I don't if anyone here knows the offsets of Mille Miglia wheels in 17" but I just put some 245/45/r17 tires on the back and I now have some rubbing when hitting some bumps and turning right. I didn't think these would be a problem at all, but I guess maybe the offset is all wrong for this car with these wheels. They were on the car when I bought the car so not me putting them on. My car to my knowledge is not lowered at all. There is plenty of wheel well gap so I don't really see where it is rubbing from. seems to have not been doing it the last two days but the second day I had the tires on I noticed it a bit and a day or two after as well. Any ideas or suggestions? I seem to have better grip now but the back of the car also feels a bit softer now taking turns is this normal? I had 225/45/r17's in the back before. I have 205/50/17 in the front I believe.
The tires I used to have were Cooper Zeon's

 

You need a 245/40R17 tire for the rear. The tires you have are 1" taller than stock. That is why they are rubbing. If I can help with the tires let me know.
