Alpha #4238 Piranha Race Tires 3/32x13/16 Small Hub (0.400 dia), Full Width Hub. The small hub has no boss area for the setscrew. (The hub is the same diameter along the entire width of the wheel.) The rubber is glued all the way to the edge of the rim. A great short track tire. These tires should work best on flat, short, or tight tracks. "Soft, Natural, Aromatic Rubber." Alpha's Piranha tires really bite the track, especially when very clean and/or slippery. And they feature high quality, lightweight magnesium rims. These rims give the Piranha tires a big advantage over the other brands using aluminum hubs. The original Piranhas have won thousands of races! Features a cup point set screw.
