Wheel DiameterFront Drive Wheel: 10 inches (approximately 25.4 cm) in diameter. The larger sizing allows toddlers to achieve maximum forward momentum with minimal effort per pedal rotation.Rear Support Wheels: 8 inches (approximately 20.3 cm) in diameter. These shorter, wider wheels create a low center of gravity to actively prevent the trike from tipping sideways during sharp turns.Tire Profile & ConstructionMaterial Composition: Engineered from heavy-duty EVA foam polymer (Ethylene-Vinyl Acetate), which provides a puncture-proof, flat-free riding experience that entirely eliminates the need for air inflation.Tread Design: Molded with a deep, slip-resistant grooved tread pattern that offers smooth traction across indoor tile, outdoor concrete pavements, or manicured lawns.
