  The wheels of your skateboard can help or hurt your trip, so selecting wheels with the appropriate firmness is crucial. Softer wheels provide much more hold, making them a good choice for road skating, however, they are slower than harder wheels, which are a far better choice for smooth surface areas, particularly skate parks. Companies use durometer scales to indicate the hardness of the skateboards they manufacture. The smaller the number, the softer the wheel. Most manufacturers use A durometer scale. For example, a 78A skateboard wheel would be considered very soft, while a 100A skateboard wheel would be very hard. The durometer B scale is 20 points lower than the A scale and tends to be more accurate, especially for harder measuring skateboards. In other words, a wheel labeled 80B has the same hardness as a wheel labeled 100A. 1.Guide to  skateboard wheel  hardness Most skateboards are between 78 and 100 on the Durometer A Scale. The 78A to 87A are soft wheels, suitable for pave

1.What are skateboards made of? In the old days of skateboarding, skateboards were made of metal. The wheels are actually used by the skates, but the skater still attaches them to the board. Fortunately, this practice came to an end in the 1970s when Frank Nasworthy invented the first carbamate wheel. Since then, skateboards have been made of plastic polyurethane. However, it is often called polyurethane. This versatile material, which can be made to varying degrees of hardness, dominates the skateboard market. However, not all polyurethanes are the same, and not all wheels are the same. Different skateboard wheel brands have been experimenting with new material mixes to make the wheels more durable, faster, smoother, and slide better, and to make them particularly resistant to flat points. 2.

Skateboards are usually mass-produced in an industrial environment. They are made from polyurethane, a versatile and durable synthetic material. Frank Nasworthy invented the polyurethane skateboard wheel in 1970. Polyurethane wheels have a rubber-like grip on the road surface, expanding the potential of skateboard usage. Different types of polyurethane skateboards differ mainly in hardness, diameter, color, and shape. A durometer is a measure of wheel hardness. And diameters are the height of the wheels. Special chemicals and machinery are used to make polyurethane skateboards. Polyurethane Skateboard wheels Mix a batch of polyurethane. The chemical composition of the polyurethane is mixed in an appropriate proportion in the measuring machine. Metering machines are machines that heat, mix, and distribute polyurethanes. Add color. Add dyes or other types of pigments to the batch when the polyurethane in the meter is liquid. You only need to do this if you want the skateboard wheel to ha

Different types of polyurethane skateboards differ mainly in hardness, diameter, color, and shape. A durometer is a measure of wheel hardness. Soft wheels best suited for cruising on hard surfaces have lower hardness, hard wheels that absorb little vibration have higher hardness, and diameters are the height of the wheels.
