I don't mean to argue, but I think that the diagram you are refering to was only valid for roadwheels of early tigers. I believe that late tigers had less roadwheels. The early tiger had 48 wheels (not including drive and idlers), while the late had 32. I'm just bringing this up, because I wouldn't want you to make a mistake. Here are links to the pictures which support my idea
This is the roadwheel configuration of a late tiger

Notice how the roadwheels don't go up to the edge of the track (except when the transport tracks are present)

Compare this to the early tiger, whose wheels go up to the edge of the track, even with the wide tracks installed (compare the second picture from the bottom on the early tiger page, to the fifth picture from the top on the late tiger page)

Mark 1 tank site also show the difference between the sturmtiger roadwheel configuration, and the early configuration

I believe that the number of roadwheels was decreased in late models, in order to get rid of the need to take off roadwheels in order to put on transport tracks. Like I said, I mean no harm, I just don't want you to make a mistake with this. If you would like further detailed photos, I have a 1/35 late tiger without it's tracks, which I flipped, and took pictures of with a diagram from an early tiger next to it for comparison.
Good luck with your build,
Tom
