You guys told me I had to have a set of PR Bushwheels tundra tires for the 1/3 scale World Models Super Cub I've been building so I went ahead and ordered a pair. They weren't on the plane for more than a couple of days and I went to put air in them and pushed the air fitting into the tire. big time The guys at PR Bushwheels said to fish the fitting out with a pair of needlenose pliers but I ended up doing what I've shown it the video below. Nice product, by the way, and a nice bunch of people up there in Alaska where they're made. Here is the video I referred to where the guys at PR show how to make a pump for your tires.
