Marathon 4.10/3.50-6" Flat Free, Hand Truck / All Purpose Utility Tire on Wheel, 3" Centered Hub, 3/4" Bearings

Perfect, good quality!

Like, many here I have one of the Generac larger generators. Since 2004 I have replaced the normal tires three times, or bought and returned other no-flat tires that just did not fit or work right. The generator lives in a shed and every few months when I would go to test start the generator I would find the tires flat, distorted (due to being flat), and partly dismounted. Getting them blown up again required a jack and tools to remove the tire from the axle, soaping up the bead of the tire and wheel to get it to seel, a tie-down strap to compress the tire so the tire bead would touch the wheel and an air compressor. This was messy and time-consuming. These tires fit perfectly, maintain the weight of the generator, are sized so it rolls as designed, and most critically are never flat. If you feel the price of two replacement tires is high, then I believe after a year of blowing them up every month you'll decide on getting these. You'll be glad you did.

This is an excellent heavy-duty tire for the Hand Truck and we moved some VERY HEAVY stuff with it.

These are great wheels if this is the size you need. They fit my trailer and got it back on the road in no time at all.

Very easy to install on my trailer mover. Only took about 10 min. Worked very well !

I, like other reviewers here own a large wheeled Generac 15KW Generator. The tubeless tires provided on this unit are totally useless for a device that sits unused most of the time. Every time I went to use it (after a hurricane here in SE Florida) The tires would be flat! So finally, after some research, I found these tires, & ordered them. Amazon, as usual had them at my house in about 24 hours. Installation took about 20 minutes (after borrowing a floor jack from my neighbor, (I couldn't find mine!). I should have gotten these tires three years ago! Eliminate flat tires on your wheeled devices! Get some of these solid tires!

These are not good! The bar rings went out after 1 month of use. Trying to see how to get a refund.

The tires in question are good. I picked them up for a GoKart build I am working on. These tires are slick. What do I mean by slick? A very hard tire but smooth. It's suppose to mimic a reap tire minus the tube. The tire itself doesn't actually mimic a real tire at all and I would be scared to put anything heavy on them if I am using these tires for a dolly. Why you might ask? Well if you are working on dirt it shouldn't be a problem but I feel if you work on cement it might not grip. If the tires are broken in meaning that shine wears off it should be fine. My other concern is weight. Weights the biggest issue I feel given these are rated for 300+ I buy two in theory it should be able to withstand 600 pounds correct? I feel these will snap under 300 from a one inch drop off a curb. I have bought simular tires before with rims like this and the problem on these tires are the welds. They put the tiniest weld on the center hub where the bearing go and expect it to withstand heavy loads. Read other reviews they will state the same. If you are looking for a good cheap dolly tire for light items this is a great option. If looking for a GoKart build or heavier weight keep looking.
