There is NO STC needed for the use of 8.5x6 tires on the C170. The FA Dodge info NMFLYR speaks of is a letter from the FAA confirming this. I had posted this info here on another thread. All that is needed now per the FAA doc is a 337 and the appropriate change to your WB and equp list. This applies to 170, 180, 182, and 185s.

If you are doing a 337 you are going to need some more paper work. I think you mean log book entry and up date W&B?

Some years back a friend gave me a pair of 8.50s to try on my '52 C-170B. I found them to be fine on dirt or grass, but they were a little squirrely on pavement.
I checked my allignment and it seemed to be OK and I tried a couple of different pressures and even installed double puck brakes. I finally gave them up since most of my flying was done on pavement. The 8.00s I tried came too close to the brake calipers without rotor spacers so I settled on 7.00s for regular use.
