"lifted" campers...
I know a few guys with small tag-a long Scottie type trailers they lifted to match the tow vehicles hitch height,and for better looks..one guy has a '63 Ford F-250 4x4 with 36's on it,and his trailer has matching tires and rims..he found by swapping in different bearings,a 2wd 8 lug front brake rotor was adaptable to his original trailer axle..it looks neat with big tires ,and that high off the ground!..he used custom leaf springs with 2" blocks,and had to trim the fenderwells a bit to clear the big tires..regular 235/16's would have fit with no cutting..he says its a bit squirrely at 70 mph,but he rarely goes that fast anyway,his truck is geared pretty low..
Others I've seen used bigger tires by making longer spring mounts and shackles,to lower them from the frame more..or they use custom springs and blocks..
Many camping trailers and utility trailers use 4 bolt hubs with a 4" bolt pattern..13" Chevy Vega rims and many imports used the same pattern,so its a simple way to upgrade to bigger tires..also some heavier duty axles used 5 lugs with a 4-1/2" bolt pattern,many older Dodge and Ford cars used that pattern,and their rims bolt right on..
I have a trailer with 5 on 5-1/2" pattern hubs,that Ford 1/2 ton pickup rims fit perfect on--it has spoked rims with 235/15 tires on it now!.

..
...car haulers and other larger trailers have 6 lug 6-1/2" bolt pattern that is the same pattern as stock 1/2 ton GM trucks like K5's and K10's..its nice to have the same rims on the trailer as the tow vehicle,then you'll always have the "right" spare with you!..
