You can run any kind of tire that fits on the rim, run flat or non-run flat. Some guys are even running tires wider than stock, that decision is up to you. I know there are a few running 295s in the rear on stock rim.
Your car will feel better once you get those run-craps off.
If you choose to go with non-run flats, then you must remember that the V did not come with a spare. So you can either purchase a single stock rim from your dealer (EXPENSIVE!!) or try to pick one up on ebay or even better right here in our very own classified section. Or you can do what I do and live on the edge and not have a spare.
