Which wheel fits a Costco shopping cart?

Costco Wholesale fleet carts use a 5-inch polyurethane wheel with a 5/16 inch axle, rated for 250 lb load capacity per wheel. Costco carts are oversized and load-rated higher than a typical grocery cart because shoppers buy in bulk pack sizes. The standard P&H 5-inch polyurethane wheel fits the Costco cart frame and matches the factory load rating. Tread width is 1-1/4 inches with dual precision ball bearings.
