Decide
Decide if you will be using new or recap tires. I went with recaps as my experience with flight school aircraft is that the recaps last quite a bit longer than the new tires. The recaps are slightly larger, so if you cut you pants to fit the recaps, you can always use new. The converse is NOT true. If you cut the pants for a new tire, the recaps will be too tight. I used about a 5/8? gap around the tire to layout the pant cutout...
