Marathon10" Swivel Caster with Flat Free Tire

I purchased these wheels to replace the wheels on my John Deere MC519 Cart as the wheels at John Deere were super expensive. The casters lined up to the cart perfectly and bolted right on. The benefit of these wheels is that they are solid and do not require constant filling of air, they also have a grease fitting so you can keep them rolling easily. Currently I have towed the cart around for the day and there has been no issues, I will update if anything changes.

Wheels were put on a deer blind conversion to chicken coop works great the the ex deer blint was 5 foot by 10. Hook up to mule and moved about..

excellent caster wheel for the money, pretty heavy duty, rolls smooth , turns easy, has grease zirc for grease into the caster bearing, does a great job for the big heavy yard cart I made. This wheel is 10 inch diameter with a total height of 12 inches with no flats to worry about as well.

This is a Quality product.

Living in the Ca. deserts & in a wheelchair I needed something more beefy than a standard chair comes with. After locating Big (12.5 x 4.5" drive wheels and tires these fit the build for the rear casters. Seem to be very solid & flat free is a big plus for this wheel

I have several carts with these wheels I have Had only one fail. Great wheels for the money.

I installed two of these swivel casters on the back of a manure spreader. After a week, they would not swivel because the bracket was hitting the bolts that attach it to the spreader. Now I have to kick the tires to get them pointed in the right direction. They do have grease fittings on the axle and the swivel bracket. And I made sure they both had grease. I like the thought of having a tire that won't go flat, but I need one that lasts more than a week.

This has turned out to be a disappointment, for a fairly heavy load but for a use case on a smooth concrete floor. The bottom line is that I think the capabilities of this wheel, the load rating in particular, have been a bit overstated.(As an aside -- I should have noted the sketchy, inconsistent product images and moved on instead of purchasing these. Out of 5 images in this listing as I'm writing this, only 2 are of the actual product being sold. Image 2 is of a solid rubber or pneumatic tire (not the foam tire in the real product, notice the difference in the metal wheel size), and 4 and 5 are of totally different casters, not even the same size. A 10-inch caster on a furniture dolly? Really?)I ordered four of these for a lumber cart, and what I got was a set of reasonably sturdy casters with what seem to be decent bearings and grease fittings. After attaching them though, what I ended up with was a cart that could not be moved, because the wheels would not swivel. Nothing wrong with the bearings -- the problem was the contact between the tires and the floor.Under about ~250lbs each the tires' contact patches were so large that the force required to swivel them was beyond what could be applied to the cart in a controlled way. The cart was basically locked in position because the wheels couldn't steer. And I found when I removed them that the tires had a flat spot that did not rebound, so rolling the cart would likely have been difficult if I'd been able to do that.300 pounds may be a good rating for the functional metal parts of these casters, but it seems to be beyond what the tire material can handle.
