The method by which the World Race and AcceleRacers die-cast vehicle tires are manufactured. Using heat and pressure, two or more plastic pieces are permanently fused together.

Sometimes these wheels are refered to as 'Cold Molded', 'Comolded' or 'CoMo.'

Hot Wheels began using these tires on some vehicles in 2003. All World Race/AcceleRacers die cast vehicles have co-molded wheels with the exception of 'filler' cars (ones that came with other items such as hyperpods and race tracks).
