The tires will fit on the rim, the sidewall will stick out a bit, your biggest issue is rubbing and making contact w/ the strut.

They gonna RUB on the strut. Prolly wont be able to even mount them. Why would you want to put MINIVAN tire size in a car???

You can mount them no problem, as the rim size is 15, it doesn't change.
As for installation on the car it might be a problem. That size comes on Silhoutte if I remember correctly.

Thats what I meant.... His question should be would it work on the car...Im sure its gonna rub, I work at a Tire Place.

The size is not just cut and clear with tires. The sidewall size is a proportion to the section width.

For example, you with your stock tire you have a 205 section width with a 65% aspect ratio. which means you have a 133.25mm sidewall (205 x 0.65)

On the other hand, with the 215 you will have a 139.75mm sidewall.

How this works overall is more significant.

for your stock size (FYI, 381mm=15")...

2(205x0.65)+381=647.5mm overall height (25.49")

now for the larger size

2(215x0.65)+381=660.5mm overall height (26.00")

So the 215s will be about 1/2" taller.
