the surface. But it will keep it off the ground without a problem.
The wheel is 1inch. However to accommodate smooth movement over uneven surfaces there is approx 1/2inch play between wheel and mount. You'll need at least 1.75inch between gate vertical tube and gate post.
Two shims are included that will work for that size gate tube.
It should be able to support about 200 pounds, the wheel is solid rubber. But remember the wheel is not very wide and should be rolling on cement or pavers. That amount of weight will push the wheel into the ground.
It will not bolt to a 4x4, but will easily bolt to a 2x4 or 2x6.
