✅ Approved Applications — What This Wheel Is FOR
🚫 FORBIDDEN APPLICATIONS — DO NOT USE ON
❌ HIGHWAY USE — Not rated for road speeds. Will fail under continuous high-speed rotation.
❌ MOWER MACHINES — Lawn mowers, ride-on mowers, zero-turn mowers. Not designed for mower deck or drive applications.
❌ TRAILERS — Boat trailers, box trailers, camper trailers, car trailers. Cannot support sustained towing loads.
❌ MILLER MACHINES — Heavy milling equipment, industrial machinery. Will fail under heavy industrial use.
❌ ANY HEAVY MACHINERY — Excavators, loaders, agricultural equipment, heavy industrial carts.
⚠️ CRITICAL WARNING — PROLONGED HEAVY LOAD WILL FLATTEN TYRE ⚠️
This is an OFFSET HUB / SINGLE HUB wheel. The offset design creates uneven load distribution when used on heavy or high-speed applications. DO NOT use on any machine that runs continuously for extended periods.
Product Description — 13x4 Pneumatic Wheel (Offset Hub)
This 13x4 4.00-6 Pneumatic Wheel features an OFFSET HUB (SINGLE HUB) design. The wheel is specifically manufactured for light-duty applications including wheelbarrows, hand trolleys, and garden trolleys. The pneumatic (air-filled) tyre provides a cushioned, comfortable ride over rough terrain and is puncture repairable — easy to patch if you get a flat.
The wheel has a 16mm/20mm bore with ball bearings for smooth rolling. The rim is constructed from durable blue-painted metal. Net weight is approximately 2.2kg per wheel (lighter than solid version).
⚠️ IMPORTANT — THIS IS AN OFFSET HUB WHEEL: Unlike centre hub wheels, the offset/single hub design means this wheel is NOT suitable for highway use, mower machines, trailers, miller machines, or any heavy machinery. Prolonged heavy load will cause the tyre to flatten. Use only on manual push/pull equipment like wheelbarrows and hand trolleys.

⚠️ Understanding Offset Hub (Single Hub) Design — Why Application Matters
What is an Offset Hub / Single Hub? Unlike a centre hub wheel where the axle passes through the middle of the wheel, an offset hub (single hub) has the mounting point offset to one side. This design is common on wheelbarrows and hand trolleys where the wheel mounts to a single arm or fork from one side only.
Why can't this be used on mowers, trailers, or highway? The offset hub design creates uneven force distribution. Under sustained heavy loads, high speeds, or continuous operation (like a trailer or mower), the offset hub puts excessive stress on one side of the tyre. This causes the tyre to deform and flatten over time.
Pneumatic vs Solid — Which should I choose? Pneumatic tyres offer a smoother, cushioned ride and are repairable if punctured. Solid (foam-filled) tyres are 100% puncture proof but provide a firmer ride. Both have the SAME offset hub design and SAME usage restrictions.
⚠️ PROLONGED HEAVY LOAD = FLAT TYRE: Even on approved applications (wheelbarrows, hand trolleys), leaving a heavy load sitting on this wheel for days/weeks will cause the tyre to flatten. Always unload equipment when not in use.
🔧 REAL WORLD USE CASE 🔧
✅ CORRECT USE — Garden Wheelbarrow: Homeowner using for soil and mulch. Pneumatic tyre provides smooth roll over lawn. Maintained correct air pressure. No issues after 18 months.
❌ INCORRECT USE — Trailer: Customer attempted to use on small boat trailer. After 30 minutes of towing at 60km/h, tyre developed flat spot and sidewall failure. NOT covered under warranty for incorrect application.
"The air tyre is so much smoother on my bumpy driveway than the old solid wheel. Just remember to check pressure!" — Customer feedback
