This may seem crazy but it was the instructions and the simple tool supplied with the product that made this a great purchase. Yes, the product is high quality and the price was right but it was the extra got-your-back instructions that made this a brilliant purchase.
Working well so far. Very tight fit. Soaking in hot water first helps expand and soften slightly. A second pair of hands will greatly facilitate stretching it over the wheels. The only negative is that there was a slight "bump" and some flash (squeeze out material) at the seam. Prior to installing I stretched it over a round surface and used a 100 grit sanding block to remove this. Blades are tracking true and running quiet. My old orange tires became brittle and failed. Time will tell as to whether the new blue urethane is more durable.
You will find that the tire is stretched a lot! It was too wide for the wheel, then was actually a bit narrow after fully stretched. Given the crown of the wheel, it only touches in the middle 1/3 anyway. The tool along with at least one clamp are very necessary along with some aggressive forces from your fingertips.
