I was looking for some of-road looking tires for a 1/25 scale kit-bashing project, but the only after-market tire sets I could find were either stock or racing tires. Then I stumbled on these, which are inexpensive, and have just the right look and size for what I'm doing. The tires are rubber, and the wheels are yellow plastic, and two metal axle rods are included. The wheels come disassembled, and so can easily be painted. The only drawback for my use is that the back of the wheel is open, and toy-like, but this can be hidden by painting it black.
