probably. they are two different rubber compounds so they will have different levels of grip. I wouldn't use it.

yah, i think so too.

i would return it if you can, or get another one. which ever would work.
i personally dont like runflat tires as they run stiff and not much give.

the diameter difference is probably not enough to cause problem, but the grip could be different enough for spirited driving.

I agree with this part, but I also bet the corner that has the run flat will take more of a suspension beating because the tire doesn't give.

IMO, and I am in no way a tire expert (ChrisChhorn IS,) but if you're JUST streeting it, no problem, some spirited driving, be a bit more careful, unless your spirited driving is a mountain run... Then I wouldn't experiment...

it seems to be strongly advised to not mix rft with nrft, almost to the point where it seems even a worse idea than mixing completely different brand tires? is that true?

performance wise possibly. safety wise no. its safer to have the matching pattern on the same axle so the difference in the tread pattern in nasty weather conditions dont fight each other. each tread is made to push water out in a certain way. 2 different tires can counteract each other making your rear end squirrely.
