Skating on a street with pebbles and cracks?Not cruiser wheels!
70mm or above is best. The larger the wheel the longer you will roll without pushing but the longer it will take to get up to speed. 70mm is what I use on my longboard for downhill riding. But if by cruiser you mean longboard then I don't know what size your skateboard can hold. Becuase you gotta remember if you are riding with your trucks real loose try leaning to either side and look for the amount of clearance between your wheels and deck. If it is a very small amount you don't want to get bigger wheels because then you run the risk of getting wheelbite while turning and then getting thrown of your board onto all those rocks. And no one likes road rash. Especially with little rocks inside the wound.
Usually a growling or humming noise that sometimes goes away when turning one direction.Could be cupped tires too.
If I member correct you have a air cooled v.w. if so it could be the steering damper. super beetles are bad for shakeing. hard to keep wheels balanced.
I have no problem with filmer wheels like bones atf 52mm. Hard wheels in the 96a are plain out too loud. The hardest I ever go is 90a with autobahn all road wheels.
Honestly, size is irrelevant. I#x27;ve litteraly rode on wheels that were almost worn to the bearing down brick roads and got crazy speed. Large soft wheels will be most comfortable, but slow. As far as not getting stopped by rocks and cracks, you may just need more practice. I can ride with a rock under my wheel, wheel completely stopped, and skid along just fine. Hell, one time I thought I was surely ****** when a stick stopped both my wheels. Buuutt, I just rode it out and turned that stick in to saw dust.
