Enjoy this product it . It holds to the ground real well on the street and in gravel really like the 40 lb of air pressure you can put in.

I picked up this unicycle with training wheels toy at a thrift store for a couple bucks. It originally cost $250. It didn't have any tires on the back two wheels.Doing research for it, I found it had a hard to find tire size for the rear tires. Apparently lots of people were having issues with the original tires only lasting for a few weeks and trying to find replacements.I looked and found these on Amazon for about half the price that people were quoting for replacements.These are a lot nicer than the original ones from what I can see in pictures.They went right on nicely and have great tread on them. They are thick enough that they should last a while.So for around $30 this is ready to go at a fraction of the cost!My son will be very excited when he gets home and sees this ready to ride!

Very easy install, looks to be the same tread pattern as the original tires on an mx350 razor. I had no trouble mounting up these new tires, it was actually harder to take off the old tires than it was to mount these new ones. The rubber is very compliant. After mounting, filling up the tube with air was easy and seated the tire onto the wheel very easily. I only needed one of the tires (on the rear) but it was so easy I mounted the front ones too just to basically have new tires.
