It's okay, it breaks easily if not be careful will break easily,  if carry accident to hit some where else will break in the corner.
I broken 4 , I have to buy again, I don't have no choice. If you put it in the car to don't support will be break because it will slide in the car and break .

The tire has a nice soft wall but you might want to add a few more pounds of hair when compare to others with stiffer compound.

I bought this product despite the reviews that said it would fall of my wall, because I figured I was clever enough to make that not happen. With judicious application of glue, this turned out to be completely correct. However, despite the fact that for 3 months it has very stably hung on the wall ( and it has been bumped and jostled quite a bit in that time), and it shows no sign of weakening and falling, I do have a durability complaint. The glass is extremely, extremely fragile. It barely takes a bump or jostle to crack it. Mind you, the cracks aren't large, or even all that noticeable to someone who isn't looking closely. But I notice them. Still, I bought this as a stop-gap until the time I could afford real framing. That time is ever nearer, so I'm not completely unhappy with my purchase.

its a nice tire but very very soft ... the walls are seriously thin. i ripped a set in less than 300 miles on them.
gator hardshelll is the best.

I've had these on my wall for about 2 years now, finally going to replace them. As others have mentioned the plastic is very light weight and I am always concerned everything is going to come crashing down.... And with a slight accidental nudge of a tool you can watch everything come crashing to the floor. (only to curse yourself for still having these in your garage.)

I purchased a set of 4 Falken Wildpeaks 275 70 r18 on June 5, 2018 from amazon in anticipation of preparing for a long road trip pulling a 22 feet travel trailer from California to Yellowstone NP.  On the way home west on the 70 interstate just west of Rifle, Co., I experienced a blowout of the front driver side tire going approx 60 mph.  The tires only had approx. 3000 miles on them.  I managed to pull onto the right shoulder and discovered that the tire a blown out the side wall in numerous places.  I have attached pics.  You can see that tire is still brand new with deep treads remaining.  I don't know how many other people have experienced this with these tires but it was one of the most scary experience I have felt behind the wheel.  I had AAA put on my spare and I drove to the nearest tire store (45 miles)and replaced all 4 since I did not trust these tires anymore.  I do not recommend these tires a would like to get a refund..

Looks good but our tire exploded after being pumped up. It ripped the tire as well.

Pumped up the tire, the kids sat on them on a smooth garage floor (holding on to the wall) for a few minutes while it rained that night.

A couple of hours later as we drove home with the unicycle laying in the "wayback" (cargo area) of our CUV the tire exploded. Sounded like a gun shot.

Now tasked with finding a tire and tube to fit this unicycle and 18" seems to be a non-standard size for the local big box retailers.

Do buy this if it is going to be used in a vehicle/truck with any amount of vibration.
The long arm bounces way to much and the metal arm in the rubber sleeve will break.

Put a pair on my light truck and they have performed well and have very little wear over three years.  However, I was turning in my drive way and a front tire hit a blunt 2 inch diameter branch which went right through it.  Looking at the sidewalls now that the tire is trash they look to be about 5 mm in thickness.  Not very sturdily made at all.  These tires are probably fine for most people, just don't hit any curbs!

my grandson loves to play with the car, but it is more fragile than more expensive cars. He just has to be more careful.

The pieces that attach to the wall are very sturdy and heavy. The bars however are very flimsy and light. I am worried about how much weight they can hold once we put a couple wet towels on them. I will update my review after some use.

The solid tires on this cart seemed like a good idea because they will never go flat  However, on uneven ground, such as a lawn, it's hard to push/pull the cart because the tires are too stiff. Pneumatic tires are much nicer for this type of terrain. The cart is easy to push/pull on a solid surface.  Also, a minor annoyance is the wheels sit a little proud of the cart. I'm constantly catching the wheel on the garage door, post, tree, or any other obstacle.  It would have been a better design to have the wheels sit flush with the cart edge.

The cart body is a nice size and shape. No complaints there.

High end tires and I rode easy and on bare pavement at first(as suggested).  Still lost a lot of studs on front tire.  Not very pleased with that.

This product is potentially dangerous for some bike tires. It has already punched into my rear tire twice, and I have just had it for less than a month. The extended hole that houses the kids handle bars point directly to the top of the rear tire of the adult bike. Any slightly uneven spot in the road. such as speed ramps, protruding sidewalks, etc. causes the kids hitched bike to drop a little and that is enough for the little extended portion of the handle bar hole to hit the rear tire of the adult bike in a very dangerous way. I am going to advocate a recall
