Marathon Tires Flat-Free Tire on Steel Spoke Rim - 3/4in. Bore, 26 x 2.125in.

The wheels are great and worked for the chicshaw that we built. This does not come with a set of two wheels even though it says "tires" I'm in the description line. So you will need to order two if that's how many you need. We had already built the coop and we're having chickens delivered the day this arrived for the final piece and I had to order another wheel and wait another week to finish my chicshaw so I could move it around. A bit of a hassle but the wheels work as advertised.

Packaged horrible very weak wheels bed very easy no ot very happy with them used them because I had to get the job done going to upgrade at some point in the future

The bearing size was the wrong size for my use. bought another set and it worked o.k.
