I was eyeing some Rotiform wheels and was wondering if any of these http://www.nokiantires.com/tyre?id=1...me=Nokian+WRG2 in run flat would work with them on a Cooper S.

 

The only one I see is the 215/45R17 91 V XL But you dont mention what width on the 17 inch rims. Just call TireRack.

 

Please give us more details about your MINI. R53? R56? Is it at stock height? lowered? Are you trying to achieve a flush stance?

 

Stock, R56. Uhh I don't know if I care about flush stance.

 

On a stock R56, the 205/50/17 RFTs should be fine on the Rotiforms. Keep in mind, the tire will be a bit taller than stock. Meaning your speedo will read slower than your actual speed.

Also, the wheels will stick out quite a bit. 17x8 ET30 on stock height will make it look like a 4x4.
But if you dont care about that, then by all means, go for it.

 

If I wanted them to match my speedo and not stick out what tires would I need or is that not possible?

 

Just find a tire with the OEM size 205/45/17.

As for not sticking out, you will need to find another wheel.
You probably want something along the lines of OEM fitment. 17x7 or 17x7.5 is what most people have.
Go on tirerack to see which wheels you like. Tirerack will pretty much guarantee a good fitment on your car.

 

Rotiforms are a somewhat aggressively sized for Minis just so you know. You will also want to make sure to get et30 rather then et20 to keep them sticking out of the fenders as much as possible. A 205/45/17 would be most ideal for matching speedo and stick out minimally.
