Tamiya Small Dia. Semi-Pneumatic Tires w/Wheels(15239)

A wheel-and-tire set combining 3-spoke small-diameter wheels with semi-pneumatic tires, which flex slightly to absorb impacts such as jump landings, giving the car a basic form of suspension. The wheels are molded in a bright fluorescent green with "TAMIYA RACING MINI 4WD" lettering formed into the rims. Some car bodies may require trimming to clear the tires once fitted.

• 3-spoke small-diameter wheels, fluorescent green
• Semi-pneumatic tires (impact-absorbing)
• Body modification may be required on some kits

Fitment is close to universal — Tamiya lists compatibility across essentially its full chassis lineup, from the Type 3 through Super TZ-X and AR-family cars, since the tires mount on the standard axle hub. That makes the semi-pneumatic construction here a genuine alternative choice to the Reston sponge-tire wheel sets Tamiya also sells (No.219): sponge tires grip through a soft, tacky compound, while these trade some of that outright grip for the impact absorption of a slightly flexible tire body, useful on courses with jump sections rather than pure high-speed ovals.
