About Product Overview

This Marathon replacement tire solves the one problem every wheelbarrow owner eventually faces: a flat that stops the job cold. Built with a solid polyurethane core instead of an air-filled tube, it never needs pumping and can't go flat on a nail, thorn, or sharp gravel. The 13.3 inch wheel is sized to fit wheelbarrows and yard carts taking a 3.50/2.50 x 8 tire, with a centered 5/8 inch axle hub for straightforward mounting.

The ribbed tread gives it grip across lawns, mulch beds, and job site dirt, and the 300 pound weight capacity covers everything from potted plants to bagged concrete. Because it's flat free by design, it's a smart swap for anyone tired of patching tubes or topping off air before every use - homeowners, landscapers, and anyone running a wheelbarrow hard and often.

  • Material: solid polyurethane, flat-free construction
  • Wheel diameter: 13.3 inches; rim diameter: 8 inches
  • Axle diameter: 5/8 inch, centered hub style
  • Tread type: ribbed for traction
  • Weight capacity: 300 pounds
  • Fits 3.50/2.50 x 8 wheelbarrow and yard cart applications

Price check

Go ahead. Check.

You're going to price-check us against Amazon, Home Depot, and Lowe's. Everybody does. Good — open all three tabs. We'll wait. Then look hard at what you're actually being handed over there.

On Amazon, start with these four questions before you click buy.

01

Who's actually selling it

The brand name is on the listing. A different company is in the seller field. Those aren't the same thing, and the second one is who you're buying from.

02

Whether the warranty survives

Most manufacturers only honor a warranty when the unit came through an authorized dealer. We're authorized for Marathon. A third-party marketplace seller usually isn't.

03

Where the box came from

Gray-market stock, returns repackaged as new, and outright fakes move through marketplaces constantly. It all looks identical in the photo. It stops looking identical when it fails.

04

Who you call when it breaks

Ours is a phone number with a person behind it who has held this product. M–F, 6 AM – 5 PM Pacific. (866) 469-8556

The big boxes don't care if your hardware store survives.

Amazon, Home Depot, and Lowe's are built to pull every hardware dollar out of your town. When the local shop can't keep the lights on, the counter where somebody actually knew which part you needed goes with it. We're built the other way: real brands so you're never stuck on a marketplace, and a straight answer to buy it down the street when that's the better call. Support independent hardware — it doesn't restock itself.

Why we tell you to shop local

Shop Local · Support Independent

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
