The Landes fork comes with an STC which approves the airplane (182/206, etc) with 8.50 x 6.00 tires on all three corners. The stc does NOT permit a smaller nosegear tire, such as the 8.00 x 6.00.
I've run a 206 with the Landes fork, and 8.50's on all three, and I can't recommend it. The airplane sits at too high an AOA on the ground, and it's really easy to land nose first or all three at once. I put an 8.00 x 6.00 nose tire on, based on a field approval, and that was a great setup. We ran three 206s that way, and they worked fine.
DO NOT overinflate your nose strut. That strut is there to absorb landing and takeoff loads. The hot ticket is to get a piece of stout rubber hose about the diameter of the nose strut, split it lengthwise, and hose clamp it onto the bottom of the shock strut. The length of hose needs to be about 3 inches. Then inflate the nose strut to the recommended pressure. This piece of hose will prevent the strut from bottoming out, which is hard on everything, and at worst, will bang up that piece of hose, which is easily replaced.
We did this as a minor alteration, and this is a very common practice in Alaska. In fact, to see one of these aircraft WITHOUT this up there is really unusual.
Also, if you are going to the bigger tires, consider attaching a tail spring off a CUb or..... to the underside of the tail just ahead of the tail cone to prevent dragging the tail. Just use the main leaf of the spring.
