Here is my solution to the expensive wheel boots, I make my own, out of wood. You can custom size them, I use them on my mower and edger! I made a variation to hold crates, fuel cans ect. For example the boot on the mower was made by recycling the plywood from my old truck box cover. I just attached a cut down 2x4 to the side of it, drilled holes and put bolts thru it (I found if the bolts are extended about 1 1/2 inches it works the best). Placed the boot where I wanted it and drilled thru the floor of the trailer. I went underneath and screwed a 2 x 4 to the floor to cover the holes, went back inside and redrilled the holes to the proper depth and inserted the custom made boot. I made these for crates and fuel containers. Only takes minutes to make and inexpensive and you can make them to any size you like.
