This might be kind of a dumb question but I have a feeling I'm missing something ...

Ok so I blew my left rear tire the other day, typical staggered-setup 245. What would be the downsides in terms of safety/handling to running the one 225 spare on the back and daily-driving it that way for a while, like a couple weeks? The other 3 are pilot sports, and the spare is the original Michelin MXX-whatever tire.

I don't know if I would want to drive too far with an 8 year old tire that probably hasn't been used before.

One of my rear tires tore when I took a turn too hard and I ran my spare on it for a while. Car did want to go towards one side though like I had a bad alignment, but I had it like that for a week or two before I put new wheels on my car. Didn't drive anywhere super far with it though, within like atleats 10 miles.

I think the risk is in running tires of different OD on the rear with a limited slip differential. I have no experience with an E36, but if it has a lsd, you risk burning it up if the diameters are different. If it's like the staggered E46 setup, although the widths differ, the OD is the same, so you should be okay.

The OD's are not significantly different. They are about 24.7" and 24.8" F/R. That's not a cause for concern.

The only downside is the handling, but if you don't drive like a nut, :D you'll be fine.
