Low-Pressure Polyurethane Wheel - 16 1/2in. dia. x 7.9in.W, 42cm, Model# WZ1-42UC

So far they have worked without fail. These tires make it so easy for my 15 year old daughter to bring her JY15 down to the water. ...about 40 meters all by herself...no struggle. Bringing it back up the sand....takes just 2 because of the weight of the boat. Tires are like the Hobie tires...huge displacement of weight that rides the surface of the sand.

The $116-$150 price for this wheel is outrageous considering the incredibly poor quality. Let's start with the 42cm polyurethane donut they call a tire. The "Heavy Duty" designation is highly questionable, because the material is very thin and easily punctured. The warranty is good for 6 months. How many times are you going to use your beach cart in six months? The recommended pressure is 2-4 psi, any more pressure and your warranty is void. The weight rating is 176lbs. Oh, and Wheeleez never seems to stock just the $86 WZ3-42U-T replacement donut.So I filled up my six tires (good for over a thousand pounds?) to 3 psi, according to my Wheeleez pressure gauge, then I loaded my cart with 500lbs of cooler, ice and beverages. By noon it was 95 degrees and my tires now measured 5 psi. So it is impossible to keep within the recommended tire pressures. There is no way that these tires support 176lbs each at less than 4psi. At that pressure and weight the valve stems are riding on the ground.The bearings are the weirdest two piece plastic units I have ever seen. They are split vertically right through the ball races and then melted together. But that is ok because the bearings roll so badly they feel like the balls are rolling in sand before you even get on the beach. The felt seal are a joke. The split plastic wheel hubs are so warped it is hard bolt the parts together. Literally the best parts on the entire wheel are the stainless bolts and nuts, which I had to replace because I am using the wheels as drive wheels on a live axle. So I voided the warranty on half my wheels before I even used them.So if I hate these wheels so much why did I use them on my awesome Little Giant 3' wide x 7' long motorized beach cart? Because these are the only sand tires you will find on the internet that are not smaller than 10" or bigger than 21" in diameter. Trust me, I looked at tires for everything from golf carts, lawn mowers, midget racers, go karts, bar stool racers and even Australian desert kite racers and could find nothing for sand in the 12" to 19" diameter range. If you find something, let me know!But they do indeed work excellent on sand, just avoid anything sharp... like shells, fish hooks and plants.

I have been using this particular Wheeleez product for more than 3 years and it has worked flawlessly. There is no more durable sand tire on the market. The Chinese Knock-Off’s are so weak you can pierce them with your finger on a 100 degree day.

Great so far

Used these for a beach wheel chair. They do not do well in the surf. After a few uses the bearings are full of sand and will not turn.

Similar experience with one of their beach cart conversion kits. One tire went flat in two seasons. No way to repair the tire. Has multiple leaks. Great while they work but expensive and low quality.
