It fits widely used 11x4.00-5 size applications and includes spacers and bushings so you can adapt the hub to your mower without special tools. Designed to resist punctures, provide stable load capacity and preserve operator comfort, the RUTU assembly aims to reduce downtime and eliminate the nuisance of flat tires.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this assembly prevent flats while still cushioning the ride?\u003c\/h3\u003e\n\n\u003cp\u003eThe RUTU tire uses a solid polyurethane core engineered to behave like a foam-filled tire: it won’t puncture or lose pressure yet still flexes enough to absorb bumps. The material choice preserves a pneumatic-like feel without air, so you get consistent traction and cushioned operation across typical lawn and garden terrain.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eSolid military-grade polyurethane core resists punctures and cuts.\u003c\/li\u003e\n  \u003cli\u003eRubber outer tread for grip and non-marking contact.\u003c\/li\u003e\n  \u003cli\u003eCushioning engineered to mimic pneumatic ride without air pressure maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this wheel fit my zero-turn mower and other equipment?\u003c\/h3\u003e\n\n\u003cp\u003eThe assembly is sized as an 11x4.00-5 and comes with an adjustable center hub and multiple bushings to match most common caster hubs.
