NATIONAL STANDARD 4.80/4.00-8 Tire & Wheel Assembly — 16" OD, 2-Pack with 5/8" Bushings, 30 PSI

This 2-pack wheel kit arrives ready to install on utility equipment that accepts rims near 8.75" diameter, a 3" centered hub and 5/8" sintered iron bushings (3/4" bushing included). The tires are non-highway-service (NHS) tubed tires paired with robust inner tubes rated to 30 PSI, engineered to deliver the cushion and traction of air-filled tires while supporting payloads up to roughly 400 pounds per wheel. Because these wheels come pre-mounted on solid steel rims, most replacements require only a quick swap — but please double-check your current wheel measurements to ensure fitment.

Will these wheels fit my wheelbarrow or yard cart?

Measure your existing wheel or hub before ordering. This assembly fits tires with a 15.7" outer diameter and approximately 3.75" width, and expects a wheel rim near 8.75" diameter with a 3" centered hub and 5/8" bushings.

• Outer tire diameter: 15.7 inches (4.80/4.00-8)
• Tire width: ~3.75 inches
• Rim diameter compatibility: ~8.75 inches
• Hub center: ~3 inches; bearing/bushing: 5/8" (3/4" bushing included)

How strong and durable are these tubed tires for hauling?

These are air-filled NHS tires with beefy inner tubes intended for light to heavy-duty utility use. With a maximum tube pressure of 30 PSI and a load capacity around 400 pounds per wheel, they balance shock absorption and load support for demanding yard and jobsite tasks.

• Maximum tube pressure: 30 PSI
• Estimated load capacity: ≈400 lb per wheel
• Tire type: tubed, non-highway-service (NHS)
• Rim: solid steel, pre-mounted tire and tube

How easy is installation and what tools will I need?

These wheels ship pre-mounted on rims, so most installations are a straightforward axle swap. Depending on your equipment you may only need basic tools, but some makes and models require extra steps or hardware for secure mounting.

• Comes as a pre-mounted tire and steel rim (2-pack)
• Common tools: wrench or socket for axle nut removal/replacement
