10x3.00-4 Flat Free Tire, 10" Heavy Duty Replacement Tire and Wheel Assemblies, 5/8" Axle Bore Hole, Compatible Cosco Hand Trucks and Trolley Carts, 2.2" Offset Hub, 2-Pcs

They are well built and will be trouble free!

So far just knowing that it's solid rubber and 0% chance of a flat, I'm it's worth it and I think I could expect l at least 10 years lonevety. The price is right and super easy to just pop old tires of a 6 ft steel dolly. It's the best of all Dolly's and these make the no flat tire situation a definite and stars and we'll spent. $$ . I believe you could also replace like a really good Old wagon you know but the tire is probably flat but these tires won't go flat and it would be kind of worth it too just a thought but anyways I don't have a picture but I can update this hopefully

Worked great as replacements for my hand truck.

Wheelbarrow, motor rack, hand truck, etc.

I bought these as a replacement for the pneumatic wheels on my dolly that were always going flat when I needed it. No more flat tires.

I replaced the pneumatic tires several times with new pneumatic tires but sooner or later, usually sooner, they went flat. Not these guys. I don't use my handtruck often but now it will always be ready to roll. I don't know about the "longevity" question because I haven't had these tires long. They work well with the extremely heavy loads I needed to move.

Great for yard wagons, etc., BUT-I made the mistake of leaving the garden cart loaded with dirt for several days and the tires got flat spots. The flat spots have since gone away. Don’t leave them sitting under a heavy load.

Mom is 83. She said, "Don't get me anything for Xmas!!! D@mn-it!!" So, I got her these to lighten the weight of her favorite hand truck. Pneumatic tires, always flat, heavy. I thought she'd be mad when she opened them, but she was giddy!
