looking for info on the different stubs.

I have a trailer with BA xr6 wheels & i'd like to not have to go buy another rim & tyre & have to tow the extra weight. Insted, i'd like to get an E series offset hub & replace the hub & spare in my car.

Any idea if the stub sizes are the same?

Cheers

The trailer stubs are Ford five stud the offset is governed buy the length of you trailer's axle. You may be able to fit EL wheels to your trailer as EL are wide side out & BA are wide side in. It depends on how much mud guard clearance you have. TRY IT. Regards TPVM.
