Prodrive P1 wheels (which size tires)
 

I was wondering which size tires to put on. I was thinking a 225/45/17. Let me get this straight 225 is the width of the tire, 45 is how high the sidewall is and 17 is the saize of the wheel???? Am I right?

Yes. You're correct. Actually that wheel is better w/ 215 since I believe the dimensions are 17x7, but 225's should work fine.

Get 225/45/17, If it is 17x7.5 you could even get 235's. The middle number is actually the percent of the width, is the height. So with 225/45, 45% of the width is the sidewall height.

An alternative, if you dont mind slight error on your speedo, would be 215/40-17 as this makes your overall diameter smaller, effectively changing your gearing for better acceleration
