I just got a new skateboard that came complete with everything (trucks, bearings, wheels, etc.). Everything is of pretty good quality with the exception of the wheels. So my question is: do the wheels make much of a difference when riding or doing a trick?
MM stands for millimeters - so if you paid any attention in math class you would know that 55 is bigger than 50. Go to a shop that sells sk8bds, this is a cycling forum.
honestly. its your wheels and bearing that are the most important(aside from trucks,). mainly affecting speed. and i guess landing the tricks when moving would be affected to. tho acually doing the tricks wouldnt change much that'd be your deck and kind of griptape
It matters because when you try to go faster or do a trick, there are different types of wheels. If you want a smooth ride or a controlled one you need a special type of wheel.
