70x68mm (Biggies) or 72x62mm (PK) are better for rougher roads… 63x53mm (Fatties) fits better visually for the blunt deck size… because of this I believe Doozies (63x64mm) are a great option, the best of both worlds, they are small and wide, and your cruiser will be not too heavy. PS: the spot in this video has a very nice and smooth asphalt, so Fatties go perfectly there
I love landyachtz too they have the best mini cruisers. If you get slightly wider king pins you can also get the 74mm PK GT(center set wheels need the 130 trucks probably) and that along with one or two of their soft risers make the best mini cruiser set ups ever if you ok with not being able to slide.
