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.

Installed easy and value for the money. Definitely worth it.

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.

Everything was great until I rolled the box on the wheels and I noticed a thud every revolution of one of the wheels. After closer look I saw the flat spot in the wheel. So this is useless as a smoothly rolling box. This may be a one off abnormality but it's something to wary of. I'll have to return the set and perhaps look for a Pneumatic tire at least it won't be flat at the start.
