Its quite easy, and cheap/free if you already have a tape measure or 2 yard sticks
Maybe easy for you, but I have a hell of a time trying to hold all of that together and measure for clearance at the same time.
The thing that concerns me about the "Wheelrite" is that the actual tire simulation doesn't seem like it would be very accurate. I mean when they give a section width, where is that measured? Is it at the widest part of the sidewall? How could you bend a piece of wire in the shape of the outline of the tire and have the correct section width and tread width if you don't know where the section width is measured? Did that make any sense?
Maybe I'll just make my own jig. Maybe I will call Percy's and get their take on the deal.

you need to hold a straight edge on the rotor/drum face, and measure back with a tape measure. Not rocket science. It will give you a good idea of what kind of clearance you have in the wheel well and you can figure out a tire/rim combo from that.
The tool you are showing will allow you to figure of the height of the tire, but i dont think it will work well with a large tire with a lot for sidewall and bulge, like a slick or drag radial on a 15" rim, its more for low profile tires or larger rims where there is not a lot of bulge.
Yeah when Percys first had the wheel rite at PRI (some years ago) it was a billet aluminum piece. I looked at it and decided when they came out with it I was going to buy one. Well after I saw it in a magaazine I orderd one cause it was only $60. But it is a flimsy piece of plastic not worth the $60 I spent on it.
Best thing I hve found for measuring wheels is have a spare wheel you know all the dimensions for. Use it for mock up then either do the math on paper or find an online wheel offset calculator and punch in the dimensions of the wheel you have. Then play with the width/offset of new wheels and the calculator will tell you how much the inner and outer lips move, transfer that to the mock up wheel and see if anything hits.
