Bald tire got a flat, unused spare going on: is my diff or center diff at risk? (1 Viewer)

[Polo]

I have four very bald tires and just got a flat. Now I have to put on my never-used spare (same make and model of tire, but never used).

The tires clearly are not the same diameter by something like a half inch, maybe more. Should I worry about running tires with different diameters?

Thanks for any insight you can provide.

(*yes, I'm ordering new tires all around, shipping might be about two weeks.)

Much less worse than driving around in a circle the same direction

You'll be fine and so will your 80.

cheers,

It will be fine. The only real risk would be the VC, but that would only come from extended highway speed travel.

Thanks for the prompt responses! Time to get out the jack and the lug wrench.
