Rock-N-RollerR-Trac 10" x 3" No-Flat Rear Wheel 2-Pack for R10, R11G, R12 & R18 Multi-Carts, Offset Hub

The Rock 'n Roller carts are the best option I've found to move equipment around. They collapse up small, don't weigh much, and are durable enough for moderate loads. I only gave it a four star rating because the original inflatable wheels had issues and I had to replace them. However, since I originally bought my cart they have replaced the inflatable wheels with a solid wheel design and that should solve the problem.

Loved how they resemble the original tires. New ones need the old tires inner bushings so make sure not to throw away the old tires.

Because prior to 2008, the axle diameter on these carts was 20 mm. Which means if you try to replace the wheels with whatever is shown here at Amazon, they are not going to fit!! You'd think this company would know that wheel replacements are much more likely to come from older carts, not newer ones. Can't these dumbbells even specify that? Can't AMAZON at least provide a little more technical specs. This is my third Amazon return in a week because of lousy (or none at all) specifications and descriptions.

I bought this entire handtruck thinking that it would help me in my business. But it doesn't!! It supposed to hold 500 pounds of weight but it doesn't. It's not supposed to get a flat but it did twice!!!! I thought that because it's compact and it says that it's built rugged that it can take a licken and keep on ticking. But it doesn't. For what I paid and how I use it it should be a strong peice of equipment. But it's not!!!
