Bushwheels are STC'd.
I know how to research STC's on the website. What I want to find is the tire sizes approved by cessna for the 150. An stc is not needed if something is already approved by the manufacturer. For example, 600 700 & 800 MLG tires (4 ply) are all approved for the C-170 on the TCDS-- therefore an STC or any other special approval is not needed. The C-150 TCDS does not list any tire sizes, and alot of things the 170 TCDS sheet lists are not included either. I repeat, where are the approved tire sizes for the C-150 listed? It may be that Cessna's Illustrated Parts catalog is the final word on approved parts for the 150. There is no 150-D specific "shop manual", it is covered in the series 100 manual.
500-5 for the nose for all.
