The average skateboard wheel is made of Urethane. This is a plastic like material that is both resilient and very durable. Most wheels come in a variety of sizes, shapes, colors, and hardness. The average size wheel is 55mm. (diameter or height of the wheel). The bigger the wheel is, the faster it will roll.
The durometer is the hardness of the wheel. Australias Favorite Skateboard Shop carries medium to hard wheels -approximately 99a. Most skaters prefer a harder wheel for durability, speed, and controlled sliding ability. A slightly softer wheel (anywhere from 78 to 95a) may be preferred if the skater is riding on rougher ground. SIZE does matter. It is up to the skater on how they want to use it. Here are a couple questions to get you going in the right direction. First, what kind of Skateboarding are you planning to do?
Most skaters that do a lot of street skating involving ollies, flip tricks, and bench tricks choose to ride a 50mm to 55mm wheel. The smaller wheel is a little lighter and lower to the ground . This enables a quicker response when manipulating the deck during a trick. On the other hand a smaller wheel won't last quite as long or ride as smoothly.
Vertical skaters need a lot of speed for their style of riding. A larger wheel maintains its speed longer and actually will roll faster when it gets going. (Especially when dropping into a 12 or 15 ft ramp.) Most vert riders choose wheels larger than 55mm up to 65mm. If the skater is going to be riding a lot of ramps or backyard pools a 60mm wheel would be perfect.
All Terrain=52-60mm, 95-100a
Well rounded skaters are beginning to pop up all over the place. Along with all of the NEW skateparks opening all over. More individuals will be riding wheels from about 54mm to 58mm . This gives the skater a wheel w/ speed and durability that is still light and responsive enough for street tech.
These are alternate wheels to conventional modern skateboarding . The BIG soft wheels available at Australias Favorite Skateboard Shop are between 64mm to 105mm in size and usually around 80a hardness (extra risers may be needed). These wheels are designed mainly for cruising, transportation, and or downhill riding (not recommended for regular trick skating). This would also go for the Dirt wheels (112mm), which as the name describes are to be used on the dirt or cross-terrain. It is recommended to use these types of wheels on a longboard or old school style deck.
