Hi guys. I have a 2002 IS300 Sportcross. I have Toyo's in the back and General exclaim's in the front. Both sets are summer tires and were both installed by the previous owner. I already know since they are summer tires they won't do anything in the winter. I picked up 4 rim's, the exact replacement. The 5 spoke design. So i have two 17x7's and two 17x 7.5's. My question is I'm buying winter tires from TireRack. The Winter force M+S. Does anyone know if i bought the 215/65SR17 tires will i have any fitment issues. The reason i ask is because I'm obviously raising the sidewall height but I'm also reducing the width since the height is going up. Am i right or do i have this all bass ackwards?? Any and all help is appreciated, please let me know what would be a good size to put on, since i live in Chicago and the weather here is pretty unpredictable. Here is the link for the tires and the sizes they are available in:
