This may be a dumb question..

But what does the actual size of the wheel matter(I know it matters I'm just not sure why) besides the fact of wheelbite on certain boards. When I say size I mean like...69mm or 75mm. Thanks!

Not sure what you are asking but the height of the wheel can effect whether the board gets wheel bite...Imagine the bigger wheel hitting the board...

Wheels:
Often longboard wheels are much larger than regular skateboard wheels. The wheels have increased size because a smaller wheel has to spin faster to maintain the same speed. Also many smaller wheels have problems with rocks, sticks, and even cracks in the street or sidewalk. The larger the size the less likely the wheel is to stop rolling, and more likely to simply roll over the obstruction. Another factor is many wheels are specifically designed to grip the road, being made of different materials, while some are made to slide across the pavement without excess wear and tear on the wheel. Typically, longboard wheels are much softer than those on a regular skateboard. the benefits of this include a smoother, quieter ride as less of the vibration is transferred into the rest of the board. Wheel sizes will vary from around 65 mm to 90 mm (larger size wheels are available, but many boards cannot accommodate large wheels due to "wheel bite"). The hardness of longboard wheels is most often measured in durometer, softer wheels starting at 70a and tougher ones at 85a and above. The softness of a wheel helps determine the point at which it will skid when carving. Softer wheels equate to a more "grippy" feel. This can be useful when trying to slide, though it can also have very negative consequences at higher speeds.

EDIT: There are no dumb questions: only dumb people. J/k. Hope that pwnt your question.

Thanks. I get it now. More spins to get to the same.speed if the wheel is smaller.

Yes, and also the small rocks and sticks factor. Boards with big wheels usually ride "smoother" than boards with small wheels (same durometer). Wheelbite is more about the deck and trucks. Some people have 97mm flywheels with no wheelbite
