What size wheel do Costco shopping carts use?
Costco Wholesale carts use a 5-inch polyurethane wheel with a 5/16 inch axle, rated for 250 lb load capacity per wheel — higher than a typical grocery cart because Costco shoppers buy in bulk. Tread width is 1-1/4 inches.
Are these OEM parts for Costco?
Yes. The Costco fleet wheel matches the standard P&H 250 lb-rated polyurethane line. Same compound, same dimensions, same load rating.
Can I get bulk pricing for my Costco group?
Yes. Costco regional or warehouse-level procurement teams get tier pricing automatically and can request EDI integration + NET-30. See the fleet program.
Operate a multi-store Costco fleet?
If you maintain carts across more than 5 Costco stores, you should be on our fleet program. Tier pricing (up to 15% off at 1000+ units, RFQ over 1500), dedicated rep, EDI, NET-30 terms, custom packaging.
More questions about cart wheel replacement.
Common questions from store-ops, facility managers, and procurement teams.
How fast does this ship?
Orders placed by 3:00 PM Central Time on a business day ship the same day from Mansfield, TX. Standard ground reaches most US destinations in 1 to 5 business days.
What if the wheel does not fit?
Every order ships with a 30-day fitment guarantee. If the wheel does not fit your cart, we will exchange it for the correct part and cover return shipping in the contiguous US.
How many wheels per cart should I order?
A standard shopping cart has 4 wheels. Most replacement orders cover all 4 to keep the cart rolling evenly. For a full fleet, plan for 4 wheels per cart and budget 10 to 15% extra for spares.
Do you offer NET-30?
Yes, after the second successful order. Submit a credit application via the RFQ form and we will respond within one business day with terms.
