polyurathayne,
Wheels dont make a skateboard easier to turn on the skateboard trucks do that.
Cause they are made of urethane
no
Plastic deck, in the shape of a pointed "rounded" square with 2 corners; wheels made of metal (tons of vibration).
yes the sizes of skateboard wheels range from 40-70 mm
Bones wheels
it had really wide wheels
Wheels on skateboard can be as little as 50mm and go as big as 70mm (longboard wheels) and the softness rating verys. Smaller wheels are better for flip tricks, while bigger wheels are better for ramps and cursing . Harder wheels are better for tricks, while softer wheels are better for multi terrain cursing. What you want to do is figure out what you want to do on your skateboard (your skate style), from there you can choose the wheels that works best for you. Note for bigger wheels you are going to put risers on your board to prevent wheel bite.
Well it really depends on what kind your talking about. Sometimes they are made of plastic but if you're buying pro wheels like spitfire then they are hardend rubber
yes
