Skateboard wheels are usually made of polyurethane. The proportion of polyurethane in the grinding wheel is different, and the hardness of the grinding wheel is also different. Small wheels start fast, but lack endurance and are suitable for skill; large wheels are easy to slip on uneven ground. Skateboard wheels are also very special.
Factors that affect the effect of skateboard wheels
The shape of the skateboard wheel has an influence on the sliding effect, mainly including wheel diameter, contact width and side shape. The wheel diameter is very important. Generally speaking, the big wheel slides faster, and the small wheel accelerates faster, because the small wheel starts with little resistance, and the big wheel slides faster at the same speed.
At a certain sliding speed, the bearing wear caused by the increase in speed is small, especially for long plates. The big wheels glide faster on rugged roads, with a difference of a few millimeters.
Skateboard wheel manufacturers suggest that you can choose the outer diameter of the wheel according to the road conditions. The larger the diameter of the wheel, the stronger the ability to pass obstacles. However, this is not the same as crossing obstacles (such as a skate park) on a smooth surface. The diameter of polyurethane wheels can be up to 99mm, but due to the low board surface, the use of movable head bridges may cause wheel bites.
The contact width refers to the contact width of the wheel with the ground when sliding. The wider the contact width, the better the grip performance, and it is not easy to slip or local abrasion. Narrow wheels are not strong and easy to slip. Excessive pressure is easy to wear or local wear. The shape of the side of the wheel affects the effect of sideslip and grip.
