The outside diameter of your vehicle wheel doesn't have to match your trailer, but the closer it is the better if you think you might have to use the spare for a long distance. And of course, if the outside diameter is too big you loose fender clearance. Trailer wheels have a zero offset ( the mounting flange face is in the center of the rim width). Vehicle wheels usually have the mounting face offset to the outside of the wheel. This problem is taken care of if the wheel adapter is the appropriate thickness.
In looking over the tire specifications of my tow vehicle and camper I am seeing that the bolt circle is identical (5 x4.5").
I am entertaining the thought of using my vehicle's spare tire as the temporary spare for the camper should I get a flat.
The vehicle spare I measure as 27 inches in diameter. The camper tire is specified at 26.3 inches. This is not perfect but it appears there would be enough clearance to the fender wall.
If the bolt pattern is the same between TV and TT would I still need a wheel adapter of a specific thickness or would I be looking for a wheel spacer?
Since a lot rides on getting the correct fit I am thinking that in the interim it might be a good idea to try out the vehicle spare to see if the fit is adequate.
Going this route I could just tighten the wheel adapter to my tire mount and have a lot of extra space.
I know I typically wouldn't camp far from home so I would just need to limp home and replace it once there with the real spare.
