Pneumatic tires do not hold up on extra weight on a truck cart; a tube is necessary & that's why I ordered two.

Product has several weakness in design. Tires should be significantly larger and stick out well past width of unit. This would allow for much greater stability. I sort of anticipated that. Also the design is weak as far as how to fill containers from it. I will use it to mix liquid applied fertilizers and other products that improve growth. I will make the modifications on my unit to make it more useful.

Does NOT hold up to brushless, 2S LIPO power and oversized wheels.  I've gone through a set about every two to three packs.  May hold up to normal SCT tires, but definitely not 2.8 Trenchers.

They do not take much pressure.  One of them cracked the first time I used it.  Granted that it had pressure on it from the rear tire, but I have others that held with the same amount of pressure.

Tire went on okay. I had a Universal brand utility wagon with a pneumatic tire that leaked. This went In okay (used a cheap set of turs irons) and has been working for about six weeks already. Size was correct. No directions on pressure rating though. Used 30 psi, if I recall.

The item was easy to assemble and appears to be sturdy.  The major issue is that one tire showed up flat and the valve stem was separated from the tube.  Will have to buy another tire unless the supplier can replace it.

I have changed these tubes often due to debonding of the rubber joins not punctures. I would not recomend this  product.

Package arrived on time and in good shape.
Took about an hour to assemble - the instructions are clear.

One of the tires was flat. I filled it with air 3 times, and it loses pressure within an hour.
I wouldn't recommend this product.

After 2 years the right tire would not hold air. I noticed cracked surface and some peeling of the rubber. When I did a soap and water test itt showed multiple air leaks.
I thought oh well I'll just have the tube repaired. I took it to my mechanic and he showed me multiple spots inside the tire where the belt was exposed and actually puncturing the tube.
Bottom line? Cart ok. A bit lightweight. Rusting somewhat.
Tires?--- total junk.
Replacement? $44 bucks. Add that to your purchase price.
Not a good deal.
Rating- D-.

Solid tire is a great concept for loads up to 350 lb. Why ever deal with air pressure, tubes, or cracked tires/valves.  The wheel is also superior to the original, with a ball bearing instead of a rust prone bushing.
Overall a great value for the price, especially considering my old wheel was very rusted and an interior puncture risk for a tube.  Pneumatic tires should become obsolete for wheelbarrows... big improvement.

I have a Specialized hybrid with stock tires, and have been having repeated problems with flats on the rear tire from running over thorns. I purchased this tire in hopes of improving that situation.

However, I didn't notice until after I received it that the "700x37" (actually a 28 x 1 3/8 x 1 5/8) has a recommended pressure of 58 psi and a maximum of 70 psi. My stock 700x45 tires, puncture prone as they may be, have a maximum pressure of 85 psi.

The rolling resistance of this smaller, lower pressure tire would be higher than my current tires. I'm already slow enough, I don't need extra rolling resistance. I'll save up money to buy Specialized's higher pressure puncture-resistant tire.

I would send this tire back but shipping is $8 for an $18 return, and it's not worth the possibility of getting a tenner to go through the hassle and risk being out both the tire and the refund. If the bead gets bent on the way back to Niagara Cycle Works they won't give a refund or return the tire. I'll keep it as a spare and as a reminder to scrutinize the specifications before buying any more tires.

When new its a Good tire with plenty of grip. When slightly worn i have managed to get flats. Not sure if it is Coincidence or tire breaks down that fast.

I'm kinda disappointed in the tire machine, I changed my tires size 275/60r20 and it was difficult to mount.  The arm is too low, so anything wider will be hard to clear .
balancer worked good. .

Love the tread but the side walls blow out after 6 to 8 months use. I ride cyclecross and love the traction this tires give. The trade off is they are heavy and do not last long. This was my fourth pair, I thought the airepressure would extent the life but did not. Will have to find another tire for this muddy season.
Pro:
The best traction off-rode tire I have every ridden on
Con:
Heavy and slow
Side walls blowout at the ride regardless of air pressure
Life span 6-8 months (40 miles per week)

Buy them and race for two months then find something else.

I weigh 170 lbs and my body weight is not enough to compress this thing to inflate my tire to 80 psi. it just feels like an air suspension that i'm bouncing on at that point. If I actually want my tire to go to 80 psi, I have to literally bounce on the pump once I've compressed it with my body weight as far as it does.

Been running these tires for a few months now on an older atv. Supreme traction. No punctures or flats yet. At the recommended 4lbs they do ride incredibly stiff and rough, however, I believe that is a result of the bias ply construction. To fix this I simply air down until they are comfortable. If I had to do it again, I might have gone for the maxxis bighorn where you're paying for a much more comfortable ride.

So far so good on the tires, I have been putting a lot of weight on them and they are holding up.
