For those of you who have done this.. Did it require a wider axle so the tire wouldn't rub on the inside?
Thanks!
I think you are confusing backspace with off set.
Yes trailer rims are a 0 offset off the center line. Offset is measured in negative mm's and positive mm"s, such as -12 which would move the hub 12 mm to the back of the rim which in turns moves the wheel out from the car/truck.
Backspace is measured in inch's from the back of the rim to where the hub out mounts. your 4.75" you list is backspace. Depending how wide your wheel is will tell if you have a + or - offset. On the inside of the rim it will say what the offset is.
You can measure from the side wall of the trailer to the hub face and get an idea if it will work. But the tire can be wider than the rim width so take that into account.
Like has been said the wheel bore and spindle diameter will be the biggest issue. If you have aftermarket wheels that may help because they may have bigger bores to fit more vehicles. Another issue being its a 3/4 ton is the bolt pattern most likely will be 8 lugs. Most trailers are 5 lugs. You would need to know your bolt pattern on your trailer and truck and see if you can get an adapter (NOT spacer) to fit.
I am going through this now on my build and the bottom line is it is spendy to put car/truck/jeep wheels and tires on a trailer.
