Multi-Terrain Wheel Replacement - Yellow / Black hub x 1 Each

How long has Mighty Max Cart been around?

We designed our latest cart and built our molds in 2009, then started fine-tuning the carts with production in 2010 in Texas.

Is there a store where I can go and purchase a cart locally in my area?

We are sorry, we have sold thousands of carts all over the USA and Canada, but we are about 98% online only at this time. We are in some ACE Hardware Stores and Bering’s Hardware in the Houston, TX area. We will be in stores in 2018.  But, all of our carts come with a 2-Year Parts Warranty, and direct Toll-Free Customer Support.

What are the primary materials your carts are made of?

The main frames are made of HDPP (High Density Polypropylene), a very rugged and flexible plastic that will never rust, oxidize, or permanently bend out of shape.

Our wheels have HDPP wheel hubs with no bearings to go bad and solid rubber tires that will never deflate and will always turn, even after rolling through salt water.

Our telescoping handle slides to a half-length, then turns underneath the cart base to make a small compact size, and it too is made of 100% HDPP. All Cargo Walls, Fishing Pole Holders, and Removable Tubs are also made of 100% HDPP. 

Our hardware is unique as well, made of nylon and stainless steel for many years’ use without rusting or oxidizing.  Our steel axles are double coated with black oxide and last many years!  We have carts in Hawaii with the original hardware and axles after six years’ use.

How does the Mighty Max Cart work in deep soft sand?

Not Recommended for Deep Soft Loose Sand

Will these plastic carts warp or crack in hot and/or cold temperatures?

No, our cart frames are guaranteed for two years and, while they flex and bend under loads, they will then spring back to their original shape.  If you leave your tub inside a car, or leaning crookedly in a closet or outdoors, and it warps, simply place the tub on a flat surface in sunshine and it will rebound to its original shape.  Be sure to store your Mighty Max Cart empty, preferably hanging it on a wall for best keeping.

Note:  as with steel and aluminum, there are all kinds and qualities of plastic on the market.  We use a special blend with the HDPP which allows the carts to flex under load and then spring back to normal shape.  We have special rubber blends that we add to the HDPP, which is how we can offer a 2-Year Warranty.  We challenge you to find another all-purpose cart, caddy, and dolly on the market with a 2-Year Warranty, and our Direct “MADE IN USA” Customer Support.

What are the Mighty Max Cart weight capacities?

The Mighty Max Cart with our flat wheels can hold over 500 pounds on concrete and hard flooring. The wheels were designed to transport heavy loads on hard floors for use by exhibitors, movers, equipment haulers, etc. 

The Mighty Max Cart with our Amphibious All-Terrain and Weatherproof wheels can haul up to 350 pounds on hard floors.  On gravel, sand, and uneven pavement, we recommend a weight limit of 200 pounds.

How do I remove a wheel?

Our wheels are held on with a one-way licking end cap, which will assure the user that a wheel will never come off during normal operation.  But if the need arises to replace a wheel or change out the type of wheels, here is what you do:  Pop the plastic cap off the end cap with plyers or a flathead screw driver.  Then bend the remaining metal retaining disk on one side towards you away from the cart.  Then bend the opposite side of the disk also towards you and away from the cart. Then carefully pull the bent disc back and forth while pulling it off the axle. It will come off, but we made it difficult for a very good reason.

What is the maximum weight on the Mighty Max Cart on deep soft sand?

We do not recommend using the Mighty Max Cart in deep soft sand.  It does work well on packed sand, wet sand, gravel, and rocky and muddy terrain. Everything sinks in deep soft sand, even the human foot.

What are the weight limits for the Mighty Max Cart flatbed in closed and fully opened positions?

Mighty Max Cart with Flat Dolly Wheels:

Closed Position:

• 500 + pounds on concrete and solid hard floorings.
• 350 pounds on gravel, muddy and soft ground.

Fully Opened Position:

• 500 + Pounds on solid concrete and hard flooring with load spread out over front and rear axles.
• 250 pounds on soft terrain like mud, sand, gravel and dirt.

Why do my Mighty Max Cart All-Terrain wheels have small flat spots on them?

If you leave a heavy load on the cart and allow it to sit for days or weeks, your wheels may get some small flat spots on them when you roll it.  If this happens, please empty the cart, and turn it upside down in direct sunlight. The flat spots will pop out in a few hours.  Just like car tires, if a vehicle is left in storage or outside without use for weeks or months, they will get dry rotted and have to be replaced. 

We recommend that, for long periods of time, you store your Mighty Max Cart empty in a car trunk, or in a garage, storage area, or closet, or hang it on a wall.  Our wheels are truly great, but constant exposure to sunlight, salt air, or harsh weather, can cause them to crack over time.  We do offer replacement wheels.

Do I still get a Free Hitch if Buy Two or More Mighty Max Carts?

Yes, if you purchase any two of our carts at one time we will send you a FREE Hitch Assembly to connect both of your carts, or to connect a cart behind a riding mower or 4-Wheeler.
