What sized skateboard wheels should i get?

Question

I have a skateboard deck that measures 7.5 and trucks that measure 7.5. Ive heard that a lot of professional skateboarders use 50s and i have a 51s. What should i get? (Counting both a and mm.) Thanks.

Answer 1

if you skate vert(skate parks) the get 54-58mm if you do mainly street get 48-54mm  i have 54mm cause I do both  and you dont want wheels too hard or soft so like 100-90 or something

Answer 2

Wow i would never go with anything above 50, and 55s are just huge...I ride 48's not sure about how hard they are tho since i bought them off a friend a while ago...but i guess there around 105A or harder...

Answer 3

55s are smoother
