Ar-Pro (2-Pack) 4.00-6" Tire And Wheel, 13" Pneumatic Tire, Extra Nylon Spacers Product Details 4.00-6? PNEUMATIC WHEEL ASSEMBLIES FOR RESIDENTIAL WHEELBARROWS - These tire and wheel assemblies are excellent replacements for wheelbarrows with 4.00? x 6? tire sizes. The most common types of wheelbarrows that use these tire sizes are 4cu ft wheelbarrows and regular residential wheelbarrows. 13? REPLACEMENT WHEELBARROW WHEELS - 13.2 inches is the actual outer diameter of the tire and wheel assemblies. They are not for highway use with a 2 ply rating and a maximum 300 lb load capacity. This makes the wheels highly suitable for heavy-duty hauling and garden work. RIBBED TIRE TREADS - Ribbed treads offer an advantage, especially for these tubed tires. They provide maximum traction and maneuverability in rough and uneven terrain, both in wet and dry conditions. The ribbed design also allows for superior water evacuation and even tread wear on hard, flat surfaces. WITH 5/8? BEARINGS - 5/8 inch is the standard for wheelbarrows, ensuring universal compatibility. To make the bearing more durable for heavy-duty use, each bearing is mounted on premium quality black steel. Please measure your existing wheel?s bearings to ensure compatibility. INCLUDES ADAPTER KIT - The adapter kit includes two sizes of plastic wheel spacers to adjust the 1.75-inch hub length to up to 4.75 inches. Includes 4 pieces of 1-1/2 inches plastic spacers.
