LTNICER 13-inch (4.00-6) Solid Flat-Free Wheelbarrow Wheels, 2-Pack — 320 lb Load, PU Foam

LTNICER 4.00-6 is a pair of 13-inch solid, flat-free wheelbarrow wheels built from high-density polyurethane on steel rims, designed to replace pneumatic tires and resist punctures for heavy-duty garden and utility use.

These LTNICER 4.00-6 flat-free tires are a one-piece, tubeless design combining a rugged steel rim with high-density PU foam for longer wear and puncture resistance compared with traditional rubber pneumatic tires. Each wheel measures approximately 13.31" in overall diameter with a 3.58" tread width and fits a 6" rim diameter, offering a reliable alternative for wheelbarrows, wagons, garden carts, and light utility trailers. The wheels include bushings and nylon sleeves so you can adapt a centered hub starting at 1.75" and extend as needed to match axles up to 5.75".

How do these flat-free wheels improve everyday yard work?

Because these tires are solid and tubeless, they eliminate the downtime and maintenance associated with flats, punctures, and air pressure checks. Their dense PU construction resists cuts and abrasion found on gravel or thorny terrain, helping you finish tasks faster and with fewer interruptions.

• Solid PU foam resists punctures and seals out leaks.
• One-piece tubeless build removes need for inner tubes.
• Works on gravel, soil, and rough surfaces without frequent stops.
• Offers consistent rolling feel under load for predictable handling.

What are the exact measurements and load limits I should care about?

Each wheel has a nominal tire diameter of 13.31" and a tread width of about 3.58", fitted to a 6" rim. The axle bore measures 5/8" (0.629") and the center hub starts at 1.75"; included spacers let you extend the effective hub length as required. These wheels support up to a 320 lb dynamic load when installed properly.

• Overall diameter: approximately 13.31".
• Tread width: ~3.58"; rim diameter: 6".
• Axle bore: 5/8" (0.629"); centered hub adjustable from 1.75" to 5.75".
• Dynamic load rating around 320 pounds per wheel under normal use.

Will these wheels fit my wheelbarrow, wagon, or cart?

They are compatible with many wheelbarrows, garden carts, generators, and utility platforms that use a 6" rim and a 5/8" axle bore. The package contains two sizes of bushings and multiple nylon sleeves so you can tailor hub width and bearing fit to your axle system; double-check your axle diameter and available hub length before installation.

• Includes 2 flat-free tires (2 pack) and assorted bushings/sleeves for fitment.
• Works with standard 5/8" axles; 3/4" bushings included for larger shafts.
• Adjustable hub length helps align with common cart frames up to 5.75".
• Recommended to measure axle and clearance prior to ordering.

How long will these solid PU wheels last compared to pneumatic tires?

LTNICER uses high-density polyurethane that typically endures several times longer than pneumatic rubber tires under similar loads because it resists cuts, sidewall failures, and blowouts. However, avoid leaving heavy loads stationary on the tires for prolonged periods to prevent compression set and preserve long-term performance.

• High-density PU offers enhanced abrasion and impact resistance.
• No tubes means no flats or patching in the field.
• Durability depends on load, terrain, and storage practices.
• Avoid long-term static loading with heavy weight to reduce deformation.

Who is this for? These LTNICER 4.00-6 wheels are made for homeowners, landscapers, small-farm operators, and contractors who want low-maintenance, puncture-resistant replacement wheels for wheelbarrows, garden wagons, trolleys, and light utility equipment. If you need a dependable, tubeless 13" wheel that tolerates rough ground and reduces downtime, this two-pack with adjustable hub components offers a practical, long-lasting option. Confirm axle diameter, hub clearance and tire size before purchase to ensure a correct fit.
