Does anyone know if there would be an issue with running a 16" spare on a rear axle that had 17" wheels / tires?
Why I ask...
I scored a nice set of 17" wheels the other day. But only the 4 were offered (and I forgot to ask about a 17" spare, anyway).
Was looking tonight for an 8-lug spare in 17"; found some, but not a lot out there, and $$$ for what would be just a spare.
Went to car-part, and found a pic of a door label from a 2500 - it showed the OEM wheels as 17", but the spare as 16". (I'll post a pic at the end of this post, for reference)
I know I could get away with running a mismatch on the front axle (even at highway speed) until I could get the flat fixed / replaced. My main concern is with the locking diff (Eaton G80 on most; mine is a Dana 60, but also has a locker)
Yes, I know I could swap a front to a bad rear, and then put the 16" on the front, if I had to.
