This is IMEX's famous K-Rock tire mounted on one of our most popular rims, the Pluto. The Pluto rim is a true beadlock rim on both front and rear and is available in a multiple array of combinations of colors. The rims are 24mm hex hubs, but come with a 18mm square adapter for other large scale trucks such as FS Racing, FG, etc. These are heavy duty tires and will handle tons of abuse.
