Machined aluminum ball bearing wheels with rubber tires: Traxxas now offers an impressive set of red and blue anodized, machined aluminum wheels with rubber tires. The precision 6061-T6 aluminum wheels feature a stunning anodized finish and run on rubber-sealed 5x8mm ball bearings. For controllable and seemingly endless wheelies, Traxxas has developed a durable, soft rubber compound tire that reduces lateral movement for stable, consistent wheelies. The rubber tires are sold separately and can also be mounted on the standard nylon wheels.
