MaxAuto 11x4.00-5 Lawn Mower Wheel Assembly — 3.4" Centered Hub, 3/4" Bushing, Solid Polyurethane

MaxAuto 11x4.00-5 lawn mower tire on wheel is a pre-assembled, flat-free replacement wheel with a 3.4" centered hub and 3/4" bushing, supplied with an adapter kit to expand fitment options.

This ready-to-fit wheel assembly pairs an 11" diameter, 4" wide smooth polyurethane tire with a 6" rim and a centered hub, designed as a low-maintenance replacement for many zero-turn mowers and garden tractors. The tire is solid—no air required—so it eliminates flats and frequent pressure checks. The included adapter kit (additional bushings, spacers, and washers) lets you change hub length and bushing diameter to match a wider range of machines.

How will this flat-free wheel simplify mower upkeep?

Because the tire is made from solid polyurethane foam, you won’t deal with punctures, slow leaks, or seasonal pressure changes. That reduces downtime and the need for patching or inflating. The maintenance savings are most notable for frequently used mowers or grounds equipment kept outdoors.

• Puncture-proof solid polyurethane tire — no tubes or air needed
• Pre-mounted on a 6" rim for simple bolt-on replacement
• Adapter kit included to reduce compatibility work
• Load rating up to 350 lbs (158 kg) per wheel for typical lawn use

Which machines will these 11x4.00-5 wheels fit?

The wheel assembly fits many front caster or small rear positions on zero-turn mowers and compact garden tractors, but compatibility depends on hub length and bushing size. It’s commonly used on models like F935, RTZ42, ZTX42, Z325, Z355R and similar machines. Check your existing tire size, hub length, and bushing diameter before ordering.

• Tire size: 11x4.00-5, rim diameter: 6"
• Hub length options available: 3.4" centered hub (other lengths adjustable with adapters)
• Bushing sizes: supplied 3/4" bushing plus extra 5/8" bushings in kit
• Not compatible with certain models like RZT L, Z335 E, Compact Pro 34

How do the adapter kit components expand compatibility?

The adapter kit includes multiple bushings, spacers, and washers so you can alter the effective hub length and bore diameter without machining or specialty tools. Swap in different bushings or add spacers to match the spindle and secure the wheel properly. This makes the wheel usable across several axle and hub setups.

• Includes four 5/8" bushings and other spacers for bore adjustment
• Four 1/4" and 1/2" spacers for hub length tuning
• Washers provided to ensure correct preload and fit
• All parts allow fast field adjustments for many mower spindles

What performance and care notes should I expect?

The smooth tread polyurethane tire offers predictable rolling and reduced maintenance, but it’s not designed for sustained static loads or highway speeds. Long-term stationary loading can create flat spots on solid tires, and the assembly is rated for typical lawn equipment use only. Follow basic installation checks to keep the wheel secure and aligned.

• Maximum static load per wheel: 350 lbs (158 kg)
• Not intended for highway use or prolonged static weight bearing
• Solid tire resists punctures but can develop flat spots if left under heavy load
• Inspect mounting hardware and adapters at first use and periodically

Who is this for: This MaxAuto 11x4.00-5 flat-free tire on wheel is aimed at homeowners, landscapers, and maintenance crews who want a low-maintenance, puncture-resistant replacement wheel for compatible zero-turn mowers and compact tractors. Choose this assembly if you prefer to avoid tube repairs and reduce routine checks, but be sure to verify your mower’s hub length and spindle bushing size against the included kit before purchasing.
